Rivers et al. canonicalize student programs using equivalency-preserving transformations (renaming variables, reordering binary expressions, inlining functions and so on)~\cite{rivers2015data-driven}. We use their canonicalization as a preprocessing step before extracting patterns. -The next section describes TREs and AST patterns, and gives a brief quantitative evaluation to show that patterns can be used to discriminate between correct and incorrect programs. Section~\ref{sec:rules} describes our modified version of the CN2 rule-learning algorithm, and analyzes student solutions to two programming exercises in terms of such rules. The last section outlines the directions for our future work. +The next section describes TREs and AST patterns, and gives a brief evaluation to show that patterns can discriminate between correct and incorrect programs.
