ABSTRACT

In his well-known essay on the nature of scientific revolutions, Kuhn (1972) theorized that scientific research proceeds through long, relatively stable periods of normal science intermittently punctuated by briefer, more tumultuous times in which new paradigms for research may emerge. He characterized normal science as “research firmly based upon one or more past scientific achievements, achievements that some particular scientific community acknowledges for a time as supplying the foundation for its further practice” (p. 10).
