The Promise and Reality of Web-based Tutoring

Professor David E. Pritchard




Web-based intelligent tutors offer interactive tutoring for individual students, such as pedagogically useful responses to their wrong answers and hints and simpler subproblems upon student request.  Our research shows that one such tutor (see teaches twice as much per unit time as hand-graded written homework.  Feedback from the students can reveal specific student mistakes and misconceptions, providing rich data allowing authors to improve their content and also shows class difficulties on each problem for JITT.  Our research shows that assessing the process of solution can give a detailed profile of student skills, allowing targeted tutoring.  Splitting the class into two groups that work the same problem after one group is given a tutorial has allowed us to measure the amount of learning per unit time from the tutorial.
