The National Association of Secondary School Principals (NASSP) published a new learning style instrument in 1986--the NASSP Learning Style Profile (LSP). The LSP yields independent scores on 24 discrete elements of learning style. Its purpose is to provide educators with a well-validated and easy to use instrument for diagnosing cognitive styles, perceptual response tendencies, and study and instructional preferences of middle level and senior high school students. The LSP offers school practitioners a way to personalize the instructional process, identify the dominant stylistic characteristics of students, and plan instruction accordingly. This practical guide presents exercises to enhance the cognitive skills diagnosed by the LSP. The exercises, which draw on sample items from the LSP, are designed to augment each of the following areas: (1) analytic skill; (2) spatial skill; (3) discrimination skill; (4) categorization skill; (5) sequential processing skill; (5) simultaneous processing skill; (6) memory skill; and (7) verbal-spatial preference. Grade-level designations are listed for each activity. Appendix A provides a key to complicated performance activities, and Appendix B presents a LSP interpretation form. (SLD)
