OERs - Moving On

Some commentary to the UNESCO OER discussion list (unesco-oer-access).


I won't linger too much on this, but just to comment on Tom's thoughts...

First, the basic premise appears to me to be correct. We need to think of the structure of open educational resources as evolving to something beyone the current 'virtual textbook' or even the 'virtual learning package' model now being employed. Yes, I understand, that learning materials are being produced in some sort of packagaed format in order to adapt to lower bandwidth environments, where they will have to be distributed, not by internet, but by CD or even paper. But at the same time, it would be wise to plan for a world in which better bandwidth is becoming more widely available. And this means planning for a time when learning materials are not merely content packages, but rather, points in learning enviromnents that can be manipulated and exchanged.

Second, and in particular, when planning for a broader bandwidth environment, we need I think to consider the desirability and effectiveness of community-based resources. I have addressed this in previous work. The current model, where academic content is produced and packaged (at great expense) by universities and publishers in developed countries, and then distributed (as a gift) to people in other nations, is a model that has several weaknesses. First, it directs funding for learning resources to the institutions that least need additional funding. Second, it does not support the development and sustainability of similar institutions in the other countries. Third, the materials produiced either reflect the culture and values of those that produced them, o4r must be (and additional time and expense) be 'localized' for wide use. And fourth, the production of large and static learning materials is at odds with an information environment favouring smaller and much more dynamic units of learning. Consequently, I have argued that we shoudl address ourt attendtion to the development of skills and capacities to enable locally-based learning communities to produce their own learning resources, contributing as equal partners in a worldwide knowledge exchange.

Third, while it is true that we need to be looking beyond current (computer) technologies, we should not be lulled into beliegving that mobile phones, no matter how widespread the devices, are a suitable alternative for the delivery of online learning. First of all, mobile phones have significant bandwidth limitations, and even phones with good 3G access will have difficulty playing videos or downloading larger content. Second, small mobile devices pose significant usability challenges, so much so that sites offering mobile content are encouraged to synch these accounts with web accounts in order to enable users to enter data and upload photos. Mobile devices are not suitable for the creation or consumption of large and complex information entities. And third, mobile devices, unlike computer systems, are controlled by the access providers, which increases costs and places barriers in the way of the use of open source applications and free content. This explains why they are being relentlessly promoted as an alternative to genuinely free and open access to information, but also why they should not be acceped as such.

The Point of Freire

Responding to Joanne Jacobs.

For information and links on Freire (none are provided in the article, naturally), see http://www.infed.org/thinkers/et-freir.htm
I think the fact that the people worried about (what they call) ‘core knowledge’ are attacking Friere in itself demonstrates the relevance of his work.

When they say “there’s no mention of “testing, standards, curriculum…” etc., then so much the worse for testing, standards and curriculum.

The point of Freire’s work is to encourage and empower people to find out what they actually need to learn (instead of what they are told to learn) and to learn it for themselves, working together.
The message remains relevant today. If you are a passive learner, and learn only what your educators teach you, then you will play a passive role in society, at the sway of those who would lead you, unable to make your own way when conditions change.

A people, if it wishes to be successful, will inculcate values of self-reliance and personal direction in its citizens. Rather than fostering an educational system based on the maxim “learn what you are told,” as the core knowledge people would have it, you foster a system where people build their own education.

It is no surprise that Freire was jailed by Brazil’s military dictatorship. Authoritarians tell you what you need to learn. Authoritarians prefer people who are quietly obedient. Authoritarians prefer people who do what they are told, and who do not rock the boat with unauthorized and unsanctioned learning.
The red-baiting tactics being used to discredit Freire are typical of those who wish to obscure the core of his message, that a people free themselves from oppression only when they take control of what they learn and who they are.

Advice for a Liberal Candidate

Responding to James C. Morton:

> As we come to the Convention later this week remember, there is a Liberal forest growing.

Well maybe, but if so, try to do some good, and don't just squander it. Simply putting into place a clone of the current government is insufficient.

Try to be a little bit visionary and maybe to recall some of those Liberal pronciples that have served the party well in the past.

- Canada used to have a rail system it could be proud of, until it was dismantled by Airbus Mulroney in the 1980s. It's time to convert part of the auto sector into the production of high-speed rail components, and to establish a nation-wide network. We only get one chance to do this, because ti will be prohibitively expensive after the recession and after the productive capacity has been dispersed.

- Canada used to be seen as a leader in environmental responsibility, even if our practices didn't always pass muster. But we can become leaders again by investing in energy-efficient technologies such as solar and wind power, hydrogen production, LED lighting, and electric vehicles.

