The Laboratory of Comparative Human Cognition has found that, if cross-cultural psychology has mounted a challenge to developmental psychology, it is because it has forced recognition of the fact that no context of observation, including the laboratory, is culturally neutral. Settings for behavior are embedded in larger systems of social…

Presents the results of the evaluation of a self-paced freshman physics laboratory and its assessment procedures used in the first-year physics course at the University of Adelaide, South Australia. (HM)

Presents details of anodic stripping analysis (ASV) in college chemistry laboratory experiments. Provides block diagrams of the analyzer system, circuitry and power supplies of the automated stripping analyzer, and instructions for implementing microcomputer control of the ASV. (CS)

Describes the process of collecting and maintaining a culture of protozoa. Instructions are also given for constructing a micropipette for transfering small organisms. (SA)

Discusses general strategies and specific devices to motivate intermediate and advanced students to use the language laboratory frequently and efficiently. Suggests types of materials most effective for language laboratory use. (PMJ)

This experiment, in which students experiment on themselves, involves carrying out analytical methods for vitamin C using instrumental and "wet" techniques. (SA)

An 18-month study of an elementary school computer laboratory is discussed. (MK)

Focuses on rewards in scientific research. Discusses the social structure of science and its ability to inhibit creativity as ilustrated in the work, "The Act of Creation: Creative Processes in Science." This is related to accounts of the discovery of the chemical structure of DNA. (SA)

Describes and evaluates a learning center approach to economic education which involved secondary social studies students at the University of Texas, Austin. The subject of the learning center project was how to purchase and maintain an automobile. Findings indicated that the approach was successful and interesting to students. (Author/DB)

Describes an experiment in which an air table is used to measure the moment of inertia of air pucks with various radii and mass loadings. (BT)

Divides the stated aims of practical work, listed in some of the A-level syllabuses of the GCE examining boards, into four groups and discusses each: didactic aims, the development of skills, the scientific method, and affective aims. (GA)

Gives a brief description of open-circuit wind tunnels of rectangular cross-section and of how expanded polystyrene can be used to build a small one. (Author/GA)

Discusses the following: another version of Doppler beats; alternate proof of spin-1 sin-1/2 problems; some mechanisms related to Dirac's strings; Doppler redshift in oblique approach of source and observer; undergraduate experiment on noise thermometry; use of the time evolution operator; resolution of an entropy maximization controversy;…

A novel and efficient (34 percent overall) multi-step synthesis of the housefly sex attractant, muscalure, is described. Each of the steps involves types of reactions with which the undergraduate student would be familiar after one-and-one-half semesters of organic chemistry. (BB)

Description of the Laboratory School, its objectives, and how it provided a testing ground for Dewey's philosophy that history is useful as an analytical tool. Examines Dewey's belief that children gain insight into the principles and complexities of their own society by tracing historical origins and development through the process of…
