Exploring connections between Education and Information Science literature

As research through Inquiry based learning, problem/project based learning, education & cognitive learning theories has progressed I am finding that the topic is getting larger rather than smaller. It is interesting to see how ideas from Piaget, Vygotsky, Bruner, and Bloom are central to the ideas presented in IBL literature. I am curious as to why we do not see these works referenced in informaiton science literature. Many of their theories (Vygotsky & Bruner in particular) show an emphasis on social & interactive development that is central to Chatman & Dervin’s information seeking theories. Favorite quote so far. . ."To perceive is to categorize, to conceptualize is to categorize, to learn is to form categories, to make decisions is to categorize"- Bruner as cited by Anderson (http://facultyweb.cortland.edu/~andersmd/cog/bruner.html). This idea, also stated by Vygotsky in his discussion of the adaptation of the individual to they symbolic systems of society gets back to the work of Lakoff, Johnson, and Patrick Wilson and yet, looking through reference lists, the two areas never seem to interact. The concept that learning is the application (or adaptation) of organizational & symbolic systems on experience (Bruner/Vygotsky) seems to be the exact ideas expressed by Lakoff/Wilson . . .Am I missing some connection here?
