Efforts to reform undergraduate chemistry laboratory coursework typically focus on the curricula of introductory-level courses, while upper-level courses are bypassed. This study used video-stimulated recall to interview 17 junior- and senior- level chemistry majors after they carried out an experiment as part of a laboratory course. It is assumed…

One of the goals of college-level introductory biology is to establish a foundation of knowledge and skills that can be built upon throughout a biology curriculum. In a reformed introductory biology course, we used iterative model construction as a pedagogical tool to promote students' understanding about conceptual connections, particularly those…

This study investigated the representations of a select group of scientists (n = 10) in a sample of Canadian high school and college textbooks. Drawing on semiotic and cultural-historical activity theoretical frameworks, we conducted two analyses. A coarse-grained, quantitative analysis of the prevalence and structure of these representations…

Presented are the results of an approach to teaching physical chemistry designed to increase student motivation. Student achievement in a course utilizing motivation variables such as self-pacing, no dropping of grades, no pop-tests, and taped lectures, indicated significant gains over a course taught by a traditional approach. (SL)

Examines three issues: the negative nature of today's stereotype of a scientist; the relationship of present stereotypes to course enrollment; and the relationship of the closeness of self-image and stereotype to course enrollment in science. Analysis of semantic differential items reveal differences among science and nonscience college majors.…

Investigated were effects of learning structure on change in preference for science courses. Results indicated that physics students learning in ways they prefer register greater gains in preference for physics than do students in incompatible learning structures. No significant differences were found for students in biology, chemistry, or…

Reports on effects of Individualized Goal Setting (IGS) Audio Tutorial (AT) instruction compared to classic AT instruction and effects of pretesting compared to no pretesting on students' locus of control. Indicates no significant effect on students' locus of control between IGS-AT v AT or between pretesting v no pretesting. (DS)

Investigates the extent to which thinking skills and mathematical competency would predict the course performance of freshman and sophomore science majors enrolled in physics courses. Finds that algebra ability and critical thinking skills were the best predictors. (Author/YP)

Presents data on student performance in a competency-based, multiple-opportunity format physics course, indicating that costs are related to character of examination questions and comprehensional modes of students. Compares costs for single/multiple trial formats, showing that multiple-trial opportunity has lower costs and a higher yield of…

Reports results of a study investigating the ability of college students to solve problems using proportional reasoning. Also discusses implications for consideration of Piagetian cognitive level of students in planning college courses. (CS)

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…

Analysis of an open-ended survey of 144 university and school science educators resulted in identification of six major problem areas: conceptual, organizational, teacher-related, student-related, university-centered, and societal. (Author)

Science education researchers have not used conceptual content of science (with some exceptions) as an important variable in their research. Suggestions are offered as to what kinds of science education research could be done in which conceptual content of science is important. (Author/SK)

Supported by this experimental study was the hypothesis that science process skills of premedical and predental students could be improved by a semester-long course modeled after the AAAS Science - A Process Approach curriculum. Recommendations are made regarding the inclusion of science process skills in college science courses. (CS)

Compares changes in attitudes toward science and open-mindedness in treatment and nontreatment groups of preservice elementary teachers enrolled in an inquiry-oriented methods course and an expository freshman physics course, respectively. Concludes that course design effects a difference in attitude and open-mindedness. (CS)