- Canada used to be a model of social fairness and social justice, and these are essential ingredients in a multicultural society. Respond to the recession by ensuring that nobody loses their home (or rental), that nobody is put onto the street, that nobody goes hungry. This is not just aid to the indigent. Piut in place programs that will help such people retrain, retool, and reorient themselves - but make these voluntary, so that people have a sense of investing in themselves.

- Canada was once a leader in online access and services, but investment in infrastructure has been stagnating since the privatization of the telecom industry (which piled up debt in takeovers and acquisition, not actual production). We need a national broadband initiative, much like was proposed before Martin took power. And Canadian culture, content and learning should be freely available online.

- Support for the arts and culture used to be a hallmark of Canadian government policy, but more recently governments have taken to pandering to U.S. copyright lobbyists. Resist these lobbies, preserve Canada's tradition of sharing (through, eg., the media levy) and promote Canadian talent directly through a revitalized arts and culture program (the one our government has been cutting back on recently).

- Canada's education system has been the envy of the world, with the Globe and Mail a few years back suggesting that our children may be the best educated in the history of the world. But investments need to be made in the regions, access to electives and specialized education (such as provided in Edmonton) made the standard nationally, and community-based and focused learning made the norm.

- Canada's international reputation as a peaceful and safe place was created by employing less police power, not more. The use of force by police should be limited, with tasers treated more like guns than like batons. Legislation restruicting guns should be entrenched and extended, and effort taken to improve the efficiency of the gun registry. Internationally, Canada should return to the role of peacekeep rather than active combatant.

These are just a few things, but you get what I'm after. It's not enough to simply take power. Try to do some good, to do something worthwhile.

New Technology Supporting Informal Learning

Abstract

We often talk about games, simulations and other events in learning, but these technologies support only episodic learning. Equally important are those technologies that provide a context for these learning episodes, an environment where students and interact and converse among themselves. This paper described experimentation in the development of distributed online courses and in software - particularly, the personal learning environment - that support the formation of connections between the far-flung pieces of such courses. This work, in turn, is suggesting and supporting the model of learning described in the first section, that of a course network supporting and informing an ever-shifting set of course episodes. This in turn suggests a pedagogy of participation rather than retention, and even suggests distributed and locally-based forms of evaluation and assessment. Future developments will focus on realizing these concepts as software or at least software prototypes. The intent of such systems is to to facilitate the conversation and interaction around episodic learning events in a distributed environment, transforming them from elements in a linear flow-based design to free-floating objects in an environment.

Context

Online learning today is beginning to be dominated by developments in games, simulations and related technologies. (Akili, 2007) And there is no doubt that this is a positive development for the field. Such applications are almost unambiguously beneficial for the student. In addition to providing an engaging and immersive environment for student learning, substantially improving motivation and interaction with the learning material, games and simulations are able to support learning in complex environments, offering a subtlety simple instruction-based or lecture-based learning cannot offer. (Squire, 2005)

What most characterizes games and simulations is that they are not merely forms of instruction, they are environments, into which students must immerse themselves in order to participate. (Foreman, 2004) As environments, they model complex relationships between variables, resulting in an experience that is unpredictable and unique each time played. (Aldrich, 2005) It is this feature, and not simply the action and the graphics, that motivates learners and draws them in. With the addition of interaction with other participants, as seen in massive online gaming environments, the experience can be almost addictive. (Ng & Wiemer-Hastings, 2005)

That said, these environments, by their very nature, require intense preparation on the part of the designer. In addition to graphics and game play, there is the content of 'storyline' to consider. (Rollings & Adams, 2003) In the case of learning environments, the planned learning objectives or outcomes need to be programmed into the game design, involving a further layer of preparation. Consequently, games and simulations fall into a category similar to lectures and presentations in that they involve statically designed learning objectives and strategies. (Amory & Seagram, 2003)

As a consequence, interaction with such environments, even the most immersive and addictive game or simulation, must have a start point and an end point. Such systems are by their very nature episodic. Because they must be designed in advance, they are inherently static, at least at the level of overall design and framework. Consequently, they represent a separation between the learner's in-environment experience and his or her wider life of leisure and work. Consequently, in order to place games, simulations and other episodic learning events such as classes and lectures, into the context of the student's wider life, a wider frame of reference is necessary. In this wider frame we would expect to find a wider environment of conversation and interaction with friends and associates. This wider frame situates, and plays a significant role in the selection, of episodic learning events.

