    • Introduction• This paper defines & examines 3 generations of distance education pedagogy. Unlike earlier classifications on distance education based on the technology used, this analysis focuses on the pedagogy that defines the learning experience encapsulated in the learning design.• “The three generations of cognitive – behaviourist, social constructivist, & connectivist pedagogy are examined, using the familiar community of inquiry model with its focus on social, cognitive, & teaching presence (Garrison, Anderson, & Archer, 2000).• DE like all other technical – social developments, is historically constituted in the thinking & behavioural patterns of those who developed, tested, & implemented what were once novel systems.
    • The 3 Generations of DE Pedagogy COGNITIVE - BEHAVIOURIST Pedagogy of DE SOCIAL - CONSTRUCTIVIST Pedagogy of DE CONNECTIVIST Pedagogy of DE• We will look at Cognitive presence, social presence & teaching presence in and their strengths and weaknesses.
    • 1. COGNITIVE –BEHAVIOURIST Pedagogy of DE• CB pedagogies focus on the way in which learning was predominantly defined, practiced & researched in the later half of the 20th century.• Behavioural learning theory begins with notions of learning which are generally defined as new behaviours or changes in behaviours that are acquired as the result of an individual’s response to stimuli.• Note in this definition the focus on the individual & the necessity for measuring actual behaviours & not attitudes or capacities.For example, Gagne’s (1965) events of instruction proceed through linear &structured phases, including to
    • Gagne’s (1965) events of instruction1. Gain learners’ attention2. Inform learners of objectives3. Stimulate recall of previous information4. Present stimulus material5. Provide learning guidance6. Elicit performance7. Provide feed back8. Assess performance9. Enhance transfer opportunities
    • ’ Cont• Behaviourist notions have been esp. attractive for use in training programs as the learning outcomes associated with training are usu. clearly measured & demonstrated behaviourally. From the behaviourist tradition emerged the cognitive revolution , beginning in the late 1950s (Miller, 2003).• Cognitive pedagogy arose partially in response to a growing need to account for motivation, attitudes and mental barriers that may only be associated or demonstrated through observable behaviours.• Although learning was still conceived of as an individual process, its study expanded from an exclusive focus on behaviour to changes in knowledge or capacity that are stored & recalled in individual memory (Mayer,2001)
    • 2. SOCIAL CONSTRUCTIVIST Pedagogy of DE• SCP developed in conjunction with the development of 2 way communication technologies.• SCP acknowledges the social nature of K+ & of its creation in the minds of individual learners.• Teachers do not merely transmit K+ to be passively consumed by learners; rather, each learner constructs means by which new K+ is both created & integrated with existing K+• Although there are many types of social constructivism (Kanuka & Anderson,1999), all models have more or less common themes, including the importance of
    • Common Themes new K+ as building upon the foundation of previous learning Context is shaping learners’ K+ development Language & other social tools in constructing knowledge Metacognition & evaluation as a means to develop learners’ capacity to assess their own learning, Learning environment as learner centred& stressing the importance of multiple perspectives. K+ needing to be subject to social discussion, validation, & application in real world contexts (Honebein, 1996, Jonassen, 1991; Kanuka & Anderson, 1999).
    • 3. CONNECTIVIST Pedagogy of DE• The 3rd generation of DE pedagogy emerged recently. Canadians George Siemens (2005a&b, 2007) & Steven Downes (2007)have written defining connectivist papers , arguing that learning is the process of building networks of information, contacts & resources that are applied to real problems.• Connectivism was developed in the information age of a networked era ( Castells, 1996) & assumes access to networked technologies.• Connectivism also assumes that that information is plentiful & that the learner’s role is not to memorise or even understand everything, but to have the capacity to find & apply K+ when & where is needed.• Connectivism assumes that much mental processing & problem solving can & should be off-loaded to machines, leading to Siemens’ (2005) claim that “learning may reside in non-human appliance.’• Connectivist models explicitly rely on networked connections between people, digital artifacts, & content which would have been inconceivable as forms of DL were the world Wide Web (www) not available to mediate the process. Thus as we have seen in the case of the earlier generation of DL technology has played a major role in determining the potential pedagogies that may be employed.

    • Strengths & Weaknesses of Cognitive –Behaviourist Models.• To summarize, CB models defined the 1st generation of individualized DE. They maximized access & student freedom, & were capable of scaling to very large numbers at significantly lower costs than traditional edu., as demonstrated by the successful mega universities(Daniel, 1996). However, these advantages were accompanied by the very significant reductions in teaching, social presence & formal models of cognitive presence, reductions that have come under serious challenge since the latter decades of the 20th century. While appropriate when learning objectives are very clear, CB models avoid dealing with the full richness & complexity of humans learning to be, as opposed to learning to do (Vaill, 1996).
