Students whose Physical Science Study Committee (PSSC) physics course was supplemented with the PSSC films did not achieve significantly higher scores on the PSSC Achievement Test or the Test on Understanding Science than students who did not see the films, when intelligence and science background were used as covariates. (AL)

Measures whether pre-school children (ages 34 to 65 months) can master concepts of the first five exercises of K-level science--A Process Approach (SAPA) within seven weeks with four lessons of 10 minutes each week. More than 90 percent of the sample of 226 achieved at the 90 percent competency level. (CP)

There were no significant differences in achievement between students using an earth science laboratory block with or without teacher direction. (AL)

Achievement scores of Israeli high school students using Biological Sciences Curriculum Study (BSCS) materials were shown to be significantly higher than those for students using another curriculum. (MLH)

Fifty-nine secondary school physics students were assigned to treatment groups: (1) Project Physics units, (2) Project Physics and verbal learning unit, and (3) a training program in scientific inquiry. Posttest results revealed that, on most aspects of a science inquiry test, treatments 2 and 3 had significantly greater effect on achievement than…

This study was conducted to analyze the classification ability of middle class, culturally diverse, and visually impaired children after instruction in a Science Curriculum Improvement Study (SCIS) unit. The SCIS unit was effective in improving student abilities to classify. (PS)

Describes research undertaken to determine if Science Curriculum Improvement Study (SCIS) can be instrumental in helping children either maintain or develop a positive self-concept. A total of 189 students in grades 3-6 were assigned to treatment and control groups for a period of four and one-half months. Findings did not reveal overall…

Examines how the performance of eight first-grade deaf students was modified by Science- A Process Approach. Applying Chi square analysis to individual performances showed that seven of the eight children achieved significant achievement gain. It is concluded that student learning is not dependent on language ability. (HM)

Utilizes a factorial design with the variables "use or non-use of Biological Sciences Curriculum Study (BSCS) inquiry slides" and "BSCS biology or non-BSCS biology." Eighteen classes of high school biology students were used in the study. Among other findings, groups using BSCS slides were found to be overall superior on…

Cites 124 references to science education research literature and summarizes research on instruction, curriculum, teacher education, developmental studies, teacher characteristics, and instrument development. (AL)

The development and administration of a scientific literacy test designed to measure achievement of the objectives of the Science Curriculum Improvement Study (SCIS) project is described. Students who had completed the six year SCIS curricula were compared with those who had used other science materials. SCIS subjects scored significantly higher…
