Educational Pedagogies for Learning in 21st Century



Reflecting on the different educational pedagogies and reviewing each one in relation to technology for online learning and teaching I would be taking different aspects of each one into consideration. The first consideration was the two metaphor approach discussed by Sfard (1998). The two metaphors explain clearly how learning is viewed as two opposing ideologies which I believe is limiting since there is no suggestion of a connection / continuum between the two. Sfard (1998) herself suggests that a sound theory of learning will consider both the metaphors to explain effectively how learning takes place. Expanding the two metaphors to three paradigms as suggested by Greeno, Collins & Resnick (1996) allows us to include the three main issues related to learning – as activity, as achieving understanding and as social practice. The different theories of learning once more can be placed in one paradigm or the other. The application of theories is, however, closely linked to what is being learnt. This means that a single theory and therefore a single paradigm cannot be used in all manner of learning as it becomes difficult to achieve holistic learning. This is also reflected in the way in which people learn.

I think, that the experiential learning theory can provide the holistic approach that both Sfard’s (1998) metaphors and Greeno, Collins & Resnick’s (1996) three paradigms are lacking. It takes into consideration the activity, the knowledge and application of that back into social practice. The cyclical process described by Kolb and Fry (1975) shows clearly how these aspects fit together. None of them have an advantage over others as all parts of the process have equal importance. The other advantage of the cyclical process is that one can enter into the learning cycle at any point. This allows all learning styles to be incorporated into the learning process.  For example, an activist learner can start the process of learning at the point of carrying out an activity / having a concrete experience, while a theorist learner can start the cycle at the point of reading literature / learning about the relevant theories and continuing the cycle. The cycle also takes into account the aspect of linking the theory to practice as knowledge has to be used in reality. This link is provided by the review / reflection part of the learning process.

The process of  reflection is also a cycle and takes into account the situational context and social aspect of the activity that is the focus of reflection. (Schon, 1983, 1987) The two cycles linked together forms the appropriate pedagogy for learning in any situation. This understanding can explain how learning takes place for individuals. There is a transaction of meaning that happens during reflection. One has to review the situation in relation to the social context and existing understanding. The concepts that are central to the situation are explored and reading of relevant literature is carried out. Then the individual attempts to return to the situation and sees how the new knowledge can be incorporated to give a better understanding of the situation and thus improve practice. Thus, an internal dialogue takes place when the individual tries to integrate old and new knowledge.

However, we need to remember that in the educational context learning takes place in groups and not individually. Learning takes place in the educational institution or in the workplace where other people are involved. In such situations the individual approach to learning would not be entirely effective. We need to expand this experiential learning and reflection to take into account the impact of the group (colleagues or peers) on the process of learning. This collaborative approach to using experiential learning and reflection can be seen within Wenger’s (1999) community of practice and social learning theories where the group can participate in every stage of the process of the experiential learning cycle. The learning within this kind of collaborative approach takes place through sharing, scaffolding and negotiating meaning. Learning is taking place also through thinking and reflecting on others contribution in the discussion. Collaboration provides a much richer environment for the learners as there is collective knowledge to reflect on rather than individual. Here also, a dialogue is taking place to transact the meaning, but it is now external to the individual. Individuals learn from and with each other in the group. This takes into account some elements of the socio-cultural and constructivist theories. There is room for individual reflection within this process and so makes this combination of individual and collective learning an attractive pedagogy of education. This collaboration and scaffolding is also embedded in the different argument theories (see earlier blogs). While all of the theories seem to explain the process and parts of a logical argument and its outcome, Progressive Inquiry actually gives the process a structure and explains how the concept can be used in educational context. It is comparable to the recently popularised Problem / Inquiry Based Learning approach to curriculum development. This approach can also be linked to two of Mason’s (2001) framework for online.

When applied to use of technology in learning and teaching, we can still see the usefulness of both aspects. Thus, despite the move of the education from classroom to online, the ideology of learning with and from the group is still important. The courses online can be developed such that they encourage learning and this can be both individual and collaborative. The software for encouraging learning is designed to enhance and support the process of learning by developing critical thinking skills.  The design can be focused on encouraging experiential learning and reflection and / or collaborative learning via a Progressive Inquiry approach. Context, question and brainstorming aspects of PI can take place in a synchronous session, critical evaluation, deepening and structuring can be carried out asynchronously to allow for the reading and reflection that is required of the members of the community. The concluding of the negotiation of meaning can be done synchronously as this brings the group together to complete the discussion in real time. Finally, the shared understanding can be carried out asynchronously to adjust the changes to the knowledge of the group. The asynchronous online learning allows for individual reflection and learning before sharing that knowledge with the group. The synchronous learning online tends to mimic the face to face classroom approach which needs to be adapted to a different medium. Therefore, the software for synchronous online learning, whether linear text display of discussion or graphic and spatial display of discussion, needs to encourage collaborative approach so that understanding of the concept under discussion can be constructed by the group members.

