Despite its flaws and frequent abuses, PowerPoint can add significant value to a talk when it is not misused.

One of my dirty little secrets is that without it, I am likely to lose my place while speaking.

But there’s another reason to include it. PowerPoint can be a great supplement to your talk. I use it to illustrate the stories I tell in the same way photos enhance the articles and blogs I publish.

I’m a minimalist on text. If I use bullet points, there are usually only one-to-five words per bullet and the font is large enough to read from the back of the room. When I click to a new slide, I pause and let people view it for a moment.

It is notable that social-constructivist models only began to gain a foothold in distance education when the technologies of many-to-many communication became widely available, enabled first by email and bulletin boards, and later through the World Wide Web and mobile technologies. While such models had been waiting in the wings for distance education since Dewey or earlier, their widespread use and adoption was dependent on the widespread availability of workable supporting technologies.

It remains challenging to apply learning where it can blossom into application and thus demonstrate true understanding.

Teaching presence extends beyond facilitation of learning to choosing and constructing educational interventions and to providing direct instruction when required.

teaching presence in constructivist pedagogical models focuses on guiding and evaluating authentic tasks performed in realistic contexts.

Ironically, constructivist models of distance education began to share many of the affordances and liabilities of campus-based education, with potential for teacher domination, passive lecture delivery, and restrictions on geographic and temporal access.

Connectivist learning focuses on building and maintaining networked connections that are current and flexible enough to be applied to existing and emergent problems. Connectivism also assumes that information is plentiful and that the learner’s role is not to memorize or even understand everything, but to have the capacity to find and apply knowledge when and where it is needed. Connectivism assumes that much mental processing and problem solving can and should be off-loaded to machines

Connectivist cognitive presence begins with the assumption that learners have access to powerful networks and, as importantly, are literate and confident enough to exploit these networks in completing learning tasks. Thus, the first task of connectivist education involves exposing students to networks and providing opportunities for them to gain a sense of self-efficacy in networked-based cognitive skills and the process of developing their own net presence.

The artifacts of connectivist learning are usually open, accessible, and persistent. Thus, distance education interaction moves beyond individual consultations with faculty (CB pedagogy) and beyond the group interactions and constraints of the learning management systems associated with constructivist distance-education pedagogy.  Cognitive presence is enriched by peripheral and emergent interactions on networks, in which alumni, practicing professionals, and other teachers are able to observe, comment upon, and contribute to connectivist learning.

Connectivist pedagogy stresses the development of social presence and social capital through the creation and sustenance of networks of current and past learners and of those with knowledge relevant to the learning goals. Unlike group learning, in which social presence is often created by expectation and marking for participation in activities confined to institutional time frames, social presence on networks tends to be busy as topics rise and fall in interest.

Connectivist learning is also enhanced by the stigmergic knowledge of others and the signs that they leave as they navigate through learning activities. The activities, choices, and artifacts left by previous users are mined through network analytics and presented as guideposts and paths to knowledge that new users can follow (Dron, 2006). In this way, the combination of traces of people’s actions and activities generate an emergent collective, which may be seen as a distinctive individual in itself, both greater and lesser than the sum of its parts: it is a socially constituted entity that is, despite this, soulless, a reflection of the group mind that influences but does not engage in dialogue (Dron & Anderson, 2009).

As in constructivist learning, teaching presence is created by the building of learning paths and by design and support of interactions, such that learners make connections with existing and new knowledge resources. Unlike earlier pedagogies, the teacher is not solely responsible for defining, generating, or assigning content. Rather, learners and teacher collaborate to create the content of study, and in the process re-create that content for future use by others. Assessment in connectivist pedagogy combines self-reflection with teacher assessment of the contributions to the current and future courses.

Teaching presence in connectivist learning environments also focuses on teaching by example.

A final stress to teaching presence is the challenge presented by rapidly changing technologies. No one is current on all learning and communications applications, but teachers are often less competent and have less self-efficacy; thus, connectivist learning includes learners teaching teachers and each other, in conjunction with teachers aiding the connectivist learning of all.

Learning in connectivist space is, paradoxically, plagued by a lack of connection.

In connectivist space, structure is unevenly distributed and often emergent, with that emergence seldom leading to structure that is optimally efficient for achieving learning goals.

Cognitive-behaviourist models are most notably theories of teaching and social–constructivist models are more notably theories of learning, but both still translate well into methods and processes for teaching. Connectivist models are more distinctly theories of knowledge, which makes them hard to translate into ways to learn and harder still to translate into ways to teach. Indeed, the notion of a teacher is almost foreign to the connectivist worldview, except perhaps as a role model and fellow node (perhaps one more heavily weighted or connected) in a network.

As concerns about privacy mount and we come to adopt a more nuanced approach to connections and trust, our networks are bound to become more variegated and specialized. It is already becoming clear that connectivist approaches must become more intelligent in enabling people to connect to and discover sources of knowledge.

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 popular community-of-inquiry model, with its focus on building and sustaining cognitive, social, and teaching presence, can be a useful heuristic in selecting appropriate pedagogies.

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.

As the term community has become an ambiguous buzzword, the concept has become synonymous with online discussion boards and chat rooms. When put into a learning context, however, community can be a vehicle for connecting people to other people’s stories and experiences, as well as mentoring, all of which result in accelerated learning and the sharing of tacit knowledge within an organization.
