Shizi Peiyu Yu Jiaoshi Zhuanye Fazhan Qikan, 2010 本文探討四位師資生在教學實習課程集中實習期間的教學省思。藉由分析省思札記的省思主題與省思層次，以瞭解師資生的學習以及省思品質。研究結果顯示：（一）省思主題涵蓋五個範圍：教學方法與教學過程、教學評鑑、輔導老師行為與理念、自我知覺、參考理論與文獻。由各主題的條目數量多寡透露：師資生最重視各科教學方法與教學過程，而甚少聯繫正式知識於教學實務。（二）省思層次出現「描述」、「描述省思」、與「對話省思」。其中，不具備省思特質的「描述」條目，稍多於其他兩項的總和。就省思品質而言，師資生實踐四種省思類型，缺少批判省思 ...
