Describes a Grignard reaction in a step synthesis that can be used in the laboratory to demonstrate several experimental and instrumental techniques. (MLH)

Describes an experiment that follows the progress of a chemical reaction with radiochemical tracer techniques, using the beta-emitting radioisotope iodine 131. (MLH)

Describes a student computer experiment that shows how the properties of the star, the temperature, and the opacity determine the nature of the observed spectrum of a star. (MLH)

Describes the construction of an amplifier and force transducer that can be used to demonstrate electrical activity in nerve and muscle using the gastrocnemius muscle and sciatic nerve of the frog. (MLH)

Subjects read a supposedly real news account of a medical experiment in which the scarcity of the treatment employed and the amount of scientific justification for the experiment were experimentally varied. Factors that might influence public attitudes about social experiments are explored. (Author/DEP)

Discusses the question of appropriate research methodologies for social psychology research, casting "involved participation" and role enactment as contrasting methodologies, with deception used in either case where necessary. Involved participation is considered to be more flexible and more suited for the testing of hypotheses whereas role…

Attempts to relate psychosocial maturity to social behavior, specifically, to interpersonal attraction. (Author/RK)

Tests two theoretical accounts of imagery on paired-associate learning. These two theories, differentiation theory and mediation theory, have been proposed to account for the finding that stimilus imagery/concreteness is an important variable in paired-associate learning. (Author/RK)

In 1974 Wood proposed a hybrid serial-parallel model to account for the within-stimulus interactions between the acoustic cue of "pitch" and the phonetic cue of "place". These experiments found Wood's research independent of his subjects' experience, the order of cue presentation, and whether the cues are presented simultaneously or sequentially.…

Considers listener expectancies based on timing redundancy in continuous speech and the interaction between the effects of segmental and suprasegmental cues during ongoing perception. (Editor/RK)

Presents the results of a survey of English physics teachers concerning the percent of classroom time they spend in practical work, the objectives of practical work, and their use of student projects. (MLH)

Discusses the philosophy and organization of an introductory college physics course that emphasizes laboratory experiments. Also presents a brief outline of the laboratory work. (MLH)

Describes an introductory laboratory physics course covering dynamics, fields, and waves. The course involves six hourrs of laboratory work and six hours of self-study every two weeks. Understanding concepts rather than laboratory techniques is stressed. (MLH)

Describes a laboratory teaching technique in which a single topic (in this case, bipolar junction transistors) is studied over a period of weeks under the supervision of one staff member, who also designs the laboratory work. (MLH)
