The growing popularity of computer networks has led researchers to attempt to develop distance learning systems. However, students in network-based learning environments may need additional guidance and assistance when they encounter problems in learning certain concepts. Therefore, how to provide testing and diagnostic mechanisms in a computer-assisted learning environment is an important issue. This study presents a novel computer-assisted approach to diagnosing student learning problems in science courses. A network-based testing and diagnostic system is also implemented based on the proposed approach, which can diagnose science learning problems and offer students advice accordingly.

Keywords: learning diagnosis, concept effect relationship, computer-assisted testing, computer-assisted learning, science education
