Discusses: (1) feature of videodisc technology which make it a versatile educational tool; (2) availability of videodiscs for teaching physics and astronomy; and (3) example of the ways these videodiscs can be used in instructional settings. Tables listing physics and astronomy videodiscs (title, author, source, cost, and abstract) are included.…

Presents information on the perceptions of students (from third, seventh, and eleventh grade) and young adults concerning science classes, their science teachers, and the value of science content. Includes data from the Third Assessment of Science (1977), National Science Supervisors Association Study (1982), and National Science Teacher…

Discussed contributions to the field of astronomy made by ancient Egyptians. Provides examples of how some of the observations made were applied to science. The use of geometry is illustrated by several calculations of celestial alignment. (TW)

Describes five ways that high school students explain a chemical change. Discusses the differences in conceptual understanding of the students based upon their responses to questions about simple reactions. Presents additional classifications of conceptions of chemical reactions done by other researchers. (TW)

Examines the importance of levels of questioning and types of feedback in designing courseware for computer-based education. Test results are analyzed for four groups of high school students who completed different versions of a computer-based science lesson, and recommendations for future research are given. (Author/LRW)

Addresses some concerns about the safety of handicapped students in school science laboratories, along with some of the litigating factors involved in not addressing those concerns. Offers some general suggestions for teachers in working with handicapped students, and describes specific laboratory teaching approaches for students with different…

Describes a high school chemistry student's research project in which limonene was isolated from the oil of lemons and oranges. Outlines the students' tests on the use of this chemical as an insecticide. Discusses possible extensions of the exercises based on questions generated by the students. (TW)

High school counselors in Virginia were surveyed on their recommendations for academic programs in science and mathematics for fictitiously named male and female students at different levels of academic achievement. The counselors were apparently not influenced by the sex of students. (MNS)

Addresses the need to present beginning chemistry students with a variety of experiences dealing with chemical reactions to develop the individual student's concept of these processes. Presents information and experiments dealing with the heat effect of chemical reactions. Includes a discussion on exothermic and endothermic processes in laboratory…

Addresses the introduction of low cost equipment into high school and college physical science classes. Examines the properties of an "ideal" operational amplifier and discusses how it might be used under saturated and non-saturated conditions. Notes the action of a "real" operational amplifier. (TW)

Reviews three software programs: "Fraction Fuel-Up"; "Explorations in Chemistry"; and "Locus." Includes information on: instructional orientation, educational level, systems package, publisher, program description, strengths and weaknesses, applications, and recommendations for improvement. Includes a general critique statement in the summary…

Discusses a study which examined the interpretive process used by high school chemistry teachers in translating curriculum materials into classroom practice. Results indicate that differences exist among teachers but that commonalities are greater. Explains the functional paradigm concept and its value for the interpretation of curriculum…

Determined that an instructional unit on laboratory safety could increase student safety knowledge and reduce the number of unsafe behaviors. A list of unsafe behaviors which were observed with the 333 students is included. A recommendation that positive attitudes toward safety be developed is given. (DH)

Provides an overview of the educational program of the Seychelles and focuses on an evaluation of the final phase (P7-P9) of the nine-year school program. Reports how findings from content analyses of materials, teacher and student interviews, and student test results were used to develop the new Seychelles Integrated Science program. (ML)

Describes typical instructional applications of computers. Areas considered include: (1) instructional simulations and animations; (2) data analysis; (3) drill and practice; (4) student evaluation; (5) development of computer models and simulations; (6) biometrics or biostatistics; and (7) direct data acquisition and analysis.
