Learning fraction concerns both concrete and abstract concepts, and this system carries out a series of remedial instructions to correct those students’ misconception with the instructional Flashes made based on mistake classifications, providing students with a learning circumstance free of time limitation. For teachers, this system not only helps them find out the students’ misconception instantly, but helps them carry out remedial instructions to these students in due time. Therefore, this system can shorten the time that the teachers spend on remedial instructions and lighten their workload arisen from remedial instructions, giving them more time to embark on teaching researches and to increase teaching effectiveness. The researcher finds out in this study that using this system to carry out diagnosis tests and remedial instructions can achieve the following goals: (1) to diagnose the students’ misconception instantly and accurately for teachers’ reference; (2) to carry out remedial flash instructions to students timely and effectively according to their misconception classifications; (3) to improve the students’ learning effectiveness; (4) to shorten the time that the teachers spend on remedial instructions and lighten their workload arisen from remedial instructions.
