Review:
Very nice paper that describes the HalVis system. It begins with a discussion of prior disappointing results in the evaluation of pedagogical effectiveness of algorithm visualizations. It goes on to argue for interactive visualizations that integrate (i) multimedia descriptive information about the algorithm, (ii) questions to students about the algorithm, and (iii) the visualization itself. Several studies are then presented that attempt to compare the performance of students using text vs. Halvis, lecture vs. Halvis, and XTango vs. Halvis. In general, Halvis performed significantly better.
