The purposes of this study were: to determine the degree to which student attitudes were changed by the use of minicourses and to produce a model which could be used by other academic departments interested in the use of minicourses. The study included 240 students in four sections of Earth Science at the University of Northern Colorado. Each…

Three course patterns are currently available to laboratory technician trainees in Kenya. Students may select the full time option (attending classes full time), the sandwich option (alternating between a term of employment and a term of full time studies), or the day release option (attending classes one full day per week from 8:00 a.m. to 6:30…

The purpose of this study was to design a course and to determine its effects on learners' perceptions of certain scientific literacy concepts. A science-related semantic differential instrument was used. Student-instructor collaboration resulted in the selection of objectives and learning strategies in order to establish an environment favorable…

The problem of this study was to compare teaching methodology and teaching strategies used in general chemistry courses to the attitudes and values of the students taking those courses. Objectives of the study included: (1) an investigation of the teaching methodology in use in chemistry courses, (2) a study of the attitudes of students toward…

The purposes of this study were to investigate science teachers' attitudinal changes toward an innovative science curriculum and to ascertain what variables were pertinent to these changes. The population consisted of 55 college science teachers assigned to participate in the program beginning with the summer of 1971. The instruments used were:…

The major purpose of this study was to design and evaluate a programed instructional unit for a first year college chemistry course. The topic of the unit was the categorization and solution of acid-base equilibria problems. The experimental programed instruction text was used by 41 students and the fifth edition of Schaum's Theory and Problems of…

Reported is a study to determine if significant differences existed between samples of students with regard to certain scholastic and demographic variables, to collect information as to why students chose a particular track and remained with it, and to determine students' reaction toward the track followed. The population consisted of college…

This study concentrated on three problems dealing with academic backgrounds related to achievement in college freshman programs in chemistry. One problem was related to the high school science curriculum. The other problems involved the possibility of devising a prediction scheme based on a student's academic background, and the possibility of…

The purpose of the study was to establish a list of acceptable terminal behavioral objectives for the nonmajor general biology laboratory as perceived by each instructor in every institution for higher education in the state of Missouri who is responsible for planning, organizing, operating, and evaluating that course. It was further the purpose…

This study compared the effectiveness of three sequences of prerequisite courses required before taking zoology. Sequence 1 prerequisite courses consisted of general biology and human biology; Sequence 2 consisted of general biology; and Sequence 3 required cell biology. Zoology students in the spring of 1972 were pretest and a posttest. The mean…

This study traces the development and testing of a particular modular curriculum design that was set up where curriculum planners produced one single-level course offering for both college biology majors and non-majors. In this design, major units of study are broken into units. In each there is a basic module completed by all students in which a…

In order to study the mechanism of student interest in a physical science course when the majority of students were interested in fields other than science, a system of measuring instruments was applied for detection of significant differences between two teaching methods used for this course. The study utilized the measured responses of 105…

The goal of this research study was to develop laboratory materials which would present concepts about plants and selected processes of science to undergraduate elementary education students. Three laboratory exercises, each covering a number of concepts dealing with an identified topic, were used. Behavioral objectives were used to combine major…

Compared were attitudinal characteristics and achievement in a college chemistry course offered by two different instructional methods. The experimental group received closed-circuit television instruction, and the control group was instructed by lecture and recitation. All students were pretested with the American Chemical Society-National…

This study was designed to assess the effects of the problem-oriented method compared to those of the traditional approach in general chemistry at the college level. The problem-oriented course included topics such as air and water pollution, drug addiction and analysis, tetraethyl-lead additives, insecticides in the environment, and recycling of…
