This manual provides numerous experiments for college-level microbiology students illustrating the basic principles in phage, tissue culture, and animal virology. (CS)

EIGHTEEN DEMONSTRATIONS ON THE SUBJECT OF SOIL AND WATER CONSERVATION ARE PRESENTED. THESE DEMONSTRATIONS UTILIZE SIMPLE AND INEXPENSIVE EQUIPMENT AND ARE SUITABLE FOR CLASSROOM OR OTHER GROUP USE, ALTHOUGH THEY WERE DESIGNED FOR 4-H CLUBS. LISTED ARE THE EQUIPMENT AND MATERIALS NEEDED, PREVIOUS PREPARATION, STEPS IN THE DEMONSTRATION, AND…

An experiment was designed to investigate the effects of classroom observation on the attitudes of education majors toward selected aspects of teaching. Three major hypotheses were considered: (1) that observation of classes would result in a significant change in student attitudes toward selected aspects of teaching, (2) that student attitudes…

This document discusses the plans and the implementation of plans for the National Conference on Curricular and Instructional Innovation for Large Colleges and Universities, held at Michigan State University, November 6-11, 1966. The purposes of the conference were (1) to identify through discussion and demonstration promising curricular and…

A required senior-level chemical engineering course at Colorado State University is described. The first nine weeks are devoted to the theory portion of the course, which includes the following topics: LaPlace transformations and time constants, block diagrams, inverse transformations, linearization, frequency response analysis, graphical…

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…
