In a project to help all professional members of a junior high school staff improve their group processes, a series of training interventions were spaced throughout the school year to increase their organizational abilities. Two days of a six-day summer workshop were spent in structured game-like exercises designed to increase awareness of…

A PREPARATION LABORATORY WAS DESIGNED TO FAMILIARIZE STUDENTS IN ADVANCED MAMMALIAN PHYSIOLOGY WITH LABORATORY SKILLS AND TECHNIQUES AND THUS SHORTEN THE TIME THEY SPEND IN SETTING UP ACTUAL EXPERIMENTS. THE LABORATORY LASTS 30 MINUTES, IS FLEXIBLE AND SIMPLE OF OPERATION, AND DOES NOT REQUIRE A PROFESSOR'S PRESENCE. THE BASIC TRAINING UNIT IS THE…

Project objectives included (1) establishing a body of knowledge concerning the role of the Hawthorne effect in experimental designs in educational research, (2) assessing the influence of the Hawthorne effect on educational experiments conducted under varying conditions of control, (3) identifying the major components comprising the effect, and…

Investments in Prevention is the report of a conference held in May, 1968, at Asilomar, California. The purposes of the conference were to identify and develop a framework for community action and education programs concerned with "young children at risk" and to develop alternative means for implementing comprehensive, prevention-oriented…

Computer time-sharing offers many interesting possibilities for use in teaching computer technology. To test the hypothesis that with proper hardware and software, students using time-sharing as a teaching machine could acquire proficiency in the fundamentals of programing more easily than by using standard batch-processing techniques, the…

In this study, two similar depth perception experiments were conducted to investigate 3-month-old infants' perception of changes in depth while they were being moved. In the first, the subjects, 18 infants (80 to 105 days old) were lowered face down towards the textured floor of a 3-sided enclosure (visual crib). Three experimental conditions were…

Seventeen Portuguese students, between ages 9 and 15, were enrolled in the experimental special class at the Saint-Exupery Co-educational School (Gagny, France) during the 1972-73 academic year. Objectives of the experiment were to: (1) integrate the pupils more speedily into the educational system and, hence, into French society; and (2)…

Reported is a study comparing two laboratory teaching methods used with a college level general physical science course. The criterion instruments used were: (1) Watson-Glaser Critical Thinking Appraisal; (2) The Sequential Test of Educational Progress; (3) Nelson-Denny Reading Test; (4) Welch Science Process Inventory; and (5) The Smith Appraisal…

This newsletter contains student experiments and demonstrations suitable for secondary chemistry instruction as well as laboratory safety tips, book reviews and several activities involving the chemistry of winemaking and crime detection. Articles include those on carbon disulfide bonding, the electrolysis of sodium chloride, a simple and accurate…

Intended to be used along with the "Teacher's Guide to Classroom Discussions for Biology" and the "Teacher's Guide to Laboratory Activities for Biology," this volume presents 43 laboratory exercises for introductory college-level biology. (CP)

This guide is prepared for teachers who have students using the laboratory manual, "Laboratory Activities for Biology." The publication contains some introductory remarks for teachers, lists of materials and equipment, methods of making solutions and other preparations, suggestions for introductory discussions with the class, and…

Albert Michotte, known primarily for his research in perception, also carried out several experiments in logical memory (conceptual or intellectual memory). He was strongly influenced by Kulpe, feeling that the thought processes were autonomous, in contradiction to more traditional and elementary conceptions of mental activity. His experiments,…

The major problem of this study was to assess the effect of computer simulated experiments on the attainment of process skills and the acquisition of subject matter content in the high school physics laboratory. Over a 4-month period, 51 students from 2 physics classes were involved in 4 laboratory experiments and simulations. There was a random…

A fourth quarterly report completes one year of the Educational Policy Research Center's (EPRC) analysis and assessment of the Education Satellite Communication demonstration. Activities and accomplishments during the period April 11, 1975-July 10, 1975 are listed and described. The report also includes cost data from the Appalachian Educational…

This study investigated the feasibility of using computer-simulated experiments in high school physics and chemistry. Fifteen sections of students enrolled in high school physics and chemistry were randomly divided into experimental and control groups. A series of 10 experiments was done by use of computer simulation in the experimental group;…
