碩士 === 國立清華大學 === 數理教育研究所碩士在職專班 === 107 === This study is Reasoning-and-proving opportunities in elementary mathematics textbooks : Algebraic.It is mainly to discuss how many questions of Reasoning-and-proving opportunities for students in K , N , H editions. Our research object are elementary mathematics textbooks which were adopted in 2008 curriculum guidelines.This research method mainly adopted the“content analysis method”.The research units are analyzed and compared by the major problems in elementary mathematics activities, and class with Reasoning-and-proving opportunities, purpose of Reasoning-and-proving problem, type of argument elictited. The results show the number of Reasoning-and-proving opportunities in Algebraic：the K edition has the most number of Reasoning-and-proving opportunities, the second is the H edition, the lastest is the N edition. The results show the purpose of Reasoning-and-proving problems in three editions：they all have the highest proportion of the "making claims" category, followed by the " making claims & justifying claims" category, and the " justifying claims " has the lowest proportion. The results show the type of argument elicited in three editions：they all have the highest proportion of the "generic example" and " rationale " category, followed by the "demonstration" category, and the " empirical " has the lowest proportion. We do hope that the findings of this study can be used as a reference for fufure textbook development and revision.
