Investigated were whether differences exist in the verbal behavior of effective and less effective secondary school biology teachers. From a population of 29 biology teachers a sample of five effective and five less effective biology teachers was selected. Effectiveness was determined by a teacher's combined score on the Teacher Rating Scale,…

A category system consisting of 36 categories was developed for classifying the verbal behavior of each pupil in high school biology lecture-discussion classes. Two classes each of eight high school biology teachers were observed and tape recorded for four consecutive days. Classroom interaction was coded combining a teacher-behavior category…

Developed was a category system for systematic observation of the verbal and non-verbal behavior of high school biology teachers in both classroom and laboratory situations. This system was used to study the similarities and differences existing between the Biological Sciences Curriculum Study (BSCS) and non-BSCS teachers. Individual teachers…

Reports degree of relationship between assessments of teachers' procedural and verbal behavior made independently by teacher self report, student checklists, and the observations of an outside observer. (AL)

THIS STUDY WAS CONDUCTED TO DETERMINE THE RELATIONSHIP BETWEEN THE VERBAL BEHAVIOR OF STUDENT TEACHERS AND THE ACHIEVEMENT AND SELECTED ATTITUDES OF EIGHTH GRADE STUDENTS. TEN STUDENT TEACHERS PARTICIPATED IN A WORKSHOP DESIGNED TO PREPARE THE STUDENT TEACHERS TO TEACH SCIENTIFIC INQUIRY. THE STUDENT TEACHERS WERE RESPONSIBLE FOR TEACHING A…

Developed was a category system for first-hand systematic observation of the verbal and non-verbal behavior of high school biology teachers in both classroom and laboratory situations. This was used to investigate correlations between selected personality traits and the verbal and non-verbal behaviors of high school biology teachers. Some…

Predictions from Anderson's theories of structured communication were tested in grade eitht biology classes. Students given verbal instruction with a high degree of structure performed better on acquisition tests than students receiving less structured lessons. (AL)

Investigated was the kind of communication that takes place in oral teaching. Analysis of tape-recorded transcripts of fifteen half-hour biology lessons delivered to high school and college students revealed a high degree of teacher-dominance and infrequency of discussion involving several pupils.
