In the early days of classroom research, a great number of studies were conducted but unfortunately yielded either insignificant or contradictory results. As Medley (1979) puts it, "to borrow a phrase Charles Silberman once used in a similar context, the teacher educator who examines the research is likely to conclude that there is less there than meets the eye" (p.16). But in the past twenty years, and especially the past ten years, the research on teaching has been fruitful and can be of great benefit to teachers and teacher educators.