Why is this necessary? In short, it is simply impossible for simulation, game and learning designers to design unerringly for the learning needs of the student. First, and significantly, we often do not know what it is we want to teach the student. (Caine & Caine, 1997) Today's environment is variable, which means situations - and hence, fact - change fluidly. One day Pluto is a planet, the next day it is not. One day Czechoslovakia is a country, the next day it is not. One day capitalism is the unassailable foundation for our economic system, the next day, following a market collapse, it is not. Moreover, today's environment is complex. The relations between variables cannot be described or even predicted. An understanding of such things as the financial system or global climate change requires a subtle and ever-changing perspective on the discipline.

Second, learners themselves are changing. There has been much discussion in recent years about the rise of the 'digital native' or of the 'net generation'. It has even been suggested that our interactions with modern communication technologies change the way we think. Even if we reject such descriptions as students as overly broad and inaccurate generalizations - and there is good reason for doing so - it is nonetheless the case that the needs, capabilities and interests of the target audience is rapidly shifting and changing. As much as it is tempting to say that human nature is unchanging, it appears nonetheless the same that human experience is endlessly varied, resulting in any number of approaches to media in general and learning in particular. A child raised on text alone will think and learn differently from a child raised on cartoons or a child raised on Facebook. (Peters, 2006)

In part, our best response to the variability and complexity of the subject matter along with the changing nature of the learner is to design systems that are decentralized, to push learning decisions down the hierarchy or out to the edges of the network. (Wiley & Edwards, 2002) This logic, which is characterizing not only new learning but also new approaches to business and management (Malone, 2004), is based on the idea that those who are closest to the situation are in the best position to make decisions about it. In the military, this means that company commanders, and not generals, must make tactical decisions. In business, this means that salespeople and customer service representatives must determine marketing policy. And in learning, this leans students must be empowered to make their own learning decisions. This is the basis for the models and strategies that characterize what has come to be called informal learning. (Cross, 2006)

But there is in addition a second and critical aspect to this wider environment of conversation and interaction. It is not merely to create a network into which to situate episodic learning, but rather, to create a network that learns and thus adapts and reshapes itself based on those conversations and interactions. (Downes, 2007) We need to consider learners not only as the subjects of learning, entities to whom we deliver learning content, but also the sources of learning, functioning as the perceptual input for the wider network. (Marotzki & Specht) The things we say, the things we choose to read or view, the things we link to, the people we send messages to - all of these constitute input to the learning network, causing it to reform, causing it to present, say, one learning episode rather than another, one game rather than another, one simulation rather than another. And, moreover, our reflections and commentary on various games, simulations and learning events constitute feedback for those systems, modifying them internally as well, either directly, or through a series of design iterations, just as we see in (for example) agile programming. (McCall, 2005)

Learning networks capture an essential element in learning today, the simple fact that we don't know what we want to teach. Indeed, it is often suggested that the best we can manage is to teach students how to learn, and to encourage them to manage their own learning thereafter. But even this principle is subject to changing affordances of technology and changing capabilities of students; how we learn itself is something that changes, and cannot be precisely taught. The way musicians learn, for example, changes as they grow from novice to expert. (Münte, Altenmüller, & Jäncke, 2002) For this reason, we need to see the educational system itself as adaptive rather than merely prescriptive.

We are seeing the development of specific instances of this approach to learning today. For example, a learning system called Company Command, designed by officers in the U.S. military starting in 2000, is essentially a learning network composed of company commanders. (Dixon, Allen, Burgess, Kilner, & Schweitzer, 2005) While most traditional military training is conducted from trainer to learner, Company Command starts with a significantly different proposition: that knowledge exists in the minds of the members or participants, and this knowledge is derived from their direct (and recent) experience in the field.

In addition, the need for content and support emerges from conversations among the participants. These interactions are able to reveal not only what company commanders know, but also what they don't know (and need to know). The interaction, in other words, meets and addresses an objection often put of self-directed learners, that they don't know what they need to know. (Clayson, 2005) While this may be true, through participation and interaction in this wider environment they are able to identify these needs (as expectations, for example), and hence to select and conduct appropriate learning episodes. (Chickering & Ehrmann, 1996)

The model of Company Command is one that has been repeated many times on the internet. Company Command itself began as one of thousands of Drupal applications. The core purpose of Drupal is to facilitate the creation and management of communities online (Drupal, 2009), including communities of practice of the sort that typify such cases as Company Command. Drupal, an open source content management system, enables the creation of individual accounts, the creation of discussion posts and pages and other content, and the sharing of this content online with other community members. Many other systems provide similar functionality (CMSWire, 2009), and in learning, the learning management system (LMS) provides the wider conversational context for in-person or online learning episodes. (Garrote, 2007)

