中文摘要 | 本研究目的以人本建構主義為理論基礎,探究國小五年級學生水溶液酸鹼概念的概念架構,迷思概念及其來源和概念改變機制。研究樣本以139位五年級學生進行紙筆測驗資料收集,再從中選取13位學童進行晤談等相關活動,以收集質性資料。研究方法及工具包括:紙筆測驗、晤談、三層次(three-tier test)診斷性測驗工具。 研究結果與發現如下: 一、 概念改變的分析: (一) 水溶液酸鹼性質的判斷:學童增加酸鹼指示劑概念。 (二) 學童對酸鹼指示劑相關概念的建立及應用。 (三) 學童對酸鹼中和概念認知的建立及應用。 二、 影響學童水溶液酸鹼概念之概念改變機制的重要關鍵主要有: (一) 新的資訊經個人選擇分析詮釋與理解而建構新的概念。 (二) 新的探究工具使用所造成概念改變。 (三) 新的概念引導衝擊原先概念。 (四) 新的概念與原先概念競爭的結果。 |
英文摘要 | Based on the human constructivism theory, the purpose of the study was to investigate the cognition of the concepts of "acids and bases in aqueous solution", held by the fifth grade elementary students, their misconceptions, the source of the misconceptions and mechanism of conceptual change. Both qualitative and quantitative methods were applied in this study. The qualitative research was based on the purposeful sampling method. There were 139 students participating in activities related to this research and among which, 13 students were clinic interviewed, in order to get their conception. This study is divided into three parts, they are: The use of paper and pencil test. Interviews with students. A three-tier concept diagnostic. The results and findings are indicated as follows: 1. Analysis on conceptual change on acids-bases: (1) Distinguish between acids and bases in aqueous solution's characteristic: in addition to using acid and bases' indicator to distinguish. (2) Building and applying the acid and bases indicator's relevant concept. (3) Building and applying the cognition conception of acid-bases' neutralization. 2. Mechanism of conceptual change of conception acids and bases in aqueous solution. The key factors which influenced students' mechanism of conceptual changes in this study were: (1) Construct new concept by individual analysis and interpretation on newly selected data by. (2) Conceptual changes due to use of new experiment tools. (3) The guidance of new concept against original concept. (4) Result of new and original concept competing against each other. |
