CALL教材における英文チャンク提示法の違いが読解効率に与える効果

This study investigates the effects of different display methods of reading units on EFL college students 'reading efficiency in the CALL environment. The purpose of this study is to examine the following two questions: First, do different display methods lead the learner to a different level of reading efficiency? And second, does the same display method affect learners of differing levels differently? To examine these questions, we carried out an experiment in which we customized the multimedia display system called Multimedia Player Mint, developed by Mint Applications, CO., LTD., to create identical display environments, except for the dynamic display method of the same reading materials given the same chunking, such as 'the next reading unit will appear by clicking the mouse' or 'the reading unit will disappear after clicking the mouse'. The result shows that while a computer-assisted dynamic display method of chunking may deteriorate higher-level learners' reading efficiency, it may help lower-level learners improve cognitive skills of either reading speed or comprehension, as well as their motivation for reading activity. Further discussion and pedagogical implications for CALL material development, particularly the importance of incorporating reading efficiency, are provided in the final section.
