CourseMIRROR used text summarization techniques to summarize the students’ responses. The detail of the summarization algorithm is reported by Luo & Litman (2015). The summarization algorithm used by CourseMIRROR is evaluated on an engineering course corpus consisting of handwritten student reflections generated in response to instructor prompts at the end of each lecture, along with associated summaries manually generated by the course TA (Menekse et al., 2011).
