Wheelspinning


Abstract

This project concentrates on three main goals. The first goal is to develop additional contents for ASSISTments system targeting fifth, sixth, and eighth graders. The second goal is to determine whether five, seven or nine skill-master problems with directive feedback including hints, and explanations are the most effective in detecting a wheelspinning. This goal was resolved by a separated study which was conducted by Tuan Le. The results of this study was then incorporated in our study to achieve the last objective of our project which is to provide extra helps for the wheelspinnings and to investigate their effectiveness compared to directive feedbacks. Each problem was created with identical content, yet presented to students in one of two ways: with directive feedback or with extra tutoring videos. A study was then conducted using these problems sets to acquire data with the purpose of determining which method is more effective. For each problem set, students were randomly assigned in either the experimental group or the control group, which were exposed to either extra video helps or directive feedback respectively. The data was then collected and analyzed. In conclusion, although our study was inconclusive about the impacts of tutoring videos on wheelspinnings, many issues associated with the study were addressed throughout the project.
