Abstract
With the recent rapid progress of computer technology, researchers have attempted to adopt artificial
intelligence and use computer networks to develop computer-aided instruction systems. Meanwhile,
researchers have also attempted to develop more effective programs to test and enhance the learning performance of students. However, conventional testing systems simply give students a score, and do not give
them the opportunity to learn how to improve their learning performance. Students would benefit more if
the test results could be analyzed and hence advice could be provided accordingly. This study proposes a
conceptual map model, which provides learning suggestions by analyzing the subject materials and test
results. A testing and diagnostic system is also implemented on computer networks based on the novel
approach. Experimental results have demonstrated that the novel approach benefits students and deserves
further investigation.
