This study attempts to determine if varying the amount of content information presented to students has an effect on student achievement. The amount of information was controlled by the notion of concept moves. Also investigated was the effect on student achievement due to different levels of teacher-pupil verbal interaction. Instructional…

The research reported in this document represents efforts to search for the structure and dynamics of the instructional process itself. Without reliable knowledge of these basic facts, improvement of teacher education and the guidance of teachers would remain based on unsystematic experiences and speculation. In order to penetrate the structure…

Weak correlations between indirect teaching behavior, student-directed classroom activities, and achievement in biology are noted. (CP)

Describes a technique for illustrating basic chemical engineering skills in reactor design and process analysis. (SL)

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…

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…

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…

A comparison was made of indirect and direct verbal interaction of science teachers in elementary, junior high, and senior high school levels. Also analyzed were the mean ratios of indirectness compared to teacher experience, knowledge of curricula, and self-perception of teaching method. Data were collected by means of Flanders' Interaction…

This is the second of a two-part review of instructional procedures in secondary school science. Analyzed are research studies in the field mainly over the period 1960-67. Studies were reviewed under the following headings: team teaching, programed instruction, audiovisual aids, laboratory procedures, extra classroom activities and field…

Research indicates that boys perform better on mathematics tests while girls perform better on reading tests. An investigation of why boys' and girls' performance differs was made by coding teacher interactions with second grade students during reading and mathematics instruction. Results reveal that teachers: made relatively more academic contact…

A study examined the impact of teaching handicapped students in regular vocational education classrooms on class interaction and instructional variables. During the study, researchers conducted individual interviews with 22 vocational education instructors from 11 randomly selected school districts throughout Texas and later conducted a total of…
