中文摘要 | 隨著學習與教學之觀念轉變,建構知識的主體已由過去以教師為主體轉成強調自我建構的以學生為主體。因此,數學的學習目標便在於強調學生能夠真正地理解(understanding)數學知識,而不是背誦之機械式記憶。本研究為質性研究。研究主要目的是在研究者所佈置的合作學習情境中,藉由Posner(1982)概念改變模式瞭解三位學生在此情境脈絡中如何透過彼乙間相互的對話,造成學生個體內部概念生態形成不穩定的狀態,促進學生個人概念改變,進而達成概念學習之成效;再以Toulmin(1958)論證模式分析學生在進行對話的過程中的論證表現。研究對象選取研究者課室中的三位高一學生。蒐集的資料為研究參與者學習歷程之錄影帶轉錄文本與學習單。研究結果發現:教學不能只是告知學生或向學生展示知識,教師必須要讓學生經由自己的思考與推理、對話溝通去創造意義;唯有讓學生概念生態產生不穩定的狀態下,學生才會去改變自己既有之概念結構。再者,學生論證的取向包括直觀經驗與實例之論證、形式理論之論證。因此,教師除了盡量為學生佈合適之論證題型外,尚須鼓勵學生多思考、辯證以營造論證之氛圍,方能使課室中的學習更為意義化。 |
英文摘要 | This paper reports three first-grades of senior high school students' performances on the tasks about integral number. This paper is a qualitative research. The first purpose of this study was using Posner's (1982) conceptual change model (CCM) to inquiry how the three first-grade of senior high school students make others' conceptual ecology becoming unbalance by their dialogues and to bring their conceptual changing under the cooperative learning context. The second purpose of this study was using the framework proposed by Toulmin (1958) to inquiry the three first-grade of senior high school students' argumentative performances. The collected information include the videos coding data recorded the process of the three students' learning and the individual student's papers. The main results were: (1) The three students would change their conceptual framework after their conceptual ecology becoming unbalance through communicating, thinking and reasoning with each other. (2) The approach of the three students' argumentation included visual experienced argumentation, using example argumentation and formal theory argumentation. Above all, the teacher should construct a learning context in which students can thinking, having argumentation and meaningful the mathematical learning. |
