NOS is a fuzzy construct; it is neither universal nor stable. There are many attempts to define NOS; for example, McComas, Clough, and Almazroa (1998) provide an overall description of NOS as:
NOS is a fertile hybrid arena, which blends aspects of various social studies of science including the history, sociology, and philosophy of science combined with research from the cognitive sciences such as psychology into a rich description of what science is, how it works, how scientists operate as a social group and how society itself both directs and reacts to scientific endeavours. (p. 4)
From an intensive review of the NOS literature, in-service science teachers' conceptions of NOS can be categorized into four major groups: a) scientific knowledge, b) scientific method, c) scientists' work, and d) scientific enterprise. The next section presents science teachers' conceptions of NOS within these four groups.
