本研究旨在透過等號關係概念理解課程的設計,實施教學,探究二年級學童在教學歷程解題與轉化的表現,了解其對等號概念發展與理解的情形。樣本為屏東縣某小學7名學童,以個案研究方式進行,應用自編測驗工具蒐集資料,以量化方式分析、比較學童在測驗表現情形,配合課室對話、訪談,以質性方式闡釋學童互動之言說和行動。課程內涵分為四項活動進行,教學時間為160分鐘。 經過教材設計、教學實驗與測驗結果等歷程獲得的結果分析,證明本研究之課程設計與教學實施可以提升學童等號概念的理解。研究發現:(1)學童在課程教學前,大多數採用運算的觀點解釋等號意義,但在解釋上有所錯誤。(2)透過數量推理課程活動的實施,配合師生實物操作互動,受試學童可建立多元解題技巧和策略,強化等號概念理解的轉化。(3)透過後測及訪談,發現學童能夠建立合理的等式概念結構知識與能力。 研究者依據研究發現,提出相關建議,提供未來等號概念理解研究與教師教學實務參考。
The research here presents the result of a case study examining the effects of curriculum design and instruction of seven second graders as they participated in a equal sign conception understanding project carried out by the author. The researcher's goal was to explore with what interpretation and with what strategies the students were able to work out an equation solution. The study analyzed 4-period instructions to determine the impact on students' ability to explain the meaning of equal sign. Results indicate that the curriculum design and instruction device that led to positive shifts in students' understanding of equal sign conceptions.
