A framework to search better series of lecture improvement

To increase learning quality, instructors and learners must make efforts toward improving their lectures. As a start, instructors and learners need to share context and know-how, and cooperate for lecture improvements. We propose a framework for capturing learning states and context, and for better searches for lecture improvements. Specifically, this framework records and analyzes performed actions in lectures that contains efforts toward improvements, their context, and the result of the actions as described in lecture evaluations.
