Update: Duplicated data records have been detected in the data sets that located at above links. A corrected version can be found here:
This file contains one row per student-problem (i.e. if student S answers problem P which has two skills, the two skills are collapsed into the format skill1_skill2 and represented in a single row):

Skill builder problem sets have the following features:
Questions are based on one specific skill, a question can have multiple skill taggings.
Students must answer three questions correct in a row to complete the assignment;
If a student uses the tutoring ("Hint" or "Break this Problem Into Steps"), the question will be marked incorrect;
Students will know immediately if they answered the question correctly;
If a student is unable to figure out the problem on his or her own, the last hint will give the student the answer;
Currently, this feature is only available for math problem sets.

More info is available from this year school year here.
We recently in 2020 published a KDD paper with Andrew Lan and Ghosh at UMASS.
We are going to link this soon.
Dr Heffernan is aware of a some paper that have used this data set. He tries to keep track of such studies. He is aware of some work and he has a list here:

If you know of a paper that uses this data set please send me a citation and link to the paper as I want to know and report to my funders.
We also have the 2014-2015 skill builder data set here.
