Traditional test only provides a total score and computer adaptive test (CAT) not only provides examinee's score but also estimates examinee's ability. However, both two methods have not studied students' knowledge states. Cognitive diagnostic assessment (CDA) is designed to measure specific knowledge structures and processing skills in students so as to provide information about their cognitive strengths...
The research on test equating is very important for computerized adaptive testing, test equity, item banking, and teaching quality assessing. Three new test equating methods are proposed in this paper, which are inspired by the goodness-of-fit test statistics. Monte-Carlo study shows that there are differences among three equating methods. The difference has close relationship with estimation random...
Data structure is the specialized core course for students majoring in computer science and technology, which has considerable difficulty not only in learning but also in teaching. Project-based learning (PBL) model is an important means for learning, it had been introduced to the curriculum in the past few years. We conducted project-based learning research and practice making full use of network...
