This method can be used for tracking data generated by course management systems (CMS). Currently, the only supported CMS is WebCT.
This plot is a representation of the students' social activities (i.e. in a discussion board); It allows different views on aspects like date, student or topic. The size of the point describes the intensity and the color the activity a student did (red for start a topic, green for an answer and blue for reading).
Its a representation for the cognitive level for each student. The representation is shown in a matrix. On the x-axis of the matrix are the students and on the y-axis the concept. The color of the points shows the performance.
This graph is a representation of a students overall performance. It shows his/her accesses to the content, the global accesses, the progress with the course, messages at the discussion board and submissions to quizes and assignments.
