本研究的主要目的在探討批判思考教學師資培訓的「最適合(best-fit)」模式,從而提議一有效的批判思考教學師資培訓之參考模式。本研究的參與者為75位職前教師;測量工具為一個電腦模擬教學課程和二份李克特式量表;分析方法則包括描述統計、Hotelling’s T2、以及Structural Equation Modeling。本研究發現(1)一個有效的批判思考教學師資培訓課程至少涉及四個因素:參訓投入程度以及批判思考教學專業知識、個人教學效能與教學行為;(2)職前教師的「參訓投入程度」對其批判思考教學的專業知識及教學行為之改變有直接且正面的效果,對其個人教學效能的改變則有正面但間接的效果;(3)在批判思考教學的過程中,職前教師批判思考個人教學效能的改變為其教學專業知識與教學行為的改變之中介變項。 The major purposes of this study were to find out the “best-fit” model for teacher-training in critical-thinking instruction and, accordingly, suggest and effective training model for critical-thinking instruction. Seventy-five preservice teachers participated in this study. The employed instruments were a computer-simulation program and two Likert-type questionnaires. The applied analyses included descriptive analysis, Hotelling’s T2, and Structural Equations Modeling (SEM). The major findings revealed that (a) an effective program for teacher training in critical-thinking instruction involves at least four factors: training-involvement level, professional knowledge, personal teaching efficacy, and teaching behavior related to critical-thinking; (b) the preservice teachers’ “training-involvement level” directly influenced their improvement in professional knowledge and teaching behavior, but indirectly enhanced their personal teaching efficacy for critical thinking; (c) the preservice teachers’ change in personal teaching efficacy was a mediator of their change in professional knowledge and teaching behavior during critical-thinking instruction.