    • Strengths & Weakness of constructivist ModelsConstructivist DE pedagogies moved distance learning beyond thenarrow type of K+ transmission that could be encapsulated easily inmedia though to the use of human communication-based learning.Thus, Garrison & others ague that the rich student – student &teacher to student interaction could be viewed as a “post- industrialistea” of DE. However, Annand views the focus on human interaction asplacing limits on accessibility & producing more costly models of DE.Ironically, constructivist models of DE began to share many of theaffordances & liabilities of campus –based education, with potentialfor teacher domination, passive lecture delivery, & restrictions ongeographic & temporal access.
    • Strengths & Weaknesses of Connectivist Approaches• Connectivist approaches used in a formal course setting , where top- down structure is imposed over the bottom –up emergent connections of the network, often heavily rely on the popular net work leaders. Such people occupy highly connected nodes in their networks & can encourage a sufficiently large population to engage so that there is continued activity even when the vast majority does not engage regularly. Even then, learners often yearn for a more controlled environment (Mackness, Mak & Williams,2010)• While a great many speculative & theoretical papers have been written on the potential of connectivism, there is a clear need for a richer means of establishing both networked & personal learning environments that offer control when needed in both pedagogical & organisational terms. The crowd can be a source of wisdom (Surowiecki, 2005) but can equally be a source of stupidity (Carr, 2010), with processes like preferential attachment that are as capable of leading to the Matthew Principle (where the rich get richer & the poor get poorer).
    • Future Generations of DE Pedagogy?• We have seen how different models of teaching & learning have evolved when the technological affordances & climate were right for them. Cognitive –behaviourist pedagogical models arose in a technological environment that constrained communication to the pre-web, one –one & one-many modes; social -constructivism flourished in a Web 1.0, many-many technological context & connectivism is at least partially a product of a networked, Web 2.0 world. It is tempting to speculate what the next generation will bring. Some see Web 3.0 as being the semantic Web, while others include mobility, augmented reality, & location awareness in the mix (Hendler, 2009).• All of these are likely to be important but may not be sufficient to bring about a change of the sorts we have seen in earlier generations of networked systems because the nature & mode of communication, though more refined, will not change much with these emerging technologies. It is already becoming clear that connectivist approaches must become more intelligent in enabling people to connect to & discover sources of K+. Part of that intelligence will come from data mining & analytics, but part will come from the crowd itself.
    • Discussion points• Many educators pride themselves to being pedagogically (as opposed to technology)driven in their teaching and learning designs. However, as McLuhan first argued, technologies also influence & define the usage, in this case the pedagogy instantiated in the learning & instructional design. What did he mean by that?• In an attempt to define a middle ground between either technological or pedagogical determinism, the two are being intertwined in a dance; the technology sets the beat & creates music, while the pedagogy defines the moves (Dron & Anderson, 2009). What did they mean by that?• They further went on by stating that “to some extent our pedagogical processes may themselves be viewed as technologies move (Dron & Anderson, 2009).• The availability of technologies to support different models of learning strongly influences what kinds of models can be developed; if there were no means of two-way communication, what would it be like?
    • Conclusion• Distance education has evolved through many technologies and at least three generations of pedagogy, as described in this paper. No single generation has provided all the answers, and each has built on foundations provided by its predecessors rather than replacing the earlier prototype (Ireland, 2007).• For each mode of engagement, different types of knowledge, learning, and contexts must be applied and demand that distance educators and students be skilled and informed to select the best mix(es) of both pedagogy and technology. Although the prime actors in all three generations remain the same—teacher, student, and content—the development of relationships among these three increases from the critical role of student–student interaction in constructivism to the student–content interrelationship celebrated in connectivist pedagogies, with their focus on persistent networks and user-generated content.• The Web sites, books, tutorial materials, videos, and so on, from which a learner may learn, all work more or less effectively according to how well they enable the learner to gain knowledge. Even when learning relies on entirely social interactions, the various parties involved may communicate knowledge more or less effectively. It is clear that whether the learner is at the centre or part of a learning community or learning network, learning effectiveness can be greatly enhanced by applying, at a detailed level, an understanding of how people can learn more effectively: Cognitivist, behaviourist, constructivist, and connectivist theories each play an important role.
