This action research project implemented and evaluated a program to improve student motivation through the use of cooperative learning and multiple intelligences. The targeted population consisted of students in fourth, sixth, and tenth grade in a consolidated school district located in a rural area in the Midwest. The problems of low academic achievement and inappropriate behavior were documented by means of school records, structured observations, and student questionnaires. The seven-month intervention consisted of a cooperative learning curriculum and the adoption of a multiple intelligences approach, emphasizing the development of appropriate social skills and conflict management. Data on student progress were obtained on a pre-post basis by means of student surveys, teacher observation checklists, and teacher-made tests. The post-intervention data indicated that engaging students in cooperative learning, implementing multiple intelligences, and providing a variety of student activities improved academic achievement and resulted in a decrease of inappropriate behavior.
