고등학생 학업성취에 대한 학교효과와 과외효과의 비교연구

다국어 초록 (Multilingual Abstract)

This study compares the effects of private tutoring to the effects of in-school
education on the academic achievement of high school students in Korea. The gain
in popularity of private tutoring and out-of-school private lessons among Korean
students is causing social and financial problems both for individual families and
the country as a whole. Another problem is that as quality of public education in
schools declines, students and parents have relied heavily on out-of-school
private lessons for academic achievement. Thus, it is time to empirically determine
the effects of both sectors of education on our students achievement, and evaluate
them objectively, so that we can clarify our beliefs and concepts of their
respective values.
This study is based on the quantitative analysis of survey data collected by
researchers using both a questionnaire administered to a nation-wide sample of
918 students from 30 general high schools, and a preliminary version of the
Korean Scholastic Aptitude Test prepared by a major private testing institute.
Multiple regression analysis was employed to estimate the effects of both sectors
of education on performance, with appropriate controls of predetermining variables
(e.g. sex, family background (parents education, income and cultural capital),
personal characteristics (IQ, educational aspirations), and geographical region).
The resulting data found that taking out-of-school private lessons did not
appear to affect mathematics performance between the first and second
achievement tests, while in-school education did have an affected on students
mathematics performance.
