Individual teams synthesized the extant research using meta-analysis procedures. One of the syntheses showed that the post-Sputnik or "new" science programs on the whole…

One hundred eighty studies of science inservice projects reported in the literature from 1973-1980 were reviewed.

The magnitude of the effect of the…