More recently, social networking technologies have come to be applied to content and learning management systems. (Dignan, 2008) The core of a social networking technology is the capacity to create links between members in a community - to create, in other words, social networks. These links are usually created explicitly, through the declaration of each of the as 'Friends'. Often, the creation of links is associated with the creation of content, as in content management systems. The last few years have seen the development of social network services online such as Facebook, Friendster, LinkedIn, and MySpace to name a few) as well as a service for creating social networks, Ning. (boyd & Ellison, 2007)

Social networks represent a gradual decentralization of content and contact online. Content management systems (and before them, email lists and usenet groups) organized people and content by hierarchy, by topic and content thread. In social networks, such associations are created by the users themselves. Topics, for example, are not assigned centrally, but are instead created by individuals 'tagging' certain content with terms or categories they choose themselves. (Barsky & Purdon, 2006) Each person's social network on a social networking site, moreover, is unique; there is no definitive grouping of people, only a clustering of people with more or less similar interests.

Software to create social networks is the logical successor to content management systems such as Drupal, and in the field of learning, the most prominent such system is Elgg. In addition to supporting content creation and the creation of networks of friends among members, Elgg allowed people to import content from remote sites and to syndicate this content through the use of RSS feeds. (Elgg, 2009) Systems such as Elgg therefore combine the functions of content management and social networking.

In summary, then: we often talk about games, simulations and other events in learning, but these technologies support only episodic learning. Equally important are those technologies that provide a context for these learning episodes, an environment where students and interact and converse among themselves. Historically, this role has been played by the content management system, while more recently systems supporting social networks have also come into prominence. Such systems represent a partial decentralization of the management of learning, pushing some decisions (such as association with other learners or clustering of material into categories) from central decision-makers to the learners themselves.

Current

At the turn of the century, the dominant model of online community proposed by pundits was one that could be characterized as a 'destination resort'. It would be, suggested writers like Hegel and Armstrong, a complete interest-based community revolving around travel, homeowners or personal finance. (III & Armstrong, 1997)Members would be attracted through marketing and content, would be encouraged to contribute content, would become loyal to the community through friendships and interaction, and would be monetized through value-added services and sales. (p. 59) What developed instead resembles barrios more than resorts: a complex interweaving of online services, sites, interactions and applications developed ad hoc rather than at the behest of some community planner.

Also at the turn of the century, it was thought that online services would interact with each other in an organized and managed way - they would, in other words, be "choreographed". The classic example involved a travel service where one central provider - the agent - would send requests via web services to hotels, car rental agencies, airlines and even caterers in order to seamlessly manage the experience. (Yendluri, 2003) What developed instead were random, individualized and often ad hoc assemblages known as 'mash-ups', these based on lightweight communications technologies such as REST, AJAX and APIs. (Rushgrove, 2007)

Far from being neat and organized, the internet has become complex. Far from settling into one web community, users jump from service to service, creating (and discarding) new identities as needed. A typical web user may have multiple 'home pages' - their personal blog, their photo page on Flickr or Picassa, their Google Reader account, shared documents through Zoho, their video page on YouTube, their Twitter account, their profiles, on Facebook, MySpace and LinkedIn, their Wikipedia login, their email accounts, and (often least) their university LMS login. While real friendships and communities develop through this mélange, loyalty to online sites and services is limited and fleeting. (O'Brien, 2007)

It is in this environment that the University of Manitoba's Connectivism course was developed in the fall of 2008. (Siemens & Downes, 2008) Developed by George Siemens and myself, at least one intent of the Connectivism course was to facilitate the transition from a neat, constrained and centralized learning management system to a distributed environment in which students and instructors employ multiple online services and applications. (Downes, Tools, 2008) Consequently, the Connectivism course must be viewed as one of the first distributed courses to be created - not simply distributed in terms of time or place, but distributed in terms of website or application.

Much has been or will be written about the course elsewhere, but it is sufficient and relevant to say that roughly 2200 people signed up to participate in the course. While the course was offered as a tuition-based for-credit course, in order to foster the network dynamics we also chose to open the course to all participants. (Siemens, On Finding Inspiration, 2008) In this we were following not so much the model offered by OpenCourseWare and others, which made learning materials freely accessible online, but rather David Wiley and Alec Couros in offering actual course instruction available online. We wanted students not merely to consume learning materials, but rather, in the manner of the wider environment discussed above, to contribute to the learning through conversation and interaction. (Siemens, Narratives of Coherence, 2008)

To this the students contributed in droves. The central course aggregator listed 170 separate weblogs or similar RSS feeds contributed by students, each of whom used their own blog or website to participate in discussion. (Downes, Feeds, 2008) Additionally, thousands of comments were contributed to the central Moodle forum, three separate areas in Second Life were contributed, Google Groups were created, a Ning was created, and more. In fact, student contributions to the course continue to this day even though the course was completed in December, 2008.

