新任教師階段乃是決定一位教師日後是否能順利專業發展的關鍵期，尤其是新任教師在專業上的教與學經驗，更會強而有力的反映在教師生涯態度及專業行為上。筆者基於對高職新任教師專業發展的關懷，乃透過文獻分析、合作自傳法、晤談法與內容分析法等，藉由新任教師專業實踐理論的建構與發展作為媒介，針對七位公私立高級職業學校的新任教師，進行為期十個月的研究，期能更實質的協助高職新任教師進行更有效的專業發展。本研究結果所獲得的重要結論，包括：新任教師專業實踐理論的建構確具有提升個人專業知覺，引導新任教師專業實踐與未來發展方向的價值；新任教師專業實踐理論發展大多與個人的直接經驗有關，且具有高度生活史的特性；新任教師的專業發展過程顯得相當孤立與具個人主義色彩等六項。
