This study investigates the use of adaptive teaching strategies to promote learning in cooperative learning settings. The Biology Sleuth, a problem-based learning environment, was developed as a testbed to vary the distribution of critical resources and to examine the use of teaching strategies and their effects on group dynamics and individual learning. Students work in small groups, aided by various resources including a knowledge-base, each other, the software, and the teacher. This study examines the effects of applying two different teaching strategies and suggests that these strategies can have a large impact on both group dynamics and individual learning. A 35% improvement (p
