中文摘要 | 本研究目的為運用POE策略探究中小學生對於物質之可燃性的另有概念,研究樣本包括彰化縣之小六(68人)、國二(73人)以及高一(85人),每年級各二班共計226人,以可燃的方糖與不可燃的雙氧水做為讓學生預測是否燃的物質。研究結果發現學生普遍持有「液體不可燃」、「硬硬的固體無法燃燒」、「物質含氧可以燃燒」、「物質熔化不會燃燒」、「可供食用的物質不會燃燒」、「物質加熱冒煙是燃燒」等與科學家不同的概念。年級越低的學生的想法受到生活經驗及直覺觀點的影響有越明顯的傾向,而年級越高的學生受學習經驗的影響則有越明顯的傾向。研究結果也顯示學生較缺乏應用解釋的能力,因此建議在教學設計上應該多給學生運用知識的機會而不僅是學習定義型的概念,以使學生不僅學習到陳述性知識(declarative knowledge),也能學習如何運用程序性知識(procedural knowledge)。 |
英文摘要 | The purpose of this study was to explore students' alternative conceptions of combustible matter by using the predict-observe-explain (POE) strategy. The subjects included 68 6th graders, 73 8th graders and 85 11th graders (two classes fro each grade, total N=226). And the matter used was cubic sugar (combustible) and the peroxide hydrogen. The results indicate students hold some alternative conceptions: liquids were incombustible, solid maters were incombustible, combustible matters should include the element of oxygen, confuse melting and combustion, all of the foods were along incombustible matters, smoking was necessary phenomena of combustion. The results also indicate the daily experience has obvious effect on lower grade's idea, and school learning has obvious effect on higher grade's idea. Most students lack the ability of explanation, however, we should provide the opportunity for applied knowledge to explain natural phenomena in teaching that enhance for learn of procedural knowledge, not just learn of declarative knowledge. |
