Studied performance of 15 low-socio-economic-status 14 year olds in learning controlled-experiment design and evaluation, and indicated that experimental subjects significantly outperformed matched controls. (CC)

This study was conducted to determine if secondary school science teachers differed in personality factors from secondary non-science teachers. Scores of 80 science and 35 randomly selected non-science teachers were collected on the 16 PF Questionnaire. (PS)

Revised the Reed activities checklist to obtain an equal number of active and passive activities and an equal number of items representing interest in each field. Factor analysis of the present list among 2,137 seventh and eighth grade students supported the conclusion that science interest is not unindimensional. (CC)

Studied effects of participation in Science - A Process Approach activities through an experimental-control, pretest-posttest research design. Data analyses of 113 kindergarten children enrolled in four classes of an inner-city school showed that transmitting skills were enhanced with increasing beginning reading ability. (CC)

Physical science curriculum materials were developed for below-average students based on guidelines for science teaching. These materials were tested in three ninth and tenth grade classrooms. Results showed significant improvement in students' attitudes toward the science class and laboratory. (PS)

Describes a method with data analyzed from two lessons on the quantitative assessment of content structure in classroom dialogue. Kinetic structure analysis was used and the fundamental coefficient of structure was calculated for each lesson. The method should provide new directions for looking at verbal interaction in classrooms. (PS)

Proposes a model that implies that enrollments in science classes will increase if the grade penalty in science subjects is less severe. Students' decisions are based on rough comparisons between their grades in other subjects and early science courses. Student records from 27 schools were analyzed for correlations between many variables. Results…

Presents notion that low science enrollments in high schools are partially related to the severity of grading practices used by science teachers. A model is discussed which assumes that students compare the science grades with grades received in other subjects. Research methodology is suggested. (PS)

Describes the rationale, construction, administration, and analysis of an externally set examination for BSCS students at the end of the twelfth grade. Three areas covered in the examination were: functional information, identification and application of principles, and contributory mode understanding of the principles of biological enquiry.…

Some early results are reported of a study to examine trends of student evaluations in college level physics courses. Higher ratings were consistently given for higher level courses. (PS)

Using an instrument developed by the authors, 60 professors, 30 science and 30 humanities, rated each of 10 values on 12 criteria scales. Results showed significant differences in weightings placed by the two groups on eight values. (PS)

Research reports published in a science education research journal were examined to calculate the probability of rejecting true null hypotheses. Recommendations for improving analyses and research in science education are provided. (PS)

Study compared patterns of teachers' verbal explanations of physics problems with patterns of scientific explanations evident in philosophical literature. Fourteen high school physics teachers were observed in micro-teaching situations and all verbal utterances analyzed. Results showed that constructs and lecturing are the most frequently used…

Effects of performance objectives on achievement of black inner city pupils were studied. Two groups of trained and untrained teachers in preparing performance objectives were formed. Results showed positive effects of teachers trained in the use of performance objectives. (PS)

There was no significant difference in attitudes toward biology between high-ability grade nine biology students exposed to 20 randomly selected Invitations to Enquiry'' and similar students whose course did not include invitations. There is some suggestion that more difficult Invitations'' later in the course may have arrested a general decline…
