The primary purpose of this study was to compare regular classroom instruction which used Guided Mental Imagery (GMI) to a non-GMI teaching method. This comparison was expected to yield data which would provide insights relating to the potential of GMI as a useful and effective instructional strategy. Quasi-experimental research methods were followed. The experimental design was a modified "post-test only control group design." Two-hundred-four students in naturally occurring in tact classes formed the experimental and control groups. All groups received instruction in identical science/health content. Two parallel post-tests were administered to all students. Post-test "A" was given immediately after instruction to measure learning acquisition. Post-test "B" was given four weeks later to measure retention of learning. Means for test scores were grouped according to treatment and sub-grouped by the variables: IQ, handedness, identified learning disability, and intellectual giftedness. T_ tests for differences between independent means were conducted. Students' acquisition of basic academic content, when instructed with GMI methodology, was found to differ significantly from students' acquisition of the same content with non-GMI instruction. No statistically significant differences based on instructional methodology were found for content retention. The investigator concluded that GMI instruction may increase learning. Although measures of retention did …

The purpose of this study was to describe factors affecting the use of instructional ideas by secondary teachers in the academic year following a series of staff development sessions designed to present information on effective teaching practices. The research questions addressed the characteristics of information selected for use in classroom practice and the characteristics and relative degree of influence of salient factors affecting the use of ideas. Ten teachers from a large suburban school district in North Texas were selected for this study. Qualitative techniques were used to collect data. Each teacher was interviewed three times and observed in the classroom setting. Documents such as lesson plans were analyzed as a third source of data. Several factors evolved from the data. In varying degrees, these factors predicted teacher use of new instructional practices. Some factors dealt with the teacher's level of understanding and internalization of the information. These factors were labeled as instrumentality, congruence, and analytical thinking. Two other factors which were fairly strong predictors were labeled cost and intrinsic motivation. Cost concerned the amount of time or effort required to implement new ideas versus the perceived benefit to either teacher or student. Intrinsic motivation concerned the personal desire a …
