Student outcomes were assessed by quantitatively combining results of 57 reported evaluations of three major curriculum programs in elementary school science. Thirty-two percent of the comparisons were statistically significant, favoring activity-based programs; six percent favored control groups. (DH)

Provides evidence indicating that activity-based science programs substantially improve performance in science process/creativity; modestly increase performance on tests of logic, perception, language development, science content, and mathematics; modestly improve attitude toward science and science class; and have pronounced benefits for…

A quantitative synthesis of research findings on the effects of three major activity-based elementary science programs developed with National Science Foundation support was conducted. Controlled evaluation studies of the Elementary Science Study (ESS), Science-A Process Approach (SAPA), or The Science Curriculum Improvement Study (SCIS) were used…
