Evaluates junior high students' understanding of certain aspects of the particle model of matter using a Piaget-type interview. Approximately 70 students from grades seven, eight, and nine in several midwestern schools in the U.S. were interviewed. (HM)

Describes the Coriolis machine, and explains its use to study the inertial motion of a particle moving with constant velocity, from a rotating frame of reference. (GA)

Describes the latest developments in the Scottish Integrated Science Course designed for all pupils in the 12-14 age group during the first two years of secondary education in Scotland. Through the assistance of many teachers, a completely new set of materials for pupils and teachers has been produced. (HM)

Presents a British biology course for the O-level which aims to promote the understanding of broad biological principles through an environmental approach. Results of proper assessment and overall examination performance are also revealed. (HM)

Presents environmental education field exercises which illustrate the influence of urbanization on land surface. A practical example with the appropriate data analysis is included. (SL)

Presents student and teacher evaluations of the LAMP unit "Paints and Dyes." The units are designed for low motivated secondary school students. Copies of the objectives and the evaluation instruments are included with the article. (CP)

Describes a session at the 1978 National Congress on Aerospace Education in which participants constructed devices and instructional materials. (CP)

Dispels the notion that exciting and imaginative science is the result of packaged curriculum materials or teaching methods. Instead, the necessity to follow students' inclinations and desires rather than rigid study guides is advocated. (CP)

Discusses the possibilities of space providing occupations as a new frontier in the 1990's. (SL)

Describes a computer-assisted chemistry program which allows for individualization and which utilizes BASIC computer programming. (SL)

An experiment is described which uses lead sulfide to illustrate the concept of definite proportions as well as the union of atoms to form compounds. This experiment has been successfully used with ninth graders. The advantages of this experimental procedure over available alternatives are listed. (MR)

Suggests criteria to be used in the selection of a standardized test. Analyzes 12 standardized middle school science tests according to the percentage of questions in each of Bloom's categories. (CP)

Reviews pertinent science education literature on comparative studies of individualized self-pared instruction with conventional teacher-centered, lecture-demonstration instruction. (CP)

Provides a review of research on scientific reasoning in persons between ages 14 and 18. For the application, the ability to separate variables or use the concept of "all other things being equal" is termed scientific reasoning. Over 50 studies are referenced. (CP)

Reviews techniques available for measuring student skills with the processes of science at the elementary and secondary levels. (SL)
