The results of an experimental project in American history which introduced to students the methods of historical investigation in specific historical areas through small group research rather than through the college survey course are described in this report. Discussed are (1) the course organization, consisting of two semester units in which…

Language laboratory effectiveness in secondary schools and related research are discussed. Criteria for five elements determining the laboratory's effectiveness are described: (1) the teacher, (2) the teaching materials, (3) the testing and grading programs, (4) the student practice sessions, and (5) the equipment. Some general remarks are made…

An attempt at promoting greater variety and thus better student attitudes toward open languages laboratory attendance involves a set pattern of five specific steps in the preparation of taped exercises. Three basic principles are prescribed and illustrated by examples in German, French, and English as a foreign language. (RL)

This report summarizes the major features of a 1973 summer conference (at the New York State University at Buffalo) on listening as an essential feature of communication and problems relating to students' listening skills. The conference was held because of an awareness that little attention is being paid to listening comprehension in the…

Discusses undetected hazards that may have potential for injuring staff and students. Cites examples of chemical hazards in the lab. Stresses the need for laboratory safety education. Gives examples of safety publications for secondary and college science laboratories. Comments on the changing nature of chemical safety standards. (CW)

Describes exercises used for the first two weeks of general chemistry when class rolls are fluctuating. Includes learning objectives, linear graphs, nonlinear graphs, scatter graphs, and precision of measurement. Exercises are designed to introduce students to the metric system, balances, significant digits, graphing, and computerized data…

Discusses the concern for safety in chemistry courses. Includes a medical information form on which students can provide information that may be important if an emergency should occur. (TW)

Describes the use of analysis of rotational faults in undergraduate structural geology laboratories to provide students with applications of both orthographic and stereographic techniques. A demonstration problem is described, and an orthographic/stereographic solution and a reproducible black model demonstration pattern are provided. (TW)

Discusses a new program at the University of Michigan in hazardous waste management. Describes a laboratory demonstration that deals with the reactivity and potential violence of several reactions that may be encountered on a hazardous waste site. Provides criteria for selecting particular compatibility testing methods. (TW)

Discusses the use of a computer software package called ASYST for general laboratory computing. Describes the software's capacity for acquiring data in a flow injection analysis experiment. Reviews the series of commands used by students in carrying out the experiment. (TW)

Discusses the problems created by the insufficient number of major data collection and analysis instruments in most college chemistry courses. Suggests the use of less expensive microcomputer-controlled instrument emulators, which resemble the actual instruments. Discusses the application of one such emulator in an instrumental analysis course.…

Describes an experiment that demonstrates the use of HPLC in simultaneous multi-element analysis. Discusses the application of this process in identification of steels and trade effluents. (TW)

Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)

This resource manual focuses on physics labs that relate to the world around us and utilize simple equipment and situations. Forty-five laboratories are included that relate to thermodynamics, electricity, magnetism, dynamics, optics, wave transmission, centripetal force, and atomic physics. Each lab has three sections. The first section…

Wright State University School of Medicine uses community pathologists as unpaid volunteers to team teach pathology courses, making possible a small-group approach in the laboratory. The organization of the course and faculty teams, student evaluation, and results of this approach are discussed. (JMD)
