After extinction of fear to a Pavlovian conditional stimulus (CS), contextual stimuli come to regulate the expression of fear to that CS. There is growing evidence that the context dependence of memory retrieval after extinction involves the hippocampus. In the present experiment, we examine whether hippocampal involvement in memory retrieval…

Nanoscience refers to the fundamental study of scientific phenomena, which occur at the nanoscale--nanotechnology to the exploitation of novel properties and functions of materials in the sub-100 nm size range. One of the underlying principles of science is development of models of observed phenomena. In biology, the Hardy-Weinberg principle is a…

Defines the self-study group and differentiates it from other laboratory training groups. Investigates the effects of sex and style of the facilitators on group members. Presented at the American Group Psychotherapy Association Convention, Boston, Mass., February, 1976. (HMV)

The Impromptu Teaching Model was designed by the University of Central Arkansas for use by preservice teachers in laboratory teaching experiences. Two teaching exercises, microteaching and reflective teaching, form the basis for impromptu teaching. Microteaching provides teachers with the opportunity to master various technical skills of the…

This is the report of a study of the effects of an optional attendance policy on actual lecture and laboratory attendance and on cognitive examination performance in the medical physiology course at the University of Kansas Medical Center. (Editor)

SEVERAL STUDIES OF LABORATORY TRAINING PROGRAMS IN INDUSTRY ARE ASSESSED IN TERMS OF THEIR POTENTIAL USEFULNESS (DO THEY ACCOMPLISH INTENDED CHANGES IN PARTICIPANTS THAT ARE LASTING OR SELF-REINFORCING, AND HOW DO THEY COMPARE WITH OTHER METHODS IN ACCOMPLISHING SIMILAR GOALS) AND ACTUAL CONTRIBUTION (DOES PARTICIPATION LEAD TO LASTING CHANGE IN…

The problem of this study was to assess the effects of a three-day residential human relations laboratory on flexibility and supervisory attitudes. An instrument constructed by Felker and Smith designed to further 'operationalize' the construct of philosophic-mindedness was used to measure flexibility. Supervisory attitudes were measured by an…

This study investigated the influence of the feedback a teacher expects to receive after teaching on his preference for expository or discovery teaching styles. The subjects were 88 undergraduate educational psychology students at the University of Texas at Austin. Each completed a three-part questionnaire, the Teaching Style Inventory (TSI),…

The purpose of this study was to investigate the relative effects of different modes of supervisory feedback on the development of beginning teacher candidates' refocusing behaviors. Thirty-nine secondary teacher candidates served as subjects. They were enrolled in two sections of the course taught by the same instructor and were assigned randomly…

This paper discusses some of the problems encountered in conducting behaviorally oriented programs, using a small group laboratory approach, in developing nations. The organizational and social contexts in developing nations which might contribute to issues in management training are briefly outlined. Specific problems relating to training…

With the use of classroom simulations, theory and field research can be synthesized, thus bringing both theory and research into an "action" form for the education student. Interactive computer systems allow for active involvement and immediate feedback. One classroom simulation, already constructed, is described. For this simulation a…

This paper describes a cooperative program among the public schools, local Parent Teacher Associations, and the Auburn University Education Department in Montgomery, Alabama. In the program, Auburn University students were enrolled in block courses in the areas of language arts, social studies, mathematics, and science and worked from four to six…

The present volume outlines the reasons, facilities, activities, schemata, and suggestions for setting up a functional social studies laboratory in the hope that the quality in social studies education will be improved. Approximately half of the book offers sources of materials for the benefit of teachers. Labs are not only a repository of…

This publication should be useful for those who are interested in the theory and application of isotopes and radiation in agriculture and entomology. There are two main parts in the publication. Part I, entitled Basic Part, includes topics which an individual should know about radioisotopes and radiation. There are laboratory exercises included in…

Describes a grading technique for a laboratory program, designed to apprise the student each week of his performance and relative standing with peers. (SLH)
