Cohesion, such as reference and substitution, is used to show how sentences, which are structurally independent of one another, may be linked together (Halliday and Hasan 1976) and is one of the components of coherence in reading texts. However, compared with studies on cohesion itself, there have been fewer studies made or textbooks written on teaching the comprehension of cohesion. One of the possible reasons for this is the limitations of usual textbooks and exercises. Since such textbooks and books of exercise cannot easily demonstrate how each cohesive tie is related, when they cannot establish coherence with cohesive ties in the individual study, readers are in trouble. The purpose of this study is to develop CAL (Computer Assisted Learning) courseware for reading, which takes advantage of the anaphoric relation as a reading clue. The courseware enables readers to understand anaphoric relation visually. ln addition, it is equipped with an online-dictionary. Using these functions, readers can then read the text without any assistance.
