What is more, despite the well- established and documented claims as to the centrality of critical social discourse to the generation and validation of scientific knowledge (Longino 1990 ) , students con- tinue to believe that scientists work in isolation and communicate finished products to their colleagues. By the same token, many science teachers continue to deprive students from opportunities to communicate, defend, negotiate, and restructure the ideas they generate in the context of science-based activities. Thus, it could be seen that our work is cut for us even after deciding to forgo—for pragmatic reasons— high-level philosophical, historical, and sociological controversies and limit our- selves to a rather small set of seemingly non-controversial notions about NOS of the sort endorsed in current science education reform documents.
