The primary problem was to investigate the relationships between two methods of presenting biological information (lecture-laboratory and audio-tutorial) and students' attitudes toward biology and their terminal achievement. A total of 259 students from Grand Rapids Junior College, Grand Rapids, Michigan, participated while 136 students from…

The intent of this study was to assess the content structure of college biology lectures and to determine the extent to which that structure differed in lectures by a given professor and among lectures of different professors. Content structure was based on the amount of contiguity and commonality of verbal elements between pairs of discourse…

Two teaching methods (learner-centered vs. conventional) were investigated as related to achievement and content covered in a basic electricity course in which 65 students were enrolled. All students participating in the study were given the Bell Laboratories Electricity Examination as a pretest and as a final test. The Otis Test of Mental Ability…

Five randomly selected experimental groups of twenty-four general college chemistry students participated in this study. Four of the five groups received a version of the systems approach treatment, which consisted of group orientation, individualized learning, small group seminars and unit tests. The fifth group was administered the traditional…

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 proposed to determine the occurrence, stability, and character of kinetic structure patterns within college physics lessons. Six lectures were randomly chosen from the schedules of each of six cooperating physics professors and a transcription of audio-tape recordings of each lecture was prepared. The flow of discourse was broken…

The primary purpose of this study was to determine if self-instructional data analysis sessions could be used effectively as traditional college laboratories to reinforce students' understanding of certain principles of mechanics. The secondary purpose was to determine whether any of the 140 college physics students involved had a dependence on…

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…

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…

This investigation studied that relationship between structured teacher-student verbal interaction and critical thinking ability of students in an introductory course in general college biology. This interaction took the form of lecture, of discussion using broad questions, and of discussion using narrow questions as the three primary teaching…

The major purpose of this study was to compare the achievement of junior college biology students taught by two different methods (programed vs. lecture). It was also noted how the two methods of instruction compared in terms of ACT levels with regard to biological achievement scores and, to compare the methods in terms of reading levels, critical…

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…

A special purpose digital computer which utilizes the Monte Carlo integration method of obtaining simulations of chemical processes was developed and constructed. The computer, designated as the Monte Carlo Integration Computer (MCIC), was designed as an instructional model for the illustration of kinetic and equilibrium processes, and was…

All students enrolling in the day sections of Physical Science 101 at Pensacola Junior College (Florida) during the spring semester of 1974 were allowed to register for either audio-tutorial (A-T) or conventional coursework. The A-T group consisted of 144 students in two sections, and the lecture-discussion group consisted of 76 students in two…

This study investigated the development of effective large-group instructional materials which are relevant and meaningful to the general studies biology student. The criterion of student interest guided the selection of birth, birth control, and genetic counseling as topics for developing relevant prototype instructional materials. These…