As no viable mechanism for connecting the disparate and distributed course contributions exists, we adapted my newsletter software, gRSShopper, for the course. (Downes, gRSShopper, 2008) This software was developed out of a need for a personal online web space to do more than was possible in Drupal (in fact, I document my trial with Drupal in a series of posts). gRSShopper is available as free and open source software for public download.

gRSShopper is a prototype personal learning Environment (PLE). The PLE is a concept developed in 2005 in conversations with and among members of JISC CETIS and their friends and associates. (Wikipedia, 2009) The idea of the personal learning environment is that it performs many of the functions of a content management system and of a social network system but from the perspective of the individual rather than the community or the institution. (Attwell, 2006) Hence, the PLE may be understood as the intersection of the multiple home pages employed by any given individual. In the first instance, the PLE is a concept, rather than an application - it is the idea that a person's web presence can be distributed. (Attwell, Graham Attwell: "Knowledge is best shared and developed through communities of practice", 2007) And in applications such as gRSShopper it is the instantiation of that idea in a personal application.

In the context of the Connectivism course, the prototype PLE proved to be an admirable teaching application as well. While online course content was provided to students using the more traditional mechanisms of a Moodle learning management system (to host discussions and conversations) and a course Wiki (to host the course outline and links to learning resources) the use of gRSShopper allowed us to send, by email and RSS, a daily newsletter to students' own email or RSS readers. (Downes, The Daily, 2008) In this way, we were linking course material out, to students. Student registrations to the email newsletter remained at a constant level of 1870 subscriptions through the full duration of the course.

Additionally, however, gRSShopper has a built-in RSS aggregator. Hence, we collected the feeds from the 170 separate blogs and websites created by participants and stored the student contributions in the gRSShopper database. This allowed us to filter content by tags and to include this content into the daily course newsletter mailouts. We selected and distributed material containing the 'CCK08' tag (thus not diluting the newsletter with unrelated material) . We also created (manually) links to online events such as Elluminate and Skype discussions, sessions in Second Life, occasional videos, diagrams and other resources. (Siemens & Downes, Wiki, 2008)

Because there were so many people contributing to the course, and because the content of the course actually shifted and varied according to participation and input into the course, it was necessary to emphasize to students that their role in the course was not to attempt to assimilate all course content. This was neither possible nor desirable. Rather, students were told that their role was to select and sample course content, pursuing areas of interest, reading related material from both within and outside the course, and then to contribute their unique perspective based on this reading. (Siemens, Where does the learning occur??, 2008) Students would be evaluated, we said, not based on their retention of course material, but rather, on the basis of their contribution to the discussion, their interaction and sometimes collaboration with other participants, and their evolving capacity to work within a network to produce new knowledge in the field.

Indeed, the world-wide and distributed nature of the course suggested an alternative method of evaluation entirely, one that separated course content from evaluation. Students from other countries and other institutions could register into the course as students and participate in the course, and use their work in the course as material submitted for evaluation in their own home institution. To that end, we made all assignments and evaluation metrics available to all participants, to share with their home institutions. At least one person requested, and was evaluated, in this fashion.

To summarize: we are currently seeing experimentation in the development of distributed online courses and in software - particularly, the personal learning environment - that support the formation of connections between the far-flung pieces of such courses. This work, in turn, is suggesting and supporting the model of learning described in the first section, that of a course network supporting and informing an ever-shifting set of course episodes. This in turn suggests a pedagogy of participation rather than retention, and even suggests distributed and locally-based forms of evaluation and assessment.

Future

Future developments around the concept of the conversational and interactive environment begin with preparations for a second offering of the Connectivism course in 2009. In particular, work to date has revolved around the idea of simplifying the production of course newsletters. Even with content aggregation, these were taking the author (me) about an hour every day, as course content (such as planned online events, readings, etc.) needed to be input into the newsletter body. To this end, a system to develop serialized feeds (Hirst, 2009) was created, in order to automate the distribution of scheduled course content. (Downes, Serialized Feeds, 2009)

The idea of a serialized feed is to create elements and to store them into a data base. Each element of course content corresponds roughly to a blog post - that is, it is dated, has its own page, and may link to external resources or services. Each post is then given an offset value which stipulates, in number of of days, how long after the onset of the course a material should be delivered. When a course is initiated (by the registration of students into the course) the timer is started. The system automatically delivers a newsletter each day. Student contributions, filtered for the CCK08 tag as before, are harvested and inserted into the newsletter. Then any content from the database with an offset matching the current course day is also added. The completed newsletters are distributed by email or RSS.

