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…

This investigation compared time-compressed lectures with lectures taped at a normal word rate and examined the direct application of compressed lectures to the educational process. Participants in this study, 87 college students enrolled in Botany 100, were randomly assigned to four groups--one control group and three treatment groups. The…

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 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 purpose of this study was to determine if any significant differences existed in the achievement scores of students who complete a business report writing course in an individualized instruction method as compared with those students who complete the same course in a traditional teacher-lecture method. Five hypotheses were analyzed for…

This doctoral thesis analyzes the effect of mastery and nonmastery teaching procedures upon student achievement and attitudes in an introductory college-geography course. Mastery learning is the teaching strategy where each segment of materials must be mastered before instruction can begin on the next segment. A classroom lecture-discussion method…
