This guidebook is based on research on the human brain and the way it processes information. It is noted that current research on the learning process has investigated the differing functions of the left and right brain hemispheres. This research supports the theory that students are inclined to learn through different modalities (tactual/kinesthetic, visual, or auditory) and that teaching styles and classroom environment can be modified to meet the needs of different kinds of learners. The guide provides information on indicators and predictors of learning styles and effective teaching strategies for students with particular learning styles. An overview is presented of learning style inventories and trial lessons which have been developed to determine a student's learning style. A learning style inventory is included, offering a comprehensive approach to diagnosis of an individual's learning style, and an informal checklist for student use provides clues to characteristics which may influence learning style. Classroom activities for students from grades 7-12 are presented, each geared to be effective with combinations of kinesthetic, tactual, visual, and aural learning styles. (JD)
