jGRASP: a lightweight IDE with dynamic object viewers for CS1 and CS2

The jGRASP IDE provides new object viewers that automatically generate dynamic, state-based visualizations of objects and primitive variables in Java. Multiple synchronized visualizations of an object, including complex data structures, are immediately available to users from the jGRASP debugger window or object workbench. Initial classroom use has demonstrated the object viewers' potential as an aid to student learning, while future research will explore their utility through controlled experiments.
