(.): The paper is dedicated to computeraided assessment of multistep problems provided by interactive modeltracing intelligent tutoring systems. An approach is suggested for determining which formulas could students formula be derived from. In some cases, the suggested approach can discover whether students step is an imitation. The suggested approach is a part of the algorithm which calculates students solution progress.
