In an attempt to prevent drug abuse, the U.S. Army developed drug education programs (DEP) at all its installations to inform soldiers about the dynamics and consequences of drug use. This paper presents the findings of the recently completed evaluation of Army DEP. The study surveyed 1,716 enlisted men at 16 posts about exposure to the DEP and…

This paper describes open-ended experimentation with the fungus Pilobolus for laboratory work by high school students. The fungus structure and reproduction is described and sources of the fungus are suggested. Four areas for investigation are suggested: the effect of a diffuse light source, the effect of a point light source, the effect of light…

This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It is intended for college students who are not preparing to become professional physicists. The monograph contains three chapters. Chapter 1 deals with the law of inertia for objects at rest and in…

This book on the growth of word meaning in children focuses on the development of the appreciation of the relations that exist among twenty selected words as the individual matures from childhood through adolescence to adulthood. The four preconceptions which determined the experimental tasks, the set of words used, and the methods of analysis…

Brief, motivating television programs, lectures, calculation exercises, and laboratory experiments were integrated to teach a course in applied electronics at the Royal Institute of Technology (Stockholm). The greater part of the learning work was done in the form of independent study checked by diagnostic tests. These tests proved to have an…

The purpose of this study is twofold: (1) to separate variables combined in the forms of Information Feedback (IF); and (2) to identify additional variables in the effect upon retention of 24 hour delay of feedback. In two of the experiments, the effect of IF delay, immediate test conditions, and different forms of IF upon seven day retention,…

Two procedures were investigated in an attempt to decrease the variability of overlearning response latencies in a study-test paradigm, paired-associate task matching CVC's with response keys: (1) self-pacing the task by presenting test trial stimuli whenever the subject pressed a "home" key; and (2) instructing and shaping subjects to keep home…

The purpose of this study was to describe the level of language maturity and the effect of a preschool language program on the language development of urban, Southern 4-year-olds. The 147 subjects (57 lower status blacks, 40 lower status whites, and 50 upper status whites) all participated in five-day per week prekindergarten programs. Dependent…

This manual describes the scoring procedures for the Greenberger-Entwisle Need-Achievement Pictures. This instrument was developed (1) to provide a set of pictures suitable for a wide age range of subjects, (2) to increase the comparability of findings, and (3) to increase the reliability of measurement. General instructions for scoring the…

This paper comments on Gagne's classification scheme with respect to learning outcomes, and offers a research design appropriate for instructional research studies. It challenges certain assumptions concerning correspondence between subject matter and categories, and asserts that the logic of experimental analysis should be applied to…

The document comprises collections of experimental instructional projects generated by teachers at the Big Ten universities. The projects are usually aimed at improving the conditions for learning in a particular disciplinary area, but many of these arrangements can be easily adapted for use in other departments. The entries in Section 1;…

An information diffusion system was designed and tested that would facilitate the diffusion of innovations on a national scale among community mental health centers. The experimental design used both written and interpersonal techniques. Combinations of the techniques were applied to three treatment groups and a control group. In addition, a…

A computer program to perform a Monte Carlo simulation of counting experiments was written. The program was based on a mathematical derivation which started with counts in a time interval. The time interval was subdivided to form a binomial distribution with no two counts in the same subinterval. Then the number of subintervals was extended to…

The goals of this project were to create a learning environment where the individual talents of each student and staff member could be optimally utilized. Seven specific objectives were a) more flexible space utilization, b) an increase in staff experimentation with different teaching techniques, c) increased process orientation of instructional…

This study analyzed wrist, elbow, and hip actions of golfers who were accurately driving a golf ball a maximum distance. Electrogoniometry and cinematography were used to measure wrist, forearm, elbow, and hip actions during the downswing of 10 low-handicap golfers who were attempting to drive a minimum of 225 yards within a 50-yard corridor.…
