Abstract

Training students in the discernment ability is an important task in distance education. To improve the training results, this chapter makes the following contributions: (1) suggests Web courseware on controversial social issues with different viewpoints for discernment training; (2) constructs the courseware for Discernment Ability using a method called DRPA. This method is presented with five algorithms, for extracting representative phrases, calculating characteristic array, determining the threshold array, objective judgment and subjective judgment; (3) proposes and proves that a new concept, called Gymnastics Threshold, is more accurate than traditional threshold; and (4) uses extensive experiments to show that DRPA is much more efficient and accurate than traditional method.
