The objective of this research was to contrast the effects of two instructional techniques (programmed vs. conventional) used in beginning college biology courses. The experimental technique involved the use of programmed textbook units within the typical course syllabus. Ninety students were involved in the study. Four programmed texts were used.…

This was a quantified study on the learning of certain theoretical topics in general chemistry as influenced by two methods of visual technique (single concept films, overhead projections). Four classes of chemistry students (non-science majors) registered in sections on a random basis, participated. Objective, multiple choice tests on each of the…

The problem of this investigation was to compare the effectiveness of the lecture-discussion method of instruction and the multimedia programmed method in promoting achievement in a noncredit, college level physics course. The three instructors taught 180 freshmen who had failed to achieve a minimum grade of 70 percent on a physics placement…

This study was designed and conducted to determine the effectiveness of audio-tutorial minicourses in increasing achievement in the biological sciences at the college freshman level. In 1971, 75 randomly selected students in the experimental group attended regular lecture and laboratory periods in addition to completing 10 minicourses. The 79…

The major purposes of this study were to evaluate the effect of the use of slide/tape units as an instructional aid for the teaching of laboratory technique in the college general chemistry laboratory and to determine if special instruction in creativity would effect creativity in chemistry. The units were evaluated under three conditions of…

In an attempt to compare two methods of instruction in environmental education, an instructional unit based on the balance of nature concept was developed according to a table of specifications which followed Bloom's Taxonomy of Educational Objectives: Cognitive Domain. Two versions of the instructional unit were prepared, one utilized a field or…

The purpose of this study was to develop and evaluate an instructional model which utilized the computer to produce individually prescribed instructional guides in physics at the secondary school level. The sample consisted of three classes. Of these, two were randomly selected to serve as the treatment groups, e.g., individualized instruction and…

The basic problem examined was whether it is essential that secondary students be required to attend daily classes while studying beginning biology using the SYSTEMS APPROACH TO BIOLOGY program as a method of instruction. The study did not identify the population used nor how it was selected. Students were administered a pretest and posttest,…

This study was designed to develop, revise, and evaluate modules for individualized self-instruction in areas pertinent to the teaching performance of graduate assistants in microbiology. Six modules presenting competencies and skills of teaching were designed and developed. Eighteen teaching assistants were randomly assigned to one of two…

This study was designed to evaluate the effectiveness of a self-developed audio-tutorial (A-T) system in biology at the college level. The basic design of the study was a variation of a compromise experimental group-control group design. The control group was instructed by lecture-laboratory method, and the experimental by the A-T system. Facutal…

Because of a reading difficulty resulting in inability to acquire new information and concepts from the textbook used in a technical Physics I course, the investigator felt it appropriate to find another way for presenting the material. Since these students were majoring in electronics technology, they require good technique in the laboratory. The…

This study was designed to determine if an adapted version of Physical Science for Nonscience Students (PSNS), a physical science course used for nonscience majors in college, significantly contributes to an understanding of the scientific enterprise, positive attitudes toward science and scientists, and knowledge of solid matter and the…

The purpose of this study was to determine to what extent the breakdown of Newtonian classical physics and the new concepts of modern physics have changed the treatment of elementary physics in undergraduate college textbooks and to evaluate implications of the change. Forty-three textbooks published between 1910 and 1966 were examined and placed…

Two instructional methods were identified and compared to determine if any significant differences could be noted on three criterion measures. Measurements were conducted in the areas of achievement in biology, science attitudes, and critical thinking ability. Student ability was measured using pre-tests and the Scholastic Aptitude Test. Students…

An attempt was made to compare two instructional techniques. The study involved 64 students in two experimental groups and 65 as controls. Two instructional treatments (scripts and tapes) and two units of biological subject matter were utilized. One experimental group was given audio tapes, the other written scripts for the first unit. In the…
