Performance Evaluation of an Active Learning System to Improve Students Self-Learning and Concentration

In our previous work, it has been shown that the students can improve the learning process by using smartphones. The professors of the university cannot provide the information to satisfy all students because the quantity of knowledge of each student attending a lecture is different. Therefore, for the lectures of a higher level than intermediate level, the students should study the learning materials by themselves. In the previous work, we presented an interactive learning process in order to improve the students learning motivation and the self-learning time. To improve the progress speed of a lecture, we proposed an Active Learning System (ALS). Also, we introduced a procedure for Self-learning by adding some functions in order to improve the efficiency of the Self-learning. In this paper, we performed experimental evaluation of our ALS. The results showed that the proposed ALS can improve student self-learning and concentration.
