This practicum report describes a program in which strategies for improving self-managing behavior skills of second graders were designed and implemented. The goals of the Self-Management and Responsibility Training (SMART) Program were to improve students' behavior and encourage development of students' critical thinking skills. The four basic strategies used were: (1) weekly teacher evaluations of behavior; (2) daily journal entries by students; (3) the use of a self-management survey; and (4) weekly class discussion groups. A review of the literature on related research is provided and a timeline of activities is included. Success was measured by comparing the target students' past behavior with behavior during the implementation of the SMART Program. Positive affective changes in behavior and an increase in use of self-managing skills were observed. Indications of student misbehavior on report cards decreased during the second semester of the 1990-91 school year. Students engaged successfully in formal behavior self-evaluation, group discussions, and open-ended self-evaluation. Appended are related materials, a list of 16 references, and a bibliography of 25 references. (GLR)