Serialized feeds are one aspect of a more general development program being undertaken around the idea of the personal learning environment. As noted above, the PLE merges the function of the content management system with the social network service, and does so from the perspective of individual students. Hence the PLE could be depicted as being a node at the centre of a network, connected (using standards such as RSS) to content and other services across the web. Examples of such services in Scott Wilson's paradigm document include Flickr, 43things, LiveJournal (a blogging service), an academic publisher, and more. (Wilson, 2005)

In the PLE project being undertaken by the National Research Council, the functionality of the PLE is depicted in four major stages: to aggregate, that is, to collect content from the individual's and other online content service providers, where aggregation includes elements of recommendation, data mining and automated metadata extraction ; to remix, or to organize content from several different sources in different ways, including through automated clustering; to repurpose, or edit, localize, or otherwise modify or create new content; and to feed forward, or send the content to subscribers and other web services, either via RSS syndication, email, Twitter, or other relevant services. (Downes, Theory of Learning Networks, 2004)

When viewed from the perspective of a collection of students taking a class (such as, for example, the Connectivism class), what is created using the PLE is not a recreation of the capabilities of the learning management system, but rather, a learning network. Though through the use of serialized feeds and similar mechanisms educational institutions and instructors can feed content, services and resources into the network, actual structures of the network, along with many of the resources exchanged in the network, are created by the students themselves. These structures are reflective of the students' interactions with each other and with the wider community (surrounding a particular content domain) and hence the structure of the network varies as student experience varies. (Levin, 1995) A network of PLEs is a learning network.

As suggested above, the pedagogy of such a network is strikingly different from what we might find in a content-based (content-management based) course. The order and structure of the content is dissolved; while episodic content (such as books, simulations or lectures) maintain an internal logic and structure, the linear or hierarchal structure that previously defined courses is entirely absent. This does not mean that the relation between course, participants and content is completely unstructured, only that the nature of the structure has changed. It makes more sense to think of learning episodes as objects that inhabit the wider environment, the conversational and interactive environment that constitutes the course. (Downes, Learning Objects: Resources for distance education worldwide, 2001) The entities in such an environment - individual students, as instantiated as PLEs, along with course episodes, as instantiated as readings or services or games - interact with each other much in the way physical objects interact in an environment: not according to any central plan, but via the internal motives and affordances of each object.

The computational structure for such a model exists in the field of object-oriented programming, where computer programs consist not (simply) as lists of instructions to be followed, one after another, in a linear or branching manner, but rather in an open-ended consideration of the properties and states of each object. (Meyer, 1997) On the internet, the best example of such systems are the Multi-User Dungeons (MUDs) that were developed in the late 80s and early 90s, where objects could have properties and methods (functions) that influence those properties, and could send messages to other objects invoking methods in those objects as well. (Cuciz, 2004)

This model informs the design of learning experiences as well. In traditional learning design, as instantiated by (say) EML or IMS-LD, learning design consists (essentially) of a flow of learning experiences, choreographed (or directed) just as web services manage access to different travel resources, where there is a script, planned learning outcomes, and localized, content-based evaluation or assessment. (IMS Global Learning Consortium, Inc., 2003) The traditional model suits a world of content management systems where the delivery of learning episodes as well as the content of those episodes can be anticipated and planned in advance. (Vries, Tattersall, & Koper, 2005)
An alternative to traditional learning design, state-based learning design, will be proposed, such that the presentation (and even the content) of a learning episode will vary depending on the relative states of the objects in a given environment - that is to say, the set of values and methods present in the set of objects in a given interactive space (defined by linkages between individuals and content). In state-based learning design, learning resources are not arranged as sentences in a paragraph or chapters in a book, but rather, are used as a form and means of communication, more in the manner of words in a vocabulary. Their use is suggested by content rather than mandated by learning imperatives.

Such a change is essentially a migration of IMS Learning Design into a Rule-Based design more characteristic of object oriented systems. (Martínez-Ortiz, Sierra, & Fernández-Manjón, 2009) Rules may resemble simple functions, such as "show an activity" or "hide an activity" or may represent more complex interactions. While traditional IMS learning designs could be mapped into such a system, the reverse would not always be true, as such a system would be capable of more open-ended interactions not describable in a flow-based format. The interaction between user and content would resemble the dynamics and interplay of a simulation or a game. Indeed, these latter learning episodes would take their place as objects within this larger learning environment.

To summarize: future developments have focused on realizing the concepts displayed in the Connectivism course as software or at least software prototypes. The intent of such systems is to realize the objective of the design of the Connectivism course, to facilitate the conversation and interaction around episodic learning events in a distributed environment. This realization is essentially that or re-orienting learning objects, transforming them from elements in a linear flow-based design, such as described in IMS-LD, to free-floating objects in an environment, activated by the triggering of rules in an object oriented environment.

