The first volume of a program to increase the academic growth of preschool and primary grade children through the utilization of brain hemisphere research, this manual outlines brain dominance theory and provides two instruments for assessing students' preferred style of learning. Material is provided in eight sections. Section 1 introduces the teacher to right and left brain research and teaching strategies. Section 2 contains guidelines for administering and evaluating the two tests of brain hemisphere ability. The importance of individualizing learning activities based on test findings is addressed in section 3. An overview of lesson plans and specific teaching strategies are provided in sections 4 and 5. Section 6 outlines the application of this program at one preschool. The bulk of the manual (section 7) contains the materials for the tests of left hemisphere and right hemisphere ability. The test of left hemisphere ability contains 25 items which the student listens to and tries to repeat accurately. Included in the right hemisphere test are 19 items which require the student to identify objects by naming partially completed pictures. A final section consists of a set of activities designed to improve and integrate right and left brain processes. A bibliography is included. (LP)
