碩士 === 國立臺南大學 === 數學教育學系碩士班 === 93 === Based on three sixth-grader subjects who did not do well in mathematics at school, the purpose of this research is to investigate how the students improve their performance in fraction multiplication after receiving Excel-based remedial instruction. Also, the researcher seeks to further understanding and analyze how the multiple representations materials influence students’ learning and to provide reference for other teachers. The subjects in the study are from the Kaohsiung elementary school where the researcher is serving. The cases received the remedial instruction with the “multiple representations” teaching mode under visualized computer setting. The data adopted in this study including students’ scores in tests before and after they received the remedial instruction, semi-structured interviews, and study journals. The analysis of the data focuses both quality and quantity. The results of the research can be concluded as follows: I. After receiving the Excel-based remedial instruction under visualized window setting, the students are proved to have better understanding of fraction multiplication: 1.They have learned how to solve the five major math subjects and the rules of symbolic calculation related the multiplication of fraction. 2.They have learned the unit relation among the three different levels of the multiplication of fraction. 3.They have become familiar with the concept of unit fractions and unit quantity. 4.They have learned the skill of partition. II. After receiving the Excel-based remedial instruction under visualized window setting, the students have improved their logical thinking. III. After receiving the Excel-based supplementary education under visualized window setting, related to the multiple representations topics has the following effects on students: 1.They have learned to translate among different representations. 2.They can understand the inner transformation of the representations. 3.They have learned to solve problems by looking for clues in the representations. IV. After receiving the Excel-based remedial instruction under visualized window setting, they have changed their attitude toward studying and showed more interest in mathematics. V. The Excel-based remedial instruction under visualized window setting has certain characteristics that can help students to learn: 1.The computer-based supplementary education can record and keep the process of a student’s learning and operation on the representations system. 2.Students can change the numerals given in the questions and do repeated exercises to find out the rules of calculation on their own. 3.When the students put in a wrong answer, the system will allow them to try as many times as possible before they get the right answer.
