Discussion: Pick out two representative students

To conduct a more in-depth analysis into how students in the two conditions (VA and VB group) may have navigated through the activity sequence differently, we need to select one representative student from each condition and analyze their log data.

We first selected students who visited visualization step more than once and also stated that the visualization was helpful (VB) or could be helpful (VA). There are 26 students (6 students are in VB group, and 20 students are in VA group) meeting the first requirement.

Legend (Note: The first six cases are students in VB group and the rest cases are students in VA group; The width of the rectangles represent the time duration in the steps; Hover the color blocks and information of the block will be shown in X step: Ys, which means that the student spend Ys on step X.)
