|Abstract:||先前的研究發現，國三學生參與數學補習雖有正面的效果，但效果值並不大。由於補習是放學後一種補充性的學習活動，一項合理的假設是:開始補習的時間愈久，補習的效果也會愈好。本文使用台灣教育長期追蹤資料庫(Taiwan Education Panel Survey, TEPS) 追蹤樣本驗證此種假設是否成立。依據開始補習數學的時間， TEPS 的國中樣本可區分出國一到國三上學期都有補習者、國二開始補習者、國三開始補習者，以及國中期間從未補習者等四種類型。本文運用傾向分數配對法進行資料分析，以國中期間從未補習者做為對照組，分別探討前三種補習類型，若在不給予補習的情況下，其補習數學的平均效果為何?研究結果發現:一、數學補習的時間愈久，補習者與不補習者間，在個人特性與家庭背景等的差異處就愈多;二、從國二開始補習數學者的平均效果值最大，以滿分100 分的情況來看，其效果值約為三分。從國一開始連續補習，或者從國三開始補習，其效果值都不明顯。|
Our previous research has shown that cram schooling in 9th grade in Taiwan has a positive but fairly small effect on math performance. Since cram schooling is supplementary learning after school, it is possible that the earlier a student startsparticipating in cram schooling, the bigger the effect is. We explore this possibility by using the core panel data ofthe Taiwan Education Panel Survey (TEPS).We identify four types of students in terms of the length of their participation in math cramming during junior-high school years. We use the method of propensity score matching (PSM) to explore the average treatment effect on the treated (ATT) by comparing those who have participated in math cramming since 7th, 8th, and 9th grade separately with those who have never had math cramming during junior-high years.With different matching estimators, all results of PSM analysis indicate small or no effect of cram schooling on math performance, irrespective of how long the math cramming is. The largest ATT found is for those who have participated in math cramming since the 8th grade. The size of the effect is around 3 points if the highest math ability score is 100. For those who undertake math cramming since the 7th grade or only in the 9th grade, there are virtually no gains from cram schooling.
