Visualization of the Student’s Progress in Adaptive Educational Systems

Adaptive Educational Systems (AES) constitute the broad domain of systems and courseware that are able to tailor their content to the individual needs and traits of the learner. For example, the system can automatically restructure a course in order to make it more suitable for the learning style of the student, highlight the parts in which the student did not perform well (hence should focus on), or recommend the content that matches the individual learning goals of the student. In order to achieve these adaptation effects, the system must have a learner model providing the information about the student’s knowledge, performance in the class, learning goals, interests, etc.

The main goal of this thesis is to adapt the IntrospectiveViews interface developed in our earlier work [ 1] for visualizing the courses the student is taking and the progress she has made. The interface should allow the student to get an overview of the lectures constituting the course and the content of each lecture. It should also indicate the topics that have been already covered by the lecturer and provide the information about the student’s progress with respect to each topic. In addition to the overview, the interface should provide convenient access methods to the content of each lecture, namely, the lecture slides, readings, exercises, assignments, and quizzes. Finally, the interface should enable the student to compare her own progress to the progress of the entire class and individual students. The scope of this work includes, but is not limited to a literature review in related research areas (AES, user modeling, information visualization, and usability), prototyping, usability testing, and implementation of the interface in Java. This work will be done in close cooperation with the research group of Peter Brusilovsky from the School of Information Science at the University of Pittsburgh.
