The first article in this publication concerns radio-telemetry temperature studies of homoiotherms and poikilotherms. Radio telemetry reduces the problems related to demonstrating the differences between "warm-blooded" and "cold-blooded" animals; results may be plotted graphically, compared and used to generate classroom…

Israeli tenth-grade students completed a chemistry laboratory course by either performing the experiments or by viewing films of the experiments. Among the results of an attitude test given to both groups was that students find personalized laboratory more effective than films in promoting their interest in chemistry. (MLH)

This study developed and validated an inventory to measure students' attitudes toward and interest in laboratory work in high school chemistry. Factor analysis provided some evidence that interest in and attitude towards laboratory work in high school chemistry is not unidimensional, as it has been assumed to be. (BT)

The adaptation of the Projective Tests of Attitudes (PTOA) for use with adults is described. The revised test forms are appended. (CR)

Studies the effects of computer-managed self-paced (CMSP) and teacher-managed group-paced (TMGP) laboratory instruction on the attitudes toward science of ninth-grade students. All students were enrolled in an introduction to chemistry and physics course. Posttests revealed that groups did not differ significantly on achievement measures but the…

Contrasts spontaneous and reflective knowledge integration instruction delivered using a computer learning environment to enhance understanding of displaced volume. Distinguishes the impact of instruction on students who believed scientific phenomena are governed by principles (cohesive beliefs) versus students who believed that science is a…
