Examines hydraulic jumps and suggests several simple experiments which can be carried out with limited equipment. (DS)

Discusses theory of the rotating mirror, its use in measuring the velocity of the electrical signal in wires, and the velocity of light. Concludes with a description of the manometric flame apparatus developed for analyzing sound waves. (SK)

An Osmette A model 5002 automatic osmometer is used to characterize different drugs, diluents, and adulterants commonly encountered in samples of forensic interest, permitting rapid determinations with good reproducibility and use by large numbers of students with little training. Includes background information, procedures, and typical students…

Discusses several coupled pendulum systems suitable for classroom demonstrations or on an overhead projector. (SK)

Presents discussion on: (1) computer assisted synthesis in industry and academia; (2) computer applications to teaching organic synthesis; (3) a computer program (ORGSYN) incorporating reactions to synthesize aliphatic compounds; and (4) the design of a computer program as a heuristic device in an introductory organic course. (SK)

Presents a set of simulation models for use in teaching population dynamics. These models are designed specifically for use with a programmable pocket calculator, and can be used to demonstrate growth of populations with discrete or overlapping generations and also to explore effects of density-dependent and -independent mortality.

This is the 1979 annual report of the American Chemical Society's Committee on Professional Training. Included are data on total numbers of bachelor's, master's, and PhD degrees awarded in 1978-79 whose programs are ACS approved. An increase is reported in the number of bachelor's degrees in chemical engineering. (SA)

Describes an instruction system combining features of lecture and independent study methods, including course management and instructional materials. Compares course to lecture and independent study sections. (SK)

This investigation focused on the stage of formal operational reasoning in the acquisition of astronomy concepts, and on efficacy of different instructional experiences for facilitating cognitive change in college students. Included are selected results and directions for future research. (SK)

Reviews the development of solid-state physics. Topics include phase transitions, materials science, superconductivity, and superfluidity. (JN)

Demonstrates that computer aided energy analysis improves students' (N=29) comprehension and prediction accuracy of energy consumption in buildings and confirms that a reasonably accurate building energy analysis computer program can be designed for student users. (Author/SK)

Discusses field collection, preservation and storage techniques, and identification of slime molds (with fruiting bodies). (DC)

Critiques Slusher's account of creationist cosmology, with occasional reference to other relevent creationist theories. Points out the fallacies and contradictions on seven topics, including the structure of the galaxies, Olber's Paradox, traveling of light in space, and changes in Saturn's rings. (DC)

Cognitive performance of college students (N=225) on "An Inventory of Piaget: Developmental Tasks" (IPDT) was related to Scholastic Aptitude Tests and performance in both college chemistry lectures and laboratory classes. Relationship of Piagetian tasks to learning and instructional activities in introductory chemistry classes is…

Results of on-site inspections of 11 New York colleges, laboratories and storage facilities are summarized according to: (1) chemical storage and disposal; (2) safety equipment; (3) ventilation; (4) general housekeeping; and (5) safety education. (Author/SK)
