Evaluating Feedback Efficiency in Learning Notification Express Delivery Service

1 Abstract: Giving students suitable feedback information is one of the research issues in CAI. This research tries to evaluate if feedback did help in the course. For this purpose, this paper constructs an e-learning environment with feedback mechanism based on the previous research (10). Students' learning activity will be recorded by the system and suitable feedback will be sent to students via short message or e-mail. There are four fifth grade classes participated the experiment. The experiment analysis contains two parts, the first one is evaluating the feedback efficiency for all groups; and the second part separates the students into three clusters based on their academic achievement.
