The document discusses using learning analytics to support just-in-time teaching through a system called classON. classON provides personalized monitoring of students, awareness of student progress and questions for teachers, and analytics to help teachers more efficiently answer questions and ensure student understanding. An experiment found that classON helped reduce waiting times for student questions to be answered and increased the number of questions solved compared to traditional teaching methods without analytics support. The results validated that classON fulfilled requirements to help both teachers and students make the most of learning sessions with limited resources.
