For inclusion of students with disabilities to work successfully in schools, a sense of community among faculty and students, a shared mission, and the ability to successfully collaborate with others are essential. Activities to promote collegial relationships among faculty should be a part of each inclusion team's plan for implementing inclusion at a particular school site. Group building activities can help faculty members become better acquainted with each other, nurture respect for personal differences, build awareness of professional strengths of team members, provide an opportunity to practice skills needed to work together, and provide opportunities for team members to share what has been going well. Essential components of group building activities, which are similar to cooperative learning activities, include: working in heterogeneous groups, promoting positive interdependence, providing success, rewarding the group for success, and encouraging individual accountability. To generate a classroom climate conducive to acceptance of individual differences and cooperation, group building activities involving students are also needed in classrooms where inclusion will take place. Two sample group building activities are described. (JDD)
