Discusses a study that examined the role of four cognitive factors (formal reasoning ability, prior knowledge, field dependence/independence, and memory capacity) on achievement in chemistry as measured by tests of lab application, chemical calculations, and content knowledge. Reports the significance of prior knowledge and formal reasoning…

Reports on an analysis of secondary school physics teaching with respect to three aspects of curriculum. Indicates that limited but significant relationships exist among intentions, translations, and achievement in the teaching of physics in Canadian secondary schools. (TW)

Reported the development and validation of an integrated model of performance on chemical concept-volumetric analysis. Model was tested on 265 chemistry students in eight schools.Results indicated that for subjects using algorithms without understanding, performance on volumetric analysis problems was not influenced by proportional reasoning…

Investigated was the relation between student ability to translate sentences into equations, equations into sentences, and student performance in formal operational reasoning, proportional reasoning, and introductory-level chemistry. Results indicate that students who lack formal operational skills may experience problems in the translation of…

Surveys the trait anxiety profile and preference concerning types of examinations of preservice science teachers. Reports that the students prefer examinations on understanding and analyzing rather than on knowing and remembering, and that students' anxiety states correlate with the type of examination and sex. (Author)

Reports on a study of Canadian upper secondary science students' achievement of the concept of proportion. Results indicated that, in classes where the proportion content was emphasized by the teachers, higher achievement was demonstrated. (TW)

This study was undertaken to determine whether a biology preparatory course given at an urban community college was helping students to develop the proper skills and background necessary to successfully complete follow-up courses in biology. Data indicated a mathematics score was the main discriminator between pass/fail groups of the preparatory…

Reports on a study designed to investigate how the use of computer assisted instruction (CAI) tutorial programs, incorporating advance organizers and involving various sizes of groups of subjects, would affect achievement scores, retention scores, and rates of learning. (TW)

Examined are the effects of testing on the achievement of students using self-instructional materials to learn science process skills. Results indicated that frequent quizzes did not differentially affect process skill acquisition. (Author/CW)

Examined the influence of selected factors on secondary student's performance in practical chemistry for a sample of students and teachers from 39 Nigerian schools. Student participation in laboratory activities and students attitudes to chemistry were identified as being the most important factors affecting performance in chemistry. (ML)

Studies the effect of intellectual development, degree of field independence, mental capacity, amount of prior genetics knowledge and amount of fluid intelligence on reading comprehension and/or genetics achievement of students enrolled in a nonmajor biology course. Concludes that developmental level was the most consistent predictor of…

Reports on a study which examined the relationship of classroom environment to attitudes toward science and achievement in science among tenth grade biology students. Results indicated that student attitude toward the classroom environment was a signficicant predictor of the student attitude toward science. (TW)

Reports on a study in which two spatial tests were given to science and engineering majors and to students in nursing and agriculture at Purdue University (Indiana). Scores from the tests consistently contributed a small but significant amount of success on measures of performance in chemistry. (TW)

The relationships between mathematical competencies possessed by students and selected student characteristics at the beginning of a semester were examined. The relationship between test scores and the type of mathematics courses taken during the semester students were enrolled in an introductory biology course were also investigated. (Author/CW)

Reports on a study which examined the relationship between spatial ability and performance in organic chemistry. Results indicated that students with high spatial scores did significantly better on questions requiring problem solving skills, as well as on those requiring the mental manipulation of two-dimensional representations of a molecule.
