The Comparative Effects of Three Seventh-Grade Science Programs with Different Laboratory Materials.
Stronck, David R.
Presented are the procedures, results, and conclusions of an experimental study designed to (1) determine the effects of the 1967-68 science inservice program of the Archdiocese of San Francisco, and (2) compare the effects of three seventh-grade science programs utilizing different laboratory materials. The experimental group consisted of 499 seventh-grade students in seven parochial schools in San Francisco. These students used the text and laboratory materials supplied through the inservice program. Their performance on the Portland Science Test was contrasted with the performance of other seventh grade students in two control groups. The first control group consisted of 475 seventh-grade students of the previous year in the same schools. The second control group consisted of 127 seventh-grade students of the academic year 1967-68 in four parochial schools located away from San Francisco by matching the socio-economic level, the preparation of the teachers, and the use of the text. Major findings of the study were (1) that there were significant differences between the mean scores in 1968 and 1967, (2) that, in every instance, the mean score achieved in 1968 was lower than the score in 1967, and (3) that there were no significant differences between the mean scores of the experimental group and the mean scores of the second control group.
