This paper reports two cases of English teaching in the computer laboratories. The instructional software corresponding to the existing curriculum was used in one case; while a combination of a cd-rom, web sites and e-cards was used in the other case. The results indicated that teachers' decision making on the instructional use of computers was strongly affected by both the personal and situational factors, and the whole teaching process generally followed that used in everyday life. It was also found that the students in the computer labs acted more restlessly and impatiently than usual due to the psychological effects of novelty and improper expectaion. According to the data collected by the follow-up questionnaires and interviews, it was found that both students and teachers had positive attitudes towards the use of computers. Moreover, this kind of personal experience was very helpful for teachers in the professional development in technology use. Based on the results from these two cases, this paper presents relevant concerns and suggestions for integrating computers into the curriculum.
