This data set is used to determine how students performance on prerequisite skills affect their aptitude as well as to predict students first action on a subsequent skill. The data was collected from a new feature of ASSISTments, called PLACEments. PLACEments is an adaptive testing system that traverses a skill graph when selecting test items for display. Students are assigned an initial set of skills to start the test. Students who perform poorly on any of the assigned skills are given remediation assignments. Remediations from the lowest grade skills are released and completed before the next set of remediations are released.
Prerequisite Skills data contains students responses to remediation assignments released based on the prerequisite skills on which they performed poorly. Post-rereqisite skills data contains student responses to remediation assignments released based on their performance on the initial skills.
