Kyung Won Kang Advisor : Prof. Nam Gil Kim Major in Mathematics Education Graduate School of Education, Chosun University

The purpose of following research is to get an idea how middle-school aged students understand and study about the operations with negative integers. Two questions have been set to achieve the purpose of this research.

1. Are students able to explain the operations with negative integers formulas in detail or through detailed models. 2. What types of difficulties do students experience when dealing with the operations with negative integers.

The research was conducted for 100 second and third year middle school students of 'S' middle school in Gwang-ju. First year students were excluded as they were not yet thought about positive numbers. The two types of examination papers were used to find out the level of understanding on the theory of the operations with negative integers. Interviews had been carried out individually in detail for what is hard to get from the examination. Not many students could not explain the process even though most of them were able to calculate the formulas. The development on the negative integers needs to be investigated for students to understand.
