Garrett Marc Dancik, Amruth N. Kumar · 2003
We have developed n web-based tutor for teaching and testing counfer-controlled loop concepts in C++. The tutor is designed to promote problem-based learning. It repeatedly generates problems, grades user's answers and providesfeedback about the correct answers. This paper describes the design ofthe tutor. outlines a test that we used to evaluate its eflectiveness. and presents the results of he test. The test confirmed our hypothesis I hat using the tutor helps improve student learning. The improvement is stofistically significant. This tutor can be usedforpraciice or testing in Computer Science I.
