Advocates use of Waters Associates Radial Compression Separation System for high performance liquid chromatography. Discusses instrumentation and reagents, outlining procedure for analyzing various foods and discussing typical student data. Points out potential problems due to impurities and pump seal life. Suggests use of ribose as internal…

Proposes a diagrammatic model connecting the cognitive and affective domains of educational objectives, abandoning Krathwohl's hierarchy of affective objectives for one based solely on arousal of interest as a positive dimension. A negative dimension for the hierarchy is also suggested and research evidence supporting the model is given.…

A group of representatives of colleges in western Massachusetts is developing curricula related to nuclear issues. Teaching such issues provides content for promoting liberal arts goals incorporating perspectives of science, engineering and social/political science, and provides opportunities to enlarge students' understanding of the whole domain…

Discusses challenges that should be implemented in chemistry teaching during the 1980s/1990s. These include a focus on social relevance and orientation to student (considering developmental stages, way of thinking, and direct environment). These efforts may change the current negative public image of chemistry. (JN)

Part 1 (SE 533 869) traced history of physics textbooks and discussed texts produced from 1850 to 1870. This part examines aims/methods of physics teaching, textbook style, and cognitive/affective aspects of physics textbooks. Factors that influence the writing and preparation of the texts are also considered. (JM)

Discusses the nature of science as inquiry, differentiating between "science as inquiry" and "teaching/learning by inquiry." Provides evidence of confusion existing among teachers on the notion of inquiry and offers practical suggestions to teacher educators to help teachers better understand inquiry and to use the method in…

Outlines different ways to use microcomputers in science laboratories: (1) as electronic blackboards (simulations, data presentation, number crunching); (2) as universal laboratory instruments (control technology, sound output, time measurement, digital-analog conversions); (3) for educational management; and (4) for computer assisted learning.…

Reports results of a survey of 0- (N=186) and A-level (N=277) chemistry students (before taking their examinations) and their teachers (N=40) to determine their perceptions of how difficult different topics were to learn or teach and to determine if ability, interest, and syllabus were related to perceived difficulty. (DC)

Replicated a study to determine if a sex difference in spatial visualization ability exists among grade six students verging on adolescence and if instruction differentially affects boys/girls at this age. Although instruction significantly affected boys/girls in grades seven to eight, current results do not support the same interaction among…

Describes a course focusing on science, technology, and the nuclear arms race. Two sample homework exercises and course topics are provided. Topics, with lists of questions that might be addressed, focus on nuclear weapons, alternatives to deterrence, and arms control. Approaches to teaching about the nuclear arms race are also provided. (JN)

Student involvement in 24 science classes (grades 8, 9, 10) during instruction involving teacher exposition, exposition with prop, and demonstration was videotaped. Findings indicated that only nine teachers used class demonstrations and that the increased levels of pupil attention and task involvement increased during demonstration lesson…

Active involvement in society-related issues can elevate junior high school students' interest not only in the problem being solved but also in related scientific concepts. Examples of how scientific concepts and society-related issues can be taught in the same class are presented, focusing on genetic engineering, water shortage, and others.…

Discusses the development of and teaching of a physics teacher education course in Iraq. Includes comments on students preparing to become physics teachers and problem/successes associated with the course. (JN)

Describes two workshops for physics teachers in Hispaniola. Workshops demonstrated how mechanics could be developed from planetary motions and how basic mechanics concepts could be introduced through a guided discovery approach. Comments on workshop activities, organization, participant attitudes, and physics curriculum/instruction in Hispaniola…

The Almond model of public opinion can be modified to produce an issue-polarization model of the creation-evolution debate. Suggests that the nonattentive public may hold more potential for expanding the ranks of pro-evolution attentives than for expanding the ranks of those favoring creationism. (JN)