Argument Theories - Knowledge Building and Progressive Inquiry



Similar to Baker’s learning mechanisms in online dialogue, Scardamalia and Bereiter (1992) developed a framework for learning and knowledge construction through online social dialogues called knowledge building. ‘Knowledge building takes place in social settings or communities which are similar to scientific research communities and operate based on constructivist principles (knowledge is a human construction and not something that is to be revealed or transmitted), sociocultural activity (as the medium through which knowledge construction takes place) and apprenticeship (skills of young scientists are acquired by working with a more mature scientist).’ (De Laat & Wegerif 2007, pp 9) Scardamalia and Bereiter developed a networked learning environment called CSILE (computer-supported intentional learning environments) that embedded the following knowledge building principles to support online dialogue (Scardamalia and Bereiter, 1992, p. 44-46):

• Objectification - Treat knowledge as objects that can be criticized, modified, compared and related, and regarded from different viewpoints, in different contexts.
• Progress - Knowledge building should lead somewhere and progress should be noticeable to the students.
• Synthesis - Encourage higher order representations and integrations of knowledge rather than the proliferation of loosely connected items.
• Consequence - Something nice should happen to the students as a consequence of knowledge building activities.
• Contribution - Contributions to the communal database should be visible, not exclusively in terms of their intrinsic worth, but also to their contribution to advancement of the group’s knowledge.
• Cross-fertilization - Maximize opportunities for the students to come into contact with related ideas, kindred spirits, and useful information, unrestricted by boundaries of space and category.
• Social - There should be continuity between work in CSILE and other curricular activities.

The central activity of knowledge building is aimed at progressive discourse associated to advancement of knowledge. Hakkarainen (1998) developed a pedagogical model called Progressive Inquiry (PI) to facilitate this process. PI engages members of a knowledge building community in a step-by-step process of question and explanation-driven inquiry (Muukonen, Hakkarainen & Lakkala, 1999). This is similar to the problem based / inquiry based learning approach which underlies many curricula in present day higher education. PI consists of the following elements (Muukonen, Hakkarainen & Lakkala, 1999):
  • Context: The participants in a PI structured activity begin by creating the context. In order to explore the problem more deeply, the participants have to become familiar with it. A context is first created in order to clarify why the issues in question are relevant and worthwhile to investigate. In this way the community develops a body of understanding that serves as an anchor for the formulation of the problem statement or research question.
  • Questions: Scientific inquiry, which is used as the basis of this model, can be seen as a problem solving process. Initial questions guide and direct the search for information.
  • Brainstorm: Once the participants have agreed on an initial research question, the members are invited to construct their own interpretation. In this phase the participants have a brainstorm session to present and construct personal working theories. The participants are stimulated to use prior knowledge to offer an initial explanation for the problem. In this phase a first ‘knowledge base’ of the community’s understanding of the problem has been created. This knowledge base (or inventory of distributed expertise) needs to be evaluated.
  • Critical evaluation: Evaluation is an important next step to assess advancement in the theories or explanations being offered. Through an evaluation of whether, and how well, the working theories explain the chosen problems, the community can assess the strengths and weaknesses of different explanations and identify contradictory explanations and gaps in the knowledge.
  • Deepening: The next step is to search for deepening knowledge. Considerable advancement of the inquiry cannot be made without obtaining further, new information. By re-examining prior problem statements or working theories, with the help of new information, the community may become aware of their inadequate presumptions. New information may help them to reconstruct their conceptual understanding of the problem.
  • Structuring: Progressive Inquiry is a process of further refinement and structuring of the collective understanding of the problem. Initially the community had a broad conception of the problem that lead to general questions. After making an inventory of prior knowledge, and searching for new information, more specific questions could emerge. Advancement of the inquiry is obtained by developing a chain of deepening questions.
  • Concluding: In the last phase, the community, by finding answers to subordinate questions, approaches step-by-step toward a fuller answering of the original question or problem statement.
  • Shared Understanding: This stage is the fundamental element of PI activity. Knowledge building is a social process aimed at advancing knowledge through active engagement in the learning activity by all members of the community. By explicitly working towards a shared understanding of the problem at each stage during their dialogue the members are able to construct knowledge collaboratively and in doing so advance the knowledge of the individual as well the entire community.

This understanding of the PI is useful in that it could be the process by which learning can be supported using the online tools. In effect there could be separate synchronous discussions for each stage or some of the stages of the PI process. This ensures that the synchronous tools are used effectively to allow for furthering the learning from the discussion as part of the overall learning process rather than used in isolation.
