| Summary: | 碩士 === 國立臺南大學 === 數學教育學系 === 93 === This study is to develop an Internet computer assisted instruction（CAI）based on applying multiple units system in multiplication arithmetic, and explore the validness of the system. Furthermore, evaluating the application of the Internet CAI is to offer the reference as setting up complete system in the future. The study proceeds the method that tests the experimental teams and the controlled teams, before and after using the Internet CAI. The examinees are the 78 students in two classes of grade four in the primary school in Tainan City. The material is the integer multiplication unit in grade four in primary school. After analyzing the collected written examination, the study has found out the important conclusions as follows:
1. For low level score students in learning achievement, those who have received the Internet CAI are superior to those who have only received traditional teaching in multiple units multiplication problems.
2. For the learning of the conservation concept in multiple units multiplication problems, those who have received the Internet CAI are better than those who have only received traditional teaching.
3. After the experimental teaching, the result has shown that the Internet CAI based on applying multiple units system in multiple arithmetic is a valid and efficient teaching model.
4. It is helpful for students to use the little white board in this system to provide the tool to solve the questions.
5. Using the system can stimulate students’ learning motivations and gradually like mathematics; furthermore, appreciate the fun of learning mathematics.
6. Thanks to the Internet CAI popular with students, they may learn positively, acknowledge the content in the material, and feel more self-confident in the meantime. Therefore, this system can show that the students have the positive learning attitude.
The study is designed to offer the references to the schoolteachers and the CAI programmers. Furthermore, it can also provide many constructive suggestions for the future research and teaching.
