應用資料探勘技術探究高中兼任行政教師在職進修研習課程之特徵

Exploring the Characteristics of In-Service Training Courses for High School Teachers Serving as Administrators: A Data Mining Approach

研究旨在應用教育資料探勘技術，探究高中兼任行政教師在職進修研習課程的潛在特徵與結構模式。資料取自教育部「全國教師在職進修資訊網」2024年全國高中兼任行政教師之研習紀錄，共計5，442人，研習課程逹104，390參加人次。研究採用Apriori演算法，探勘教師背景與課程屬性之間的關聯規則，利用支持度、信賴度及提升值篩選出有意義且正相關的規則，以供改進教師在職進修研習課程規劃之參考。研究發現：一、教師在職進修以「公立學校」及「40-50歲」為主力群體。二、教師高度傾向選擇「第一階基礎-瞭解熟悉」及「2小時以下」的研習課程。三、北部傾向短時數課程、中部重視公立學校進修、南部具有性別參與特徵、東部偏好日間研習，顯示研習特徵具有顯著的在地差異。

This study aims to apply Educational Data Mining (EDM) techniques to explore the potential characteristics and structural patterns of in-service training courses for high school teachers serving as administrators, utilizing large-scale training data. The research data were obtained from the Ministry of Education’s ''National In-service Teacher Education Information Network,'' comprising completed training records for the year 2024. The dataset includes 5,442 high school teachers serving as administrators, with a total of 104,390 course participation entries. The study employs the Apriori algorithm to mine association rules between teacher backgrounds and course attributes. By utilizing Support, Confidence, and Lift, meaningful and positively correlated rules were filtered to serve as a reference for improving the planning of in-service training courses for teachers.
The results of the study indicate the following:
1. Demographic Dominance: The primary group of high school teachers serving as administrators participating in in-service training consists of teachers from public schools and those aged 40 to 50.
2. Course Preferences: These teachers show a strong preference for courses categorized as ''Level 1: Basic–Understanding and Familiarity'' and short-duration courses of ''less than 2 hours.''
3. Regional Variations: Significant regional differences in training characteristics were observed: the Northern region tends toward short-duration courses; the Central region shows a prevalence of training in public schools; the Southern region exhibits distinct gender-based participation patterns; and the Eastern region prefers daytime sessions.
