應用決策樹分析視導人員專業能力與學校視導績效之關係

Applying Decision Trees to Investigate the Relationship Between Supervisor Professionalism and the Efficacy of School Supervision

本研究旨在分析我國中小學教育視導人員專業能力與其視導績效之關係。本研究以問卷調查方式進行，調查對象為臺灣地區二十二縣市公立國中小校長，回收樣本總計1,261份。本研究所探究視導人員專業能力內容包含：工作職務與專業素養。視導績效探討內容包含：視導責任、校務協助、行政管理與教學視導。本研究主要採決策樹（Classification and Regression Trees, CART）演算法進行分析。研究發現，影響視導績效最主要的專業能力為視導人員公共關係營造與資源整合之能力。此外，透過分類路徑亦發現，學校視導績效與視導人員教學視導能力有正向關係。

This study analyzed the performance of school supervision at primary and secondary levels and the factors influencing this performance. Questionnaires were used to collect data from primary and secondary school principals in 22 cities and counties in Taiwan; 1,261 valid questionnaires were returned for data analysis. In this study, professional competence refers to a person’s aptitude for carrying out employment-related tasks. Performance of supervision refers to the execution of supervision responsibilities, school assistance, administrative management, and instructional supervision. The study utilized the classification and regression tree algorithm to analyze the factors influencing local education supervision. The main factor was determined to be a supervisor’s professional competence in public relationship establishment and resource integration. In addition, the study found that there is a positive correlation between performance of school supervision and a supervisor’s capacity for instructional supervision.
