| 中文摘要 | 本研究目的在探究國二學生對人體循環系統概念的另有架構,所採用 的方法為半開放式的紙筆測驗,先對432位國二學生施測,將學生的作答予以歸 類,並找出多數學生所共有比較常見的另有想法類型,然後從各列類型中找出40 位具有代表性的學生進行深入的晤談。對於紙筆測驗資料和晤談個案資料的分 析,都先條列出各種想法,再加以合併及歸類,最後推斷其共同根源或信念,整 理出另有架構。研究結果顯示國二學生對於人體循環系統概念所具有較共通的另 有架構有:1.以紅血球或血紅素為人體運輸功能的主角。2.以自血球為人體防衛系 統的中心。3.以血管的厚薄粗細來推斷血管彈性的大。4.認為血流方向沒有一定 的規範,不受循環構造(如瓣膜)的限制。5.以血管類別,決定所帶血液新鮮與否 為基本原則,再推演其循環系統概念的架構。 |
| 英文摘要 | The purpose of the study was to investigate the alternative frameworks onhuman circulatory system conceptions which were held by the eighth grade of student. t first, a semi-open-ended paper-and-pencil test was given to 432students. Students'responses were classified is order to find out the popularalternative conceptions. Forty representative students samples were chosen tointerview. he data were analyzed from both paper-and-pencil test and individualinterview which showing various kinds of students'explanations. These conclusionwere subsequently combined into several categories, each category representingan alternative conception held by a number of students. The common origins orbeliefs were developed from the alternative conceptions. Several importantalternative frameworks were shown:1.The red blood cell or hemoglobin worked as the main role of human transport unction.2.The white blood cell served as the center of human protective system.3.To judge the vessel elasticity from the thickness and diameterof vessels.4.The direction of blood streaming haven't any specific rules, and was not estricted by circulatory structure (e.g. valve).5.By the vessel types to determine whether they contain fresh blood or not, and hen to infer the framework of circulatorysystem conception. |
