Covariate File - A collection of useful covariates for the students who participated in your study. This file includes student level variables (i.e., gender), class level variables, (i.e., homework completion rates), and school level variables (i.e., urban city). Click here for a tutorial on how to link this file to your experimental data.
Action Level - One row per action per student; the finest granularity. Students participating in your study have performed 884 actions (e.g., beginning problems, attempting to answer problems, asking for hints or tutoring, and eventually completing problems).
Problem Level - One row per problem per student. Students participating in your study have completed 249 problems. The flow through a single problem incorporates many actions, resulting in a coarser data file (fewer rows).
Student Level - One row per student; the coarsest granularity. Columns are laid out in opportunity order to depict the student's progression through the problem set. Problem level information is expanded to one column per problem per field (column heavy).
Student Level + Problem Level - One row per field per student. Columns are laid out in opportunity order to depict the student's progression through the problem set. This is an alternative view of the student level information (row heavy).
