| Summary: | 碩士 === 臺中健康暨管理學院 === 資訊科技研究所 === 92 === The main objective of this research was to establish a computer-adaptive test based on the knowledge structure, to develop a knowledge structure-based online computer adaptive diagnostic test system and the research object was the fourth graders and their performance in the time unit of math. After conducting the online adaptive diagnostic test, students’ errors were evaluated through the test system for fast and accurate assignment of students to appropriate reinforcement classes to facilitate the following instruction. After taking the test, students were surveyed through the online questionnaire and each design of the system was explored to find out students’ response to the computer-adaptive diagnostic test.
The knowledge-based computer-adaptive test mode brought forth in this research was a result of experts and teachers’ analysis on the unit content, establishment of unit knowledge structure and design of questions based on the knowledge structure. The test mode enabled students to know their weakness in the unit right after the test and made reinforcement easy to be carried out, which in turn greatly decreased teachers’ burden.
This research showed the following results:
1.The knowledge-based computer-adaptive diagnostic test could effectively save the time and questions needed in a test.
2.The computer-adaptive diagnostic test whose questions were selected based on the expert knowledge structure could assign students to appropriate reinforcement classes with their test results quickly and accurately.
3.Computer-assisted tests were new to students and received positive responses from both boys and girls with no significant differences.
