Clough, M.P., & Olson, J.K. (2004). The Nature of Science - Always Part of the Story. The Science Teacher, 71:9, p.28-31.
"Understanding how science works is crucial to scientific literacy because bound up in content and public policy decisions involving science are issues regarding what science is, how knowledge in science comes to be accepted, and what science can and cannot do." p.28
"Science textbooks are notorious for downplaying human influences in research, sanitizing the processes that eventually result in knowledge, and portraying science as simply a lengthy list of conclusions." p.29
This article is also great support for my thinking about using the case files to help teachers address NSES calls for teaching about the nature of science.