Blogs in Education

Submission for a forthcoming STRIDE handbook for The Indira Gandhi National Open University (IGNOU). See related handbooks here.


What is a Blog?

A blog is a personal website that contains content organized like a journal or a diary. Each entry is dated, and the entries are displayed on the web page in reverse chronological order, so that the most recent entry is posted at the top. Readers catch up with blogs by starting at the top and reading down until they encounter material they’re already read.

Though blogs are typically thought of as personal journals, there is no limit to what may be covered in a blog. It is common for people to write blogs to describe their work, their hobbies, their pets, social and political issues, or news and current events. And while blogs are typically the work of one individual, blogs combining contributions of several people, ‘group blogs’, are also popular.

While the earliest blogs were created by hand, blogging becam widely popular with the advent of blog authoring tools. Among the earliest of these were Userland and LiveJournal. Today, most bloggers use either Google’s popular Blogger service or WordPress. These services allow users to create new blogs and blog posts by means of simple online forms; the writer does not need to know any programming or formatting. As a result, blog aggregation services such as Technorati have reported that tens of millions of blogs have been created.

Blogs are connected to each other to form what is commonly known as the ‘blogosphere’. The most common form of connection is form blogs to link to each to each other. Blog authors may also post a list of blogs they frequently read; this list is known as a ‘blogroll’. Blogs may also be read through special readers, known as ‘RSS readers’, which aggregate blog summaries produced by blog software. Readers use RSS readers to ‘subscribe’ to a blog. Popular web-based RSS readers include Google Reader and Bloglines.

While blogs once dominated the personal publishing landscape, they now form one part in a much more diverse landscape. Many people who formerly write blogs are using social networking sites such as MySpace or Facebook. Others use ‘microblogging’ services such as Twitter. And blogs, which began as text-based services, have branched into audio blogs (also known as ‘podcasts’) and video blogs (‘vlogs’). Authors typically upload a wide range of multimedia content such as art to sites like Deviantart, videos to hosting services such as YouTube, slide shows and PDFs to SlideShare and photos to sites like Flickr.

Why Use Blogs In Education

Blogs are widely popular in education, as evidenced by the 400 thousand educational blogs hosted by edublogs. Teachers have been using them to support teaching and learning since 2005. Through years of practice, a common understanding has formed around the benefits of the use of blogs in education.

Because blogs are connected, they can foster the development of a learning community. Authors can share opinions with each other and support each other with commentary and answers to questions. For example, the University of Calgary uses blogs to create learning communities.

Additionally, blogs give students ownership over their own learning and an authentic voice, allowing them to articulate their needs and inform their own learning. Blogs have been shown to contribute to identity-formation in students. (Bortree, D.S., 2005).

Further, blogging gives students a genuine and potentially worldwide audience for their work. Having such an audience can result in feedback and and greatly increase student motivation to do their best work. Students also have each other as their potential audience, enabling each of them to take on a leadership role at different times through the course of their learning.

Moreover, blogging helps students see their work in different subjects as interconnected and helps them organize their own learning. Working with the teacher and informed by blogs authored by experts in the field, students can conduct a collective enquiry into a particular topic or subject matter creating their own interpretation of the material.

Blogs teach a variety of skills in addition to the particular subject under discussion. Regular blogging fosters the development of writing and research skills. Blogging also supports digital literacy as the student learns to critically assess and evaluate various online resources.

How To Use Blogging In Learning

Begin simply. Most uses of blogs in the classroom began with the instructor using blogs to post class information such as lists of readings and assignment deadlines. This fosters in the teacher a familiarity with the technology and with students a habit of regularly checking the online resource.

Lead by example. Before requiring students to blog, instructors should lead by example, creating their own blogs and adding links to interesting resources and commentary on class topics. This not only produces a useful source of supplemental information for students, it creates a pattern and sets expectations for when students begin their own blogging.

Read. Students should begin their entry into blogging by reading other blogs. Teachers should use this practice not only to demonstrate how other people use blogs to support learning but also to foster critical thinking and reading skills. Teaching how to respond to blog posts is as important as creating blog posts.

Create a context. Like the author facing a blank sheet of paper, a blogger will be perplexed unless given something specific to write about. Have students blog about a current issue, about a specific peice of writing, or some question that comes up in the course.

Encourage interaction. Blogging should not be a solo activity. Encourage bloggers to read each other’s works and to comment on them. Encouraging students to set up an RSS reader with each other’s blogs will make reading and commenting a lot easier. Teachers, also, should subscribe to student blogs and offer comments, again setting an example of the expected practice.

