Monitoring student performance on microcomputer drill and practice programs over time provides evidence that students learn from the programs at different rates and that programs differ in the rates at which they impart learning to students. Implications of these and other findings for science teaching are addressed. (JN)

Investigated: (1) immediate and continuing benefits associated with using microcomputer-assisted testing with 42 biology students; (2) types of students benefiting from microcomputer-administered diagnostic testing; and (3) the feasibility of microcomputer-administered diagnostic testing. One finding is that such testing positively influences…

Compared selected teacher beliefs and verbal behaviors among secondary science and mathematics teachers. Teacher beliefs included teacher responsibility for student success and failure. Comparisons were made for these categories of teachers: (1) science/mathematics; (2) junior/senior high; (3) teachers of advanced/basic courses; and (4)…

As an alternative guide to science teaching, a generalized theory of scientific observation defined in terms of human intentions and purposes is offered. The generalized theory, while based on assumptions different from those of the science education theory, can still account for the plausibility of many aspects of that theory. (JN)

The effects of controversy and concurrence seeking and participation in age-homogeneous and age-heterogeneous cooperative learning groups were compared on achievement, achievement motivation, perspective-taking accuracy, and interpersonal attraction. In addition, the interaction among students (N=112 fourth-, fifth-, and sixth-graders) within the…

Examined 297 students in biology classes where girls are encouraged in science, focusing on actual science experiences, masculine/feminine tasks, extracurricular science activities, feelings about science classes, research funding, and science career interest. Suggests that equal experiences within science classrooms do not overcome advantages…

Investigated visuo-spatial ability of a control group and an experimental group (receiving 30 minutes of interaction each week) in undergraduate college biology. Results for the subjects (N=84) indicate that visuo-spatial aptitude can be enhanced through teaching. (Descriptions of interaction sessions and explanations of tasks are included.) (DH)

A matching model of instruction on independent variables of need level, cognitive style, and locus of control resulted in improved attitude toward science in general for ninth-grade physical science students (N=574). Although achievement and other attitudes did not improve, empirical evidence suggests some matching is better than none. (DH)

Developed and validated a learning hierarchy for the concept "food web" (the hierarchy consisting of nine skill areas). Also investigated the misconceptions of 200 students related to these nine areas. Suggestions for applying the hierarchy model to remediation and resolution of the misconceptions are provided. (DH)

Determined the effects of reasoning, use of models during testing, and sex type on posttest achievement in chemical bonding under controlled instruction. Indicates that chemistry students' (N=84) reasoning capabilities influenced performance; other variables were not significant. Other conclusions are noted and discussed. (DH)

Results of interviews with high school chemistry students (N=14) during equation-solving sessions indicate that those who were able to construct diagrams consistent with notation of their balanced equation possessed good concepts of subscript and the balancing rule. Implications for chemistry teaching are discussed. (DH)

Specific modes of formal reasoning and measurements of principled moral reasoning ability were obtained from 99 10th-grade students. Hierarchical relationships were found amoung variables with combinatorial and correlational reasoning accounting for 22 percent of the variance in principled moral reasoning. Theoretical and educational implications…

This study compared the classroom environments as perceived by fourth-grade, seventh-grade and high school boys and girls in classes taught by males and females to determine if any perceptual differences existed. The analyses showed no differences for fourth-grade students, one for seventh-grade students, and three for high school students.…

Analyzed and classified were Individualized Science Instruction System (ISIS) minicourse performance objectives and criterion-referenced test items according to Bloom's cognitive "Taxonomy" to determine levels of cognition emphasized. The findings indicate that ISIS minicourse test objectives are written primarily at the knowledge and…

Examined the effect of matching learners' cognitive styles with science learning activities on changes in science knowledge and attitudes. Fifty-six elementary education majors, identified as Sensing Feeling types on the Myers-Briggs Type Indicator, participated in the study. Results revealed no significant differences between matched and…
