This document summarizes a study on developing an expert system called W-CAT (Witty Cat) to analyze educational data and generate rules to provide feedback to instructors. It describes collecting student survey data on exam preparation activities and results. Association rule learning was used to generate rules from the data, such as students who viewed review videos performed poorly on exams. The study found the rules provided useful insights for instructors. Further development of W-CAT is ongoing to automate rule generation and provide human-readable explanations of results.
