陽明大學護理學院研究所之高級產兒科護理學以問題導向學習法為教學策略，以小組討論學習方式逐步培育學生。本研究目的乃以焦點團體及概念圖兩種研究方法，來測試此教學法之護理研究所第一年課程上、下學期學生之學習經驗及批判性思考能力之教學成效。於一年級期末針對兒科組四位研究生進行資料收集。焦點團體旨在調查學生的學習經驗，以錄音方式進行資料收集並以內容分析法進行分析，研究結果共粹取出七個主題，顯示學生經歷了一個建構系統思考、整合知識與實務，與批判性思考的學習經驗。此外，以學生上、下學期個案報告之概念圖評值批判性思考能力之改變。結果顯現學生於概念澄清、概念相關性、系統思維與多元思考層面均有增進。研究結果對護理專業、研究所家庭護理課程之設計，及以問題導向教學的方式提供一科學性知識之參考。

The advanced maternal-child nursing program at National Yang-Ming University is using problem-based learning and small group discussions to improve the quality of thinking among graduate students. By using focus groups and concept map assessments, the purposes of this study were to examine the effectiveness of the program in regard to their learning experience and the improvement of their critical thinking abilities. Data were collected from four students in the graduate pediatric program. The focus group interview process was tape-recorded and a content analysis was performed. The results showed seven themes and indicated that students experienced a change in systematic thinking, integrated knowledge and practice, and an enhanced critical thinking learning experience. Furthermore, a study of the changes in critical thinking using a concept map from students was performed. The results showed students' concept clarity, the relationships of concepts, systematic thinking and multiple thinking improved. The results provide a scientific foundation for using problem-based learning methods in graduate level nursing programs.
