This paper describes an attempt to evaluate the contribution of laboratory experiments on student achievement in an elementary, one-term college chemistry course and suggests some less expensive alternatives. (Author/BB)

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 Laboratory Structure and Task Analysis Inventory (LAI) is an instrument designed to facilitate the analysis of laboratory investigations in secondary school science. It yields a quantitative picture of the kinds of activities required of a student in performing laboratory investigations. The report includes guidelines for the use of the…

The primary purpose of this study was to determine if self-instructional data analysis sessions could be used effectively as traditional college laboratories to reinforce students' understanding of certain principles of mechanics. The secondary purpose was to determine whether any of the 140 college physics students involved had a dependence on…

Establishes the extent to which practical work in South African high schools varies with respect to factors such as gender of student, type of school, medium of instruction, and examination board. Investigates the relationship between experience of experimental work and pupil attainment as measured by matriculation grade. (Author/GA)

Reports on an undergraduate laboratory course designed to provide instruction and practice in the intellectual skills of application, analysis, and synthesis, and in Piaget's formal operations. A 10-item exam used to measure these skills is included as an appendix. (Author/CP)

Discusses the characteristics and development of a computer simulation laboratory for educational administration research at the University of Wisconsin at Madison, and reviews an experimental study performed at the laboratory on stress in decision-making. Explores how simulations provide researchers access to experimental conditions unavailable…

Examines the psychology of learning and its application to work in the laboratory. States that the working memory capacity of students is limited; therefore the amount of information they can process needs to be controlled and "recipe following" in the laboratory is perfectly reasonable. (RT)

This paper is a discussion of how videocassette tape recording is used and the results of its use, in general chemistry pre-laboratory instruction at the University of Southern Mississippi. (Author)

Presents samples of educational material adapted for laboratory use on the subject of the pH scale, dilution skills, and their relevance to biology. The experiments were developed for use in both ninth-grade heterogeneous and tracked classes in biology. Students were assessed for academic achievement in relation to their operational reasoning…
