This file contains data from ASSISTments' non-Skill Builder problem sets, includes Liner and Random order and other problems set types.

The differences between Liner and Random order problem sets are:

• Linear - Student completes all problems in a predetermined order.

• Random - Student completes all problems, but each student is presented with the problems in a different random order

In you are using this data set in a publication then please site this exact (https://sites.google.com/site/assistmentsdata/home/assistment-2009-2010-data/non-skill-builder-data-2009-10) URL so folks can know which assistment data set you used.

If you are using it in a publication, please make reference to ASSISTments by citing our most commonly used paper to reference the ASSISTments system. (To be clear the paper below is from 2009 and does not use this data.)
