Presents laboratory procedures, classroom materials/activities, and demonstrations, including: vapor pressure of liquid mixtures and Raoult's law; preparation/analysis of transition metal complexes of ethylammonium chloride; atomic structure display using a ZX81 (includes complete program listing); "pop-up" models of molecules and ions;…

Reviews research conducted between 1966 and 1978 dealing with changing the attitude of preservice elementary teachers toward science and science teachers. Categories of research discussed include elementary science methods courses, micro-teaching, audio-tutorial and self-paced learning, various approaches (humanistic, inquiry, inductive-deductive,…

Investigates and substantiates the effectiveness of the peer teaching approach on the ability of preservice elementary teachers (N=60) to acquire concepts selected from the Elementary Science Methodology Course and on their attitudes towards science and elementary school science. (CS)

Reviews research on demonstration versus small group instruction in four phases (up to 1926, 1926-1946, 1946-1960, and 1960-present), reflecting progressive stages with respect to the development of the investigational techniques used in the studies. (Author/JN)

Results are reported of performance and attitudes of students (N=109) receiving high structure (objectives, reviews, examples, questions, feedback) and students (N=108) receiving low structure (emphasis on content) laboratory manuals and instructions. (SK)

Describes the development of a two-week National Science Foundation (NSF)-funded course at the Virginia Military Institute to promote the lecture demonstration technique. (SK)

Reviews common wild, cultivated, and household plants which may be harmful to humans by causing allergic reactions, dermatitis, physical injury, or internal poisoning. Includes brief descriptions of plants, their potential harm, and some illustrations. (DC)

Presents highlights of Chemical and Engineering News survey of the employment picture for chemical professionals. Focuses on the question of needing a Ph.D.; employment opportunities; salaries; and career planning, including the names and addresses of many employers of chemists and chemical engineers. (SK)

Reports results of a survey of 149 undergraduates (persisters - 73 White, 9 Black) and former undergraduates (nonpersisters - 35 White, 32 Black) indicating how their perceptions of their college environment affected the decision to remain at or leave the Speed Scientific School, University of Louisville. (SK)

Describes a course using the prospect of living in space for motivating students to learn basic physics as well as differences between pure science and technology. Includes course content and a sample final examination. (Author/JN)

Discusses the use of microcomputers as a universal instrument to replace more expensive instrumentation in many traditional labs. Describes the availability of microcomputers as inexpensive educational tools which can be used successfully in labs with minimal requirements on the computer. (SK)

Describes a set of equipment which can be mounted on magnetic chalkboards or other ferromagnetic surfaces, useful for both experiments and demonstrations in mechanics, including center of mass experiments, and force vector experiments using string, spring scales, weights, and pulleys. (SK)

Expresses viewpoints on the status of academic faculty towards the undergraduate education of a biologist. Advocates the acquisition of a general education that will give students the ability to deal successfully with a variety of social and economic problems. (Author/SA)

Describes the Improving Access Through Technology (IATT) project conducted by the Florida Postsecondary Planning Commission which attempts to use technology to increase student access to courses, thereby decreasing time to degree. Identifies student difficulty with math and science courses as a primary cause of lengthening time to degree. (JDI)

Nonscience majors in introductory science courses participated in focus groups to discuss their feelings about the courses. First-day issues were chief on their list as a source of science anxiety. Both general studies students and science-related major students asked for a different approach to the first day of class. Offers first-day strategies…