Respect ownership. A student blog becomes important because it is a manifestation of his or her own work. However, to have this value, a student’s ownership of a blog must be genuine. While reasonable limits or codes of practice need to be respected, student bloggers should have the widest latitude possible for personal expression and opinion.

Address issues immediately. The most significant danger to students online is posed by other students. In particular, bullying (or ragging) is a significant problem. It is important to spot instances of bullying as soon as they occur and to take steps to prevent further incidents. Teachers should educate themselves as online bullying can be invisible and hard to address.

Relativism and Science

I don't want this to be a long post, but Rose sent me this, which people should watch. Then I'll add some comments.



OK, I hope you enjoyed that.

So the question I want to address is, "How can you be a relativist?" Because, as the video says, there is knowledge. You don't walk out the second floor window, and we can extend our lifespans with medicine, and all that. It's not all a big mystery, and it's not all "anything goes."

Quite right. There is knowledge, and it's not all "anything goes." But it does not follow that relativism is false.

Listen to the video carefully. As it says, science is the willingness to change our views based on the evidence. If you can show us how homeopathy works, and how it works, says the author, I'll go running down the street shouting "It's a miracle."

To the scientists, to the empiricist, to the reasonable person, beliefs are based, through reason, on the evidence. It is precisely the mark of the unreasonable, of the unscientific, that they will not change their beliefs even in the face of evidence, that their 'knowledge' is constant, unchanging.

One should ask, rather, how can someone be an empiricist, how can someone base their beliefs and knowledge on the evidence, and not be a relativist? If one's own belefs and knowledge might change from time to time, why is it not reasonable to suppose that others' might as well?

Indeed, it is pretty evident that each of us has his or her own distinct set of experiences. A very different body of evidence on which to base their knowledge and beliefs. It would be a miracle were it to turn out that everyone's knowledge and beliefs were the same!

Yes, it may be argued that there is an element of commonality to people's knowledge, that the world is the same world for everyone, and that we go to great effort, through scientific method and repeatable, testable, experimentation, to ensure that people have the same experiences, and thus, the same knowledge and beliefs.

That's quite so, and for some big gross things - like the influence of gravity - it appears that we may be able to achieve some constancy, by carefully regulating our experiences to achieve precisely this result. But as the world is constantly changing, and as each of us is limited to our own direct limited point of view, our capacity to achieve constancy is limited, and always subject to question from the periphery, from personal experience.

Because people have different points of view, because people have different experiences, they come to mean slightly different things by their words, to develop slightly different principles of reason, to develop slightly different pictures of reality. Multiply this over a lifetime, and over seven billion people, and you have the recipe for relativism.

Our differences in knowledge and belief - our legitimate differences in knowledge and belief - lie precisely at those fault lines where our personal experiences differ. A person borne in injustice will come to have a different view of fairness than one born in a society of equality and right. A child raised in starvation will have a different view of food than one raised in plenty. Our beliefs - even our scientific beliefs - are ineliminably subject to our personal experiences. And that's a good thing, because in this is our capacity, as individuals, and as a society, to learn.

This view should not be confused with the view that it's all a big mystery and that "anything goes."

First of all, from the fact that your knowledge differs from another's, it does not follow that you cannot criticize, or have no grounds for criticizing, another's knowledge. One appeals to one's own experiences, one's own reason, and invites the other to consider similar experiences, to follow a similar reasoning, to explore and to experiment. Because we all have different experiences, our individual experience becomes a basis on which to criticize others' points of view.

And second, this does not grant any sort of license to someone who asserts some proposition on the basis of no experience, no reasoning, whatsoever. Such a person has produced exactly the opposite of knowledge, some set of statements that will not be revised, not even in the face of contradictory experience.

The fact that we each have different experiences, and hence, different knowledge, does not free us from the constraint of basing our knowledge on experience and reasoning, whatever they may be for each of us. That each of us has a slightly different basis for knowledge or belief does not legitimize the employment fo no basis for knowledge or belief.

Relativism is the open-eyed recognition that knowledge and truth are empirically bound, and hence contingent and subject to change, not the uncritical acceptance of any proposition, no matter how poorly formed and supported.

Finally: one may ask, isn't this basis in 'experience' and 'reason' itself a common, non-relative article of knowledge? Yes, one could say such a thing - but swuch a sentence remains true only if it is not examined in any sort of detail. As we push the parameters, as we come to ask for a definition of 'knowledge', 'experience' and 'reason' we find that these concepts, and the logic that relates them, vary from person to person.

The proposition "knowledge is based in experience" itself varies slightly from person to person, and its experession in a language represents an abstraction of the actual belief, as instantiated in different people, but not the belief itself. Each person wears his or her experience differently, and part of the challenge (and the fascination) of life and interaction is to understand this.
