I met David Camp, a vice president of LearnStar while waiting for a bus to my hotel at NECC. LearnStar is an interactive, competition format, real-time group interactivity software program for classrooms. All while the teacher remains in complete control. According to a study report the LearnStar site links to, students who used LearnStar in a controlled study did 65% better on their Calculus I final exams than students who did not. That’s a good start. I haven’t used the product. What results have you found?
