Level II, General Public Access, of a 5-stage madel of public access to computers through science-technology centers is described. Tables contain categories and examples of interactive computer games and programs, and computer classes offered at various science centers. (CMV)

The conclusion of a six-part series on planning and designing media facilities deals with problems of security. (Author/MLF)

A model of Brownian motion is discussed which includes viscosity effects. The model lends itself to Monte Carlo simulation and thus is suitable for an elementary physics laboratory experiment. (BB)

Described is a mouse cage that can be built, at a cost of about $15, by intermediate-aged elementary students. (BB)

This article discusses how the industrial arts teacher can help foster growth and independence by anticipating and being sensitive to the needs of visually handicapped students in the following areas: equipment operation, orientation, and mobility in the shop; material aids; and devices for adaptation. (BM)

Describes science-related competitive events in which 10th and 11th grade students participated. The organization and operation of the olympiad is detailed. (CP)

Describes a final year undergraduate course in which students use X-ray diffraction to identify clay minerals. (SL)

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…

Presents an experiment in which students prepare salt-water taffy, and concrete props for teaching weak acids and bases. (SL)

Statistical laboratory exercises designed to promote better understanding of statistical concepts in an introductory non-calculus statistics course are illustrated. The exercises make extensive use of data that are individually generated by tables of random digits or by computer. (MN)

Discusses building memory ability, Agatha Christie's and Sherlock Holmes' chemical abilities, and excerpts from now unpublished laboratory manuals. (SL)

If academically disadvantaged adults are to succeed in learning, they must be proficient in reading, writing, listening, and speaking. Presents the major conceptual considerations implemented at the University of Akron (Ohio) in conducting laboratories which provide academically disadvantaged adults an opportunity to practice these skills. (EM)

Two areas in which language laboratory programs can be improved--training teachers in nonverbal aspects of communication and maintenance of an adequate supply of taped materials--are discussed. (RM)

Describes a series of activities which will demonstrate electrostatic phenomena. (CP)

Compares this instructional approach with the traditional-classroom method and suggests equipment that an English workshop needs. (RL)
