Constructivism: The view of knowledge that ended philosophy or a theory of learning and instruction?

Background: Constructivism is referred to in two very different ways in education including medical education: to refer to a view of knowledge and to refer to a theory of learning and hence instruction. Summary and Conclusions: This proposal (a) distinguishes between these two usages of constructivism and (b) concludes that constructivism is not a theory of learning and thus as such has little to offer that might be of value to medical education.
