This manual on developing teamwork at the computer provides cooperative learning activities for grades K-10 which promote the development of academic, computer, and social skills. The manual is divided into three sections: (1) "Getting To Know Each Other"; (2) "Group Cohesion"; and (3) "Group Problem Solving." The first group includes 10 activities designed to set the stage for cooperative work in a team as students become acquainted with each other and share information about themselves. The second group provides 10 activities designed to help students establish a team identity. They are also intended to develop communication, trust, and a feeling of belonging which will enable a group to work together later with subject area content. The eight activities in the third section are designed to foster students' thinking together and developing such skills as listening to others and asking questions. Students focus on a particular problem and participate in a successful solution. Each activity includes a specification of grade level, time requirement, material requirements, and student prerequisites; an introduction to the lesson; procedures for group tasks, closure, and extension; teacher notes; and student worksheets. The appendixes include a directory of software requirements for each activity, including the publisher's address; and an order form for this book. (GL)
