本研究目的在於分析與比較專精教師與生手教師,進行論證教學的品質、特色與異同。研究對象爲技術學院的2位教師與五專部護理系學生213位,教學課程爲「生活科技」,並在此課程中融入爭議性科技議題的論證活動。資料蒐集關注於師生的對話論證內容。資料分析時,本研究發展「對話論證表徵」分析舉證支持立場、反駁與質疑,與化解反駁等三面向的論證內涵與品質。研究發現生手教師班級的論證教學多基於舉證支持立場,師生對話論證的內容與品質較不豐富;專精教師班級的對話論證內涵亦多基於舉證支持立場,而教師重視理性、和諧的對話氣氛,更能引導學生學習反駁與質疑、化解反駁的對話論證,以及表現高品質的論證內容。
The purpose of this study was to analyze the features, progress and quality of students' argumentation in socio-scientific issue taught by an inexperienced teacher and an experienced teacher. We developed a representation as an analytical tool for tracking the progress and quality of students' argumentation. We found Chinese students tend to be unwilling to become involved in any kind of verbal exchange which has the potential for conflict (i.e. argumentation). The primary reason for such hesitancy is fear of becoming emotionally upset. When teaching students the objective process of claim/support within the context of an argumentation class, the teacher who had no past experience teaching argumentation was less effective than the experienced teacher in helping students to view such a verbal exchange objectively without involving their emotions. The experienced teacher tended to be more sensitive than the inexperienced teacher to students' shift from objective involvement to emotional involvement.
