This bulletin describes a procedure to provide graduate students with meaningful lab experiences, and to integrate the study of a variety of group counseling approaches with actual group leadership opportunities. It allows the beginning group counselor to develop confidence before working with emotionally disturbed clients, and also provides…

This document presents a series of physics experiments which allow students to determine the value of unknown electrical capacitors. The exercises include both parallel and series connected capacitors. (SL)

Describes a computer program which permits students to check their calculations while they are still in the laboratory by entering their raw data and calculated results via a teletype terminal situated in the lab. The input is examined and the student is informed of the nature of each error. (MLH)

Describes an arrangement of a laboratory course in biochemistry designed to teach currently used biochemical techniques and then have students apply the procedures in a real research program so as to give students a better understanding of biochemistry. (BR)

Contains a checklist of 36 non-operationally stated items and an evaluation of each by a faculty group of 30. Reports the need for non-cookbook experience, an emphasis on knowledge of specific instruments, and the essential function of laboratory as a teacher of the theory and process of experimentation. (GH)

The Laboratory Structure and Task Analysis Inventory (LAI) is an instrument designed to facilitate the analysis of laboratory investigations in secondary school science. It yields a quantitative picture of the kinds of activities required of a student in performing laboratory investigations. The report includes guidelines for the use of the…

The experiments in this manual represent state-of-the-art techniques which should be within the budgetary constraints of a college physics or chemistry department. There are fourteen experiments divided into five modules. The modules are on X-ray fluorescence, charged particle detection, neutron activation analysis, X-ray attenuation, and…

This study was designed to investigate and analyze specific instructor and student behaviors in introductory and advanced laboratories of five science disciplines (botany, chemistry, geology, physics, and zoology) at a major midwestern university. The instructor sample involved teaching assistants from various science departments. The student…
