This document begins with a report of a study of the learning styles of American Indian students at the Sante Fe Indian School (New Mexico). Santa Fe Indian School is a secondary school of 550 students, primarily from the Pueblo communities of New Mexico. A learning style assessment instrument was administered to 459 students, Grades 7-12, in 4 tribal language groups. A preferred instructional style was not found overall or for any of the tribal language groups. Analysis of student profiles suggests that teaching strategies and curriculum should focus on: small-group learning activities; developing a positive rapport between teachers and students; augmenting information-processing skills that address right and left hemispheric approaches to learning; and developing a flexible instructional delivery that incorporates information on individual learning styles. Following the report, 14 social studies and language arts lesson units, developed for Indian middle school students as a result of the study are presented, based on the 4MAT instructional model that acknowledges a diversity of learning styles and incorporates both right and left hemispheric modes of learning. The units cover various topics related to American Indian history and culture, cultural exchange, outdoor education, study skills, and thinking skills. Each unit consists of lesson plans and learning activities related to creating and analyzing an experience; integrating experience with analysis; teaching, practicing, and personalizing the concept; analyzing personal application; and celebrating knowledge gained.
