Integrated quantitatively the collective research dealing with the effects of the Intermediate Science Curriculum Study (ISCS) on student performance and attitude. The weighted mean effect size was 0.09, indicating that the performance of ISCS students was 0.09 standard deviations about the performance of students in traditional science courses.…

In 1981 a meta-analysis of research in science education was completed by a team of researchers under the direction of Ronald Anderson at the University of Colorado. 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…

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)
