本研究以一系列的合作行動研究,使生手教師(個案教師)能發展其STS(Science/Technology/Society)教師專業能力,著者作為個案教師經由下列四階段發展STS教師專業能力:階段一、參與STS教師研習活動;階段二、經由參加"溫室效應"STS錨式活動發展;階段三、在鷹架學習情境中開發及帶動STS活動發展教師專業能力;階段四、帶動錨式及鷹架式共創活動發展教師專業能力。經由這四個階段,著者以教學者、學習者和研究者的角色,使用教學歷程檔案為學習及評量工具建構STS教師專業能力。本研究結果顯示透過合作行動研究,以四階段的教師專業能力發展方案及建立教學歷程檔案之附加價值法能培育STS教師專業能力。建立教學歷程檔案之附加價值法促使教師自省、自評、自律、自信及願意為自己的學習負責。研究結果發現經過四階段培育之教師能發展學習者之STS素養,進而激發以價值為中心的創造力。因此著者建議應鼓勵教師們經由合作行動研究培育STS教師專業能力。
This thesis is about a series of collaborative action researches for an STS teacher's professional development. The author as the case teacher went through the following four stages. Stage 1: An STS teacher workshop. Stage 2: STS learning under anchored "greenhourse effect" STS activities. Stage 3: Under scaffolded instruction, designing and carrying out "acid rain" STS activities. Stage 4: Under less scaffolded instruction, carrying out the expanded "acid rain" activities which encourage learners' cooperative creation with STS exploratory experiment. Throughout the four stages, the author as learner/teacher/researcher, used portfolio as learning and assessment tools to construct pedagogical content knowledge. The results of this study showed that, through collaborative action researches, the four-stage teacher development program and value-added portfolio building method were able to promote STS teacher's professional capabilities. This value-added method in building portfolio motivated the teacher's self-reflection, self-evaluation and self-regulation, self-confidence and willingness to take charge of his own learning. The teacher in turn was able to promote learner's STS literacy, especially value-centered creativity. The author suggests that teachers should be encourage to promote their professional capabilities through collaborative action researches.
