This study aims： （1） to describe the students＇ perception of the use of Interact as teaching media in learning reading comprehension; （2） to depict the students＇ perception of the importance oflnternet to access information; and （3） to explain the students＇ frequency to access Internet. This study uses the descriptive method to reveal the research problems. A questionnaire is used to collect the data. It consists of 20 questions with five options to reveal the students＇ perception of the use of Internet. The questionnaire is distributed to 120 students who took reading subject at the University of Muhammadiyah Malang. The study shows that （1） The students＇ perception toward the use of Internet to improve Reading Comprehension subject is positive; （2） According to the students, the use of Internet to access reading materials is very important; and （3） The students frequently access Internet to find the reading materials.展开更多
