Interactions between students and instructors are crucial to the success of learning and teaching. However, such interactions are limited in large classrooms (e.g. STEM courses and MOOCs). We present CourseMIRROR (Mobile In-situ Reflections and Review with Optimized Rubrics), a mobile system that prompts students' self-reflection and in-situ feedback to enhance the interactions. CourseMIRROR uses automatic text summarization techniques to aggregate students' feedback and present the most significant ones to both the instructors and the students to help them understand both difficulties and misunderstandings encountered. In two semester-long pilot deployments involving 20 participants, we received positive feedback from both students and instructors. We highlight major findings as well as the lessons learned.
