Formative Evaluation of the HyperProb Tutoring System for Probability Problem-Solving.
O'Connell, Ann Aileen; And Others
HyperProb is a Hypercard tutoring system designed to help students develop an effective step-by-step schema for solving probability problems. With this program, students are able to select areas they wish to study via hypermedia links and develop an understanding of terminology and procedures at their own pace with continued reinforcement. Nine graduate students in counseling assisted in the HyperProb evaluation by using the tutor and attempting to solve seven probability programs. They then answered questions about their satisfaction with the content, pace, depth, and navigability of the program. Overall, students reported liking the self-paced nature of the tutor, but had difficulty linking to the next unit until after one was completed. Results indicated that most students felt it would be optimal to have a teacher available while using the tutor, rather than having HyperProb as a "stand alone" instructor. Researchers not only incorporated suggestions back into the program but also studied errors made on the seven problems to shed light on the program's possible weaknesses. A copy of the seven probability problems and a summary of common errors are appended. (BEW)
