本研究旨在探討臺中市國民中學導師實施差異化教學與班級經營效能之現況、導師不同背景變項下兩者知覺差異情形、實施差異化教學與班級經營效能之間的相關性、實施差異化教學對班級經營效能的預測力等。本研究以臺中市公立國民中學導師為研究對象，採用問卷調查法蒐集研究資料，並運用描述性統計、獨立樣本t 檢定、單因子變異數分析、Pearson 積差相關、逐步多元迴歸等統計方法進行資料分析。本研究結果發現導師對於實施差異化教學和班級經營效能的知覺均屬於中高程度，而不同任教科目的導師所知覺的實施差異化教學有顯著差異，不同擔任導師年資和學校地區的導師所知覺的班級經營效能亦有顯著差異。就相關性部分，實施差異化教學與班級經營效能具備顯著正相關，並實施差異化教學對班級經營效能具備顯著的預測力。
