This week’s readings filled in some gaps and opened up new ones for some of the broader ideas we have been dealing with. My analysis of Engle and transfer from the situative perspective is written as a separate post because it is fairly lengthy and doesn’t connect with this post much. I also realise not everyone had it as a reading
Beginning with di Sessa (2014), the influence of the History and Philosophy of Science was helpful in characterising the motivations behind the bigger ideas associated with conceptual change. In particular, the role of Kuhn in changing perceptions about the scientific enterprise and his notion of ‘paradigms’ and ‘scientific revolutions’ seems related directly to the idea of accommodations in conceptual change. I don’t find many traces of Tolumin’s idea of the “moving picture” account. I wonder what the implications of this for conceptual change are. An adoption of this perspective seems to undermine how radical an accommodation can be. The conceptual change picture also seems to be in opposition to traditional ideas of the misconceptions approach. Personally, I am not a fan of the phraseology of a ‘mis’conception. The underlying assumption that incorrect beliefs that are held by the student is somehow wrong goes against the role that previously held beliefs play in a theory of conceptual change, where previously held beliefs and the strength of the hold it has on the learner can inhibit or promote assimilation and accommodation of new conceptions. The whole debate on coherence/fragmentation is a useful construct to influence the way we approach instruction for students. However, the study of the history and philosophy of science brings in more questions then answers. For the implications for the classroom, I wonder if the study of scientific communities should really be the source of what determines our theories. There is a significant difference between the community of scientists and the community of learners and the kinds of cognition and activity that happen in these two communities. While science studies does give interesting questions to answer, I am a little cautious about the amount of consideration we should devote as educationalists towards the concerns of how scientific communities work.
By contrast, cognitive apprenticeship seems to get the best from both worlds. A view of cognitive apprenticeship that “extends practice to diverse settings and articulates the common principles” (Gavriel, 2015, p. 111), enables us to consider the common principles of different communities and use them to influence the way we approach education. This may not always be possible however. There are two issues I could identify with this approach. Firstly, is how easily articulation can be achieved. As Gavriel points out, “strategic knowledge is often tacit knowledge” (p.113). Science studies scholars have been trying to analyse the structure of scientific communities and the processes that go behind their decision making from multiple lenses and there aren’t any conclusive answers. Therefore the only way to make the tacit knowledge visible is to immerse the student directly into the community as recreations of the community in the classroom by reducing the activities of the community to a set of implementable principles is difficult to achieve. So when he says teaching methods give students the opportunity to ‘observe, engage in and discover expert strategic knowledge in context’ (p.113), I don’t understand how this would work. Even if we can, in principle, identify the principles of scientific communities (which is in contrast with findings from Nature of Science research which denies that there even exists a set of generalizable principles) this brings us into tension with the principles of the learning community at the center of our classrooms. Gavriel repeatedly talks about the community of practice that must be the center of our focus in the classroom. What community does this involve in the classroom? If we are to follow the “learning communities” train of thinking (p.119), what are the practices that are determined to be good, are they a reflection of the real community of practice and who are the experts? A reconciliation of the principles of the learning community of the classroom and the scientific community may not be all that straight forward.
This suggests that a blended approach (Songer & Kali, 2007) may work well. In general, learning sciences can influence and is influenced by science education. Learning sciences also brings in important practical considerations of what can be achieved in a classroom and the larger social systems of education that play a role in what is admissible in classroom microcultures. The standardisation with the new ‘performance expectations’ that ‘combine a body of knowl- edge with ways of knowing into one blended science knowledge statement’ (Songer & Kali, 2007, p. 567) offers promise in this direction. That being said, these standards should allow for flexibility of local contexts and standards. The notion of socio-scientific issues (SSI) is intriguing as helping provide contextual learning for science classrooms. It is also a useful way to prepare students to become scientifically trained citizenry who can make better decisions in the political and social spheres. This should be a major learning goal for science classrooms and one that (from my exposure at least) has found very little emphasis in science education.
