Trend of research in e-learning for the purpose of education quality improvement

There exist two types of e-learning systems. One of them aims to improve the education efficiency. Distance lecture system and WBT (Web Based Training) belong to this type. In these systems, interaction between educators and learners become lower than in the conventional classroom teaching. Therefore, these systems cannot improve the education qualities. The other aims to improve the education qualities. The e-learning systems in this type, which are newly developed, notify the educators of the learners' conditions in real-time and support educators' activities. One of these systems automatically lectures using WBT and notifies the educators of the stalled learners and their learning data (exercise answers and questions). Depend on these data, educators concentrate on the education to each stalled learner. Another system is used for the lecture for large number of learners. This system notifies an educator of the learners' exercise advance in real-time. Depend on the data, the educator judges if he gives advices to the learners and if he explains the next item. The e-learning systems have another merit that educators can improve the education methods by analyzing the accumulated education log. As this field is on the way of development, future study is anticipated.
