Resize: ITS Learning Behavior

The Visualization

This work is an exploration of the Resize Feature using data from students solving math problems.

The Data Set

This data set shows a summary of student behavior during mathematical problem solving within an intelligent tutoring system (ITS). The system records behavior such as time to solve each problem, number of attempts, number of hints shown, and correctness. This data set also has corresponding MCAS scores for each student (MCAS is a state-wide standardized mathematics test for students in Massachusetts).

Data Sources
