Besides material from the first edition, this book includes more recent research on cooperative learning as well as updated ideas, techniques, and bibliography. The book provides discussion on how to form groups, design group projects, and assess group work. The majority of the book, however, is dedicated to examples of learning activities suitable for group work at all grade levels. For instance, one activity explores how to use transformations to graph parabolas. Three group members each take an equation of a parabola that has been shifted left or right by a constant.
Students compare and discuss the results of the transformations.
A bibliography of resources related to cooperative learning is included.
