Compares student achievement and retention scores of secondary school chemistry students who were involved in: (1) learning-for-mastery, (2) personalized system of instruction and (3) control (independent study) modes of remediation work. Higher retention and more objectives were recorded by the learning-for-mastery group. (CP)

Interaction process analysis was used to study the verbal behavior patterns of 10 junior high science teachers. For each teacher, the highest and lowest ability intact classes with whom the teacher worked were studied. Findings revealed that teachers were significantly more indirect and asked more divergent and evaluative questions of the higher…

Investigates the effects of a humanistic teaching-learning environment on the attitudes of preservice teachers and attempts to determine whether activities designed to clarify attitudes are useful in improving attitudes toward science. Participants in the study were 134 preservice teachers. Findings revealed that the humanistic environment was…

Reports the construction and field testing of an electronic device intended to serve as a replacement for Piaget's first chemical task. Validity of the electronic task was established in testing 64 secondary school age students. Results obtained by the chemical and electronic tasks were highly correlated. (CP)

Investigates the relationship between dogmatism (inversely related to open-mindedness) and attitudes toward science of preservice elementary school teachers. Both groups had experienced an inquiry oriented science methods course. Significant negative correlations between dogmatism and attitudes were found for both groups. (CP)

Studies the effects of computer-managed self-paced (CMSP) and teacher-managed group-paced (TMGP) laboratory instruction on the attitudes toward science of ninth-grade students. All students were enrolled in an introduction to chemistry and physics course. Posttests revealed that groups did not differ significantly on achievement measures but the…

Studies elementary school childrens' abilities in (1) measuring and constructing angles, and (2) interpreting and constructing linear graphs as a result of instructional formats. Partitioned into instructional treatments of (1) science, (2) science-mathematics, (3) mathematics, and (4) control were 161 fourth- and fifth-grade children. Mathematics…

The article, with a follow-up section of opposing views, seeks to clarify the role of the Guttman scaling concept with regard to learning hierarchies. (CP)

One thousand twenty-two seventh grade students in country and city schools enrolled in Intermediate Science Curriculum Study (ISCS) programs were the subjects of this study. Differences in learning rates and retention levels were found to be related to pacing, mental ability, and grouping. (CP)

Reports on twelve year-old students instructed in Nuffield Project and in "traditional" classrooms. A division of the subjects into two groups based on intelligence revealed significant differences on classification ability. Interaction effects were also observed. (CP)

Thirteen to fifteen year-old students from Denmark, Sweden, Italy, United States, Austria, Germany, and Great Britain were the subjects on this study of formal thought processes. Socioeconomic status, sex, and school organization provided additional categorization upon which the subjects were divided. Chi square analysis revealed some differences.…

Reports the teaching behaviors of instructors who (1) willfully and (2) under mandate adopted a new earth science syllabus. After a four year time span had elapsed, both groups exhibited similar behaviors. (CP)

The study sought to investigate the effects of available science materials, the physical plant, and the patterns of teacher behavior on the behaviors of fifth-grade students. Some significant treatment as well as aptitude-treatment effects were observed. (CP)

Students (233) in five Israeli high schools were tested to determine the relationship of IQ and achievement, attitudes, and manipulative and observational skills in chemistry. Students indicating a desire to pursue science study were found to differ signicantly their non-science oriented couterparts only on cognitive ability measures. (CP)

Normal adolescents, retarded adolescents, and high ability second-graders were compared on their abilities to master high and low structure science materials. An increase of structure was found to be related to recall for all groups, but to be of particular importance for the retarded adolescents. (CP)
