A Feedback Effectiveness Oriented Math Word Problem E-Tutor for E-Learning Environment

E-Learning is gaining more traction as it is accepted and used by more students, as it provides time convenience, cost effectiveness, and location flexibility. E-Learning's key weakness is lacking of a cost effective way to support instructors to provide synchronous feedback to students. In addition, the help provided is usually not in real time and is missing an instructor's influence to a student's affective status in the feedback, which creates a practicality gap between e-Learning and feedback effectiveness. This paper proposes an e-Tutor framework for math word problem, and discusses various aspects of feedback effectiveness which is the central design concept of the e-Tutor.
