近年來，隨著時代的變遷及社會人口結構的改變，教育改革聲浪呼聲四起，而教師因居教改成敗之關鍵，其專業發展與素質便受到前所未有的重視及關注。面對社會大眾對教師專業知能的盼望與期待，我國應在師資培育職前教育階段提前儲備職前教師的專業知能，以迎接未來教育職場的挑戰。問題本位學習(Problem-Based Learning, PBL)強調理論與實務的連結、問題解決技能、同儕合作、自我導向學習及專業知識的建構，其特性非常適合應用於我國目前對職前教師專業發展的期待。本文首先論及我國師資培育職前教師專業發展的危機與挑戰；其次，探討PBL之意涵與特性，提出PBL於師資培育職前教育應用之理論基礎；接著，以PBL之原理與應用爲基礎，試圖提出PBL於師資培育職前教育之實施歷程及功能與限制，以供我國應用之參考；之後，探究國外PBL於師資培育職前教育之應用，以做爲我國之借鏡；最後，透過文獻的探討及國外的經驗，提出PBL於師資培育職前教育應用之展望做爲結語。冀望透過本文之探究，能引起國內師資培育機構、師資培育者與相關教育單位對師資培育職前教育之重視，並根據我國師資培育職前教育的背景脈絡與時代需求，將PBL教學模式應用於師資培育職前教育之中，進而建全職前教育的課程規劃與品質，符應教育改革對教師專業發展的期待。
