Discusses solubility interactions of various oils placed on the surface of water and other liquids, explained using the basic forces of gravity, electrical attraction, and quantum mechanics (non-mathematical). Hydrogen and ionic bonding between oleic acid/water is analyzed. An experiment to determine physical properties of the oleic acid molecule…

Suggests teaching a unit on cancer in high school or introductory college courses for non-majors based on surveys of student interest and recommendations to teach prevention/cure of the disease. Discusses smoking, diet, and environmental factors as causes of cancer. Provides several instructional strategies, encouraging student…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including chi-square tests on a microcomputer, an integrated biology game, microscope slides of leaf stomata, culturing soil nematodes, technique for watering locust egg-laying tubes, hazards of biological chemicals (such as benzene, benzidene, calchicine,…

Presents background information, laboratory procedures, classroom materials/activities, and chemistry experiments. Topics include sublimation, electronegativity, electrolysis, experimental aspects of strontianite, halide test, evaluation of present and future computer programs in chemistry, formula building, care of glass/saturated calomel…

Determined effects of including supplementary readings designed to help students (N=233) relate physics to other fields. Both achievement and attitude were measured and significant improvement differences were found for both due to the treatment. Sources for the supplemental readings are cited. (JM)

The Task Force on Graduate Education in Physics (TFGE), an ad hoc committee convened jointly by the American Association of Physics Teachers (AAPT) and the American Physical Society (APS), has studied the current status of graduate education in physics Ph.D. programs, and has made recommendations based on what was found. The findings indicate that…

The aim of this study was to compare the effects of computer-based learning and traditional method on students' attitudes and achievement towards analytical chemistry. Students from Chemistry Education Department at Dokuz Eylul University (D.E.U) were selected randomly and divided into three groups; two experimental (Eg-1 and Eg-2) and a control…

This document reports on a study of two approaches to an analytical chemistry course: (1) a structured active learning approach; and (2) a step-by-step lecture style problem solving approach. The purpose of the study was to assess and compare the outcomes of these approaches. The data consisted of open-ended interviews with students, open-ended…

This report describes a project at Rensselaer Polytechnic Institute (New York) to develop a curriculum that focuses on the social construction and use of science and technology in diverse cultural contexts. The program consists of both a minor and a three-course concentration on cross-cultural studies of science and technology. Courses covered…

Discusses the use of computers for nine different tasks in biological education: information retrieval, data accumulation, data analysis, simulation and systems analysis, decision making, experimental control, course review, computer-managed instruction, and word processing. (PEB)

Describes two-semester sequence of half-credit (two semester hours) seminars offered during spring/fall of the junior/senior years. Junior seminar emphasizes oral communication; introduces students to origins, ideas, and processes of biology; and to how biology influences values/ethics of individuals and society. Senior seminar provides…

Investigated factors accounting for differences in numbers of men/women (N=180) at the doctoral level in science. Examined mathematical, spatial, attitudinal, and personality characteristics of male/female biology/physical science majors and nonmajors. Results (including few differences between males/females in sciences) and implications are…

Compared effectiveness of teacher-demonstration and self-paced modes of teaching concepts and problem-solving skills in college chemistry. Results showed the self-paced mode significantly more effective for teaching concepts and problem-solving skills. Results of an attitude test also showed that most students (N=60) preferred the self-paced…

Provides information on industry-sponsored programs for college faculty and advanced undergraduate students designed to improve polymer science training: these include residency programs for professors available at industrial laboratories, establishment of a Polymer Education Award, newsletter on course materials/sources in polymer science,…

Provided are reviews of a wide spectrum of science and computer science books. Each entry includes review, publication date, and current cost. In addition, entries are coded as to level, subject, type of book, and whether the book is teacher- or student-oriented. (JN)
