Background information, procedures used, and typical results obtained are provided for experiments in which caterpillars are used to investigate energy-flow relationships. Areas in which the experiments could be used include ecology, applied biology, and animal feeding. (DH)

Secondary physics students were interviewed to determine their expectations/actions in laboratory work. Results indicate preference for laboratory activities because such exercises help students remember, are less confusing, and more concrete. Use of the laboratory as an introduction to a concept, followed by discussion, was a key component to…

Describes a general purpose microcomputer-based system designed to support small-scale experimentation in the physical sciences in student laboratories. System requirements, teacher reactions, and educational implications are discussed; design criteria are established; and examples are given of the system's application to some simple experiments.…

Discusses the use of microcomputers in science education: (1) computer-assisted instruction; (2) testing; (3) data processing; (4) simulation; (5) teacher assistance; and (6) data collection. Gives educational applications of microcomputer-based laboratories, pointing out advantages and disadvantages. Outlines current drawbacks and makes…

Presents the historical, technological, and pedagogical factors that led to high expectations in the use of language laboratories for teaching foreign languages. Presents findings of five studies on laboratory effectiveness showing that efficiency tests were largely irrelevant and inconclusive. Includes 10 proposals for language laboratory use.…

Described is an inexpensive wave tank used to study the amplitude of tsunamis travelling down a channel of decreasing depth. A detailed discussion to theory and computations is included. (SL)

Discusses the planning, preparing, assessing, and evaluation of language laboratory technology and pedagogy. (AM)

An investigation was carried out in Sweden to examine language laboratory use. The degree of use, equipment function, method of use, access to lab programs, instruction to teachers on use, teachers' and pupils' attitudes and difficulties were studied by means of questionnaires. Improvement suggestions are made. (CHK)

This resource book contains 40 chemistry labs and provides a single solution to the problems of purchase, storage, use, and disposal of chemicals. The text is designed to be used alone or integrated with current textbooks. A mixture of microchemistry and macrochemistry is used to provide variety and reflects trends in research and industry. Most…

Discusses a lab experiment where rubber bands are used to determine a spring constant and to predict the range when the band is stretched and fired. Included are the formulas involved. (CC)

A study is reported of 715 second year shorthand high school students comparing traditional instruction with laboratory instruction. Students in the shorthand laboratory (individualized instruction through use of various audio taped materials) achieved significantly higher in a transcription task than traditionally-taught students. (SC)

Describes an experiment in environmental chemistry which serves to determine the dissolved oxygen concentration in both fresh and saline water. Applications of the method at the undergraduate and secondary school levels are recommended. (CC)

Discusses the use of aluminum chloride and other Friedel-Crafts type catalysts to polymerize 2-methylpropene and the application of such products in industry and agriculture. Includes a laboratory experiment on the polybutene preparation suitable for high school purposes. (CC)

Describes a number of activities and experiments designed to add interest and increase understanding in the secondary school physics laboratory. (JR)
