Summary:碩士 === 中原大學 === 應用數學研究所 === 102 === Abstract In all material covered in high school mathematical class, “proof question” has been recognized as a highly efficient mean in logic reasoning training. Unfortunately from practical teaching experience, such training seems to be the Achilles’ tendon in modern mathematical education. Guide line is the commonest solution in graphic proof question. The purpose of this study focuses on giving appropriate guide lines in soling graphics proof questions, while regains the importance of proof question, helping high school students meet the requirement of new “nine years mathematic education architecture”: learning logic reasoning from graphics. Topics covered in this study are designed for students of nine grades or above. The question becomes: what to do with guide lines, in solving graphics proof questions? This study may not provide reference for all type of proof questions, but for graphics proof questions offers guide line-based solving strategies. By walking through all the material covered in this study, a known fact is that solving graphics proof question is nothing more than using guide line, properties of graphical objects themselves or their extended ones. Salted with graphic theories and logic reasoning, a claim in graphics proof question can be determined, when all the prerequisite knowledge is well prepared. Obviously one proof question could be solved in various approaches. With further experience and richer prerequisite knowledge, better solution could be found in time. Teachers are expected to understand students’ learning progress and help them build fundamentals in individual base. So most of students should be able to get involved and discuss among piers.
