本研究目的在探究國小教師對於環境議題之相關訊息的處理方式及所作的抉擇判斷。選用的三個環境議題皆具備下列特性:為受到關注的公共議題,具有爭議性;議題所牽涉的訊息是複雜且多元的;議題之判斷可能與個人的價值觀和感受有關。本研究工具為開放式問卷,各議題內容包含概述和正反兩方的論述,撰寫方式則強調:議題正反兩方的論點舉證比重相當且相互對應;對議題的理解判斷不一定需要深入的或技術性的知識,透過設計者的陳述即可了解議題的癥結並做抉擇判斷。問卷施測對象共計180位任教於北、中、南各區53所國小的教師,採滾雪球抽樣法,最後共回收113份有效問卷。分析不同學科背景的教師對議題立場的選擇、訊息採用的偏向以及抉擇判斷的依據的差異情形。再以目的性取樣選取其中23位接受半結構式晤談,以找出受測者之核心思想和考量議題論點的依據,並歸納其訊息處理和抉擇判斷模式。本研究結果可提供議題教學設計之參考,並對環境教育師資培育課程提出建議。
This study mainly analyzed elementary teachers' information preferences and decision makings on three environmental issues. These three particular issues were identified and selected because: (1) they raised controversies by the public in recent years; (2) they contained complicate information or inclusive evidence; and (3) They allowed people to make judgments with personal values and experiences. An open-ended questionnaire, in conjunction with follow-up interviews, was designed to assess participants' decision-makings, information preferences and reasoning modes. Followed a short introduction of each issue two briefs for both position statements were constructed. The briefs were written as equally as possible. The contents of the arguments did not necessarily require technical knowledge in order to comprehend the issues. A total of 180 in-service teachers were selected from 53 elementary schools across various areas by using snowball sampling. Finally, 113 teachers, including 55 science majors and 58non-science majors, completed the questionnaire and 23 of them were interviewed consequently. Analyses indicated that some differences were found between science and non-science major teachers in their information preferences and decisions on the three environmental issues. Participants based their judgments primarily on personal knowledge and values. Implications for teacher education and professional development are also discussed.
