Explains that the result of collision experiments with a linear arrangement of several identical elastic balls cannot be predicted solely from the conservation laws and energy and momentum. Indicates that the system of balls must be capable of dispersion-free energy propagation. (Author/JN)

This is the text of a presentation at a meeting of the Hoosier Association of Science Teachers. Recommendations are given for planning science in the elementary and secondary school to satisfy the Comprehensive Assessment and Program Planning System (CAPPS) mandate in Indiana. (SA)

The purpose of this study was to use parallel measures, in a sample of Israeli classrooms (18 teachers classes) to assess the perception of behavior and adequacy of role performance of self and others. Findings suggest that teacher self-concept is associated with student self-concept and achievement levels. (Author/DS)

Described is a study to determine the long-range impact of the Pennsylvania Nuclear Science Prolect. Findings include that fewer than one-half participants are still teaching the pilot program, that school/teachers who "dropped out" averaged three years from initial involvement, and that student interest and scheduling problems are two…

Discussed are several suggestions for the maintenance of a science self-paced classroom. Topics include the use of computers for student self-assessment, teachers and students roles in the self-paced classroom, and laboratory setup and packaging in the self-paced science laboratory. (Author/DS)

Briefly described are workbooks and other materials focusing on specific aspects of teaching in general (teaching bright pupils, effective questioning, and mixed ability teaching, among others) and science teaching in particular. (JN)

Describes the nature of the neutron and describes how it was discovered. The interaction of the neutron with other nuclear particles is also discussed. (SK)

Describes aspects of the current status of biology teaching at the pre-college level, from an analysis of data collected from three NSF surveys, the NAEP, current textbooks, and other sources. Discusses previous and prospective viewpoints regarding goals of biology education, its curriculum, teachers, laboratory, and contemporary status. (CS)…

Reviews the stages of children's thinking according to Piaget's Theory. Illustrates how a curriculum writer might consider the complexities of a topic and match these to a level of thinking as represented by a school grade level. Outlines the implications of Piagetian levels in the construction of examinations. (GS)

Summarizes the advantages in using the Daedalon Air Table, which supplies compressed air to the pucks instead of the table surface itself. Describes methods for constructing an electronic null detector using a Weston type galvanometer and an integrated circuit operational amplifier. Also describes a redesigned and improved sound-level meter. (CS)

Identified are reasons for discrepancies between desired states and actual practice of problem solving and reflective thinking. Issues discussed include describing the development of problem solving, using problem solving methods in instruction, outcome of developing students' problem solving abilities, and reasonable expectations of attaining the…

Provides evidence to support the conclusion that relationships exist among Piagetian levels of intellectual development, intelligence quotient, content achievement, and inquiry skills in ninth and tenth grade biology students (N=92). (DS)

Describes different ways plastic containers can be recycled for use in the science classroom. Uses of clear, opaque, and translucent plastic products in the science classroom are described. (DS)

An investigation of the relationships among student attributes, styles of teaching, and outcomes in a BSCS-based secondary school biology course is described. Two teaching styles, individual and small group teaching and whole group teaching, were investigated as were student attributes including general ability, personality characteristics, and…

Examines the ability of Australian high school students to recognize definitions of 16 concept words associated with the theme, the nature of matter, and investigates the effect of selected variables on test scores for definitions associated with the theme in question. (HM)
