The purpose of this study is to investigate the types of concepts about atmospheric pressure of middle school students and to design a new method to improve students' understandings on atmospheric pressure. The second grade students of the middle school has been selected and examined their pre-concepts on atmospheric pressure through questionnaires and interviews. Two groups of students have been taught using the second grade science textbooks and experimental methods designed from this study, respectively. The results suggest that we need to develope various teaching methods that can improve alternative concept as well as experimental tools that can help students understand difficult scientific concepts. The reason is that once alternative concept is occupied, it is extremely difficult to fix it. In addition, the proposed experimental methods are effective in establishing the concept and understanding on atmospheric pressure.
