Reviews the science education literature on (1) the developmental level of adolescents, (2) the relationship between cognitive development and science achievement, and (3) the implications of Piagetian studies to science teaching at the secondary and college level. (MLH)

Discusses science education trends of the last 15 years, new challenges facing science education in a technological society, and the use of planetariums to supplement formal science education. (MLH)

Discusses the difficulty of explaining the concept of entropy, and provides exercises, experiments, and discussions concerning entropy. (MLH)

Described are five physics experiments utilizing inexpensive, readily available materials or materials normally found in a physics laboratory. Included are investigations of electrical charge, sound detection, thermal expansion, doppler effects, and the cycloid. (SL)

Describes a computerized test administration procedure that solves the problem of providing enough different tests for a self-paced chemistry course. The computer randomly generates a new test for each student from a bank of test items, then grades the test, and gives immediate feedback to the student. (MLH)

Presented is a biological game utilized to teach fungi life cycles to secondary biology students. The game is designed to overcome difficulties of correlating schematic drawings with images seen through the microscope, correlating life cycles of fungi and host, and understanding cyclic development of fungi. (SL)

Presented is a review of studies investigating factors affecting climatic changes in the Earth's atmosphere--past, present, and future. Dating methods, particularly the Oxygen 18/16 method, are discussed. (SL)

Secondary and college level students were queried as to which fundamental physics concepts were the most difficult to understand. Concepts reported as most difficult included: difference between mass and weight, magnification, indirection, the idea of fields, and potential difference. (SL)

Presented are justifications for including optics in the science curriculum, an outline of optics instruction as presently presented in English secondary schools, and a review of probable future trends in optics instruction. (SL)

This article provides resource materials teaching astronomy. Included are references to laboratory manuals, articles, films, telescopes, handbooks, and atlases. Each reference is classified as elementary, intermediate or advanced. (SL)

The purpose of this study was to develop an instrument for determining secondary science teachers inquiry attitudes. Forty items were selected to form the Inquiry Science Teaching Strategies instrument. Instrument construct validity and reliability were developed by use of known groups. (SL)

Described is a maternal-fetal model, operated by the student, to teach osmosis-diffusion to biology students. Included are materials needed, assembly instructions, and student operating procedures. (SL)

Presents the entire Advanced Placement Physics C Examination, intended to match the first two terms of a three-to-four term sequence of calculus-based physics courses for physical science or engineering majors. (MLH)

Reviews the English booklet, "Safety in Science Laboratories." Included in the booklet is a discussion of teacher roles in ensuring safety in chemistry and biology laboratories. (SL)

Describes the physics program of the English curriculum project called Computers in the Curriculum. Gives examples of some of the on-line programs that are used in teaching secondary school physics. (MLH)
