本研究旨在探討國民小學教師知識分享與專業成長之關係。本研究採用問卷調查法，以臺中市豐原區國民小學教師為研究對象進行抽樣，有效樣本計有182份。以「國民小學教師知識分享與專業成長之調查問卷」為研究工具。所蒐集之資料以描述統計、t考驗、單因子變異數分析、典型相關及多元回歸進行分析。獲致下列結論：（1）國民小學教師知識分享之現況，屬於中高程度。其中「分享學習機會」層面最佳。（2）國民小學教師專業成長之現況，屬於中高程度。其中「班級經營」層面最佳。（3）不同背景變項在知識分享之差異分析中，不同現任職務之國小教師在知識分享方面達到顯著差異存在。（4）不同背景變項在教師專業成長之差異分析中，不同性別、教學年資、現任職務及最高學歷之國小教師專業成長方面均無顯著差異存在。（5）就國小教師知識分享與教師專業成長的典型相關分析可以發現，教師知識分享與教師專業成長達顯著相關。(6) 就國小教師知識分享與教師專業成長的預測分析可以發現，教師知識分享項目中的「分享個人內在知識」與「促進他人學習」對教師專業成長具有顯著預測作用。根據研究結果，研究者提出若干建議，提供教育行政機關、國民小學及未來研究之參考。
