| Summary: | 碩士 === 國立臺灣師範大學 === 資訊教育研究所 === 89 === This study proposed a new approach that combines IRT, computerized adaptive testing, and dynamic assessment. The purpose of proposed method is to maximize the zone of proximal development more effective, more efficient, and more accurate than the traditional dynamic assessment. Thus, the Interactive Polynomous assessment system (IPAS) was designed to prove the effectiveness and efficiency of the proposed method. The IPAS includes two subsystems: the computerized intervention subsystem and the CAT subsystem based on the GR model. Subjects were randomly assigned into three treatment groups: the experimental group which practice with a computerized intervenient system, the controlled group which practice themselves without any interventions, and the compared group which practice under direct teacher supervision, also called conventional dynamic assessment. The performance of three groups was compared. The performance of experimental group was higher than the other two groups, but not significantly. The results of this study lead to three conclusions. First, IPAS can provide adaptive interventions to students during measurement. Furthermore, it is more convenient and economical. Lastly, students enjoyed this system. To put it briefly, the proposed method improved traditional dynamic assessment successfully.
