This data is released by Professor Neil Heffernan of WPI. (c)
Professor Heffernan asks his graduate students to release their data and code to this website every time they publish a paper. He believes that makes for good science. All papers after 2012 should have a publicly available link to get the data, but if that is not true, email all the authors, and myself, asking for the data. I am glad that researchers that I don't even know are starting to use these date sets and are writing their own papers. ( If you are writing a paper or know of a paper that uses assistments data please send me (Neil Heffernan) a citation!)
With all this concern about student privacy, I liked this quote from Annie Murphy Paul "But there’s another potential danger regarding student data that is much less frequently noted: the possibility that it will sit unused, inaccessible to parents, educators, the general public—and students themselves. "

I am happy to see many other researchers using our data sets like this one that has seen a lot of papers from Stanford, Univ of Colorado, Knewton and others.
How do you read log files from ASSISTments? Since many different projects use the same variables here is the one place were we try to document the mean of the different variables.
N. T. Heffernan, 2014.
Since 2014, NSF has funded me to let researcher propose studies. We now have all sorts of clean new data sets coming out of the assistmentstestbed.org so check that our as well. Studies and their data sets are just starting to come out that have used that testbed.
