【摘要】：上海参加了2012年的国际学生评估项目(PISA)测试,15岁的上海中学生在数学、阅读和科学素养测试中均排名第一,作业时间也是排名第一。与此同时,我国60多年来颁布的多道"减负"令收效甚微。高素养成绩是长时间的课外学习导致的吗?为了回答这一核心问题,本研究根据PISA2012上海15岁学生的数据,分析课外学习时间与数学素养成绩的关系,并探索课外学习时间的合理性和有效性。结果表明,作业时间与数学素养成绩呈现中度正相关关系,家教时间、与家人学习时间和电脑学习时间与数学素养成绩呈现低负相关关系,辅导班时间与数学素养成绩呈现低正相关关系。具体而言每周作业时间小于11小时,作业时间与数学素养成绩呈现正相关关系,大于11小时无明显相关关系。其关系满足三阶曲线方程,对方程求二阶导数,拐点为24.78,即当家庭作业时间超过每周24.78小时,学生数学素养成绩不升反降。
[Abstract]:Shanghai took part in the International Student Assessment Program (PISA) in 2012. The 15-year-old Shanghai high school student ranked first in math, reading and science literacy tests, and in homework time. At the same time, China's more than 60 years of promulgation of the "burden reduction" order has had little effect. Is high accomplishment a result of long extracurricular study? In order to answer this core question, this study analyzed the relationship between extracurricular learning time and mathematics literacy achievement, and explored the rationality and effectiveness of extracurricular learning time according to the data of 15-year-old students in PISA2012 Shanghai. The results showed that there was a moderate positive correlation between homework time and math literacy achievement, and a low negative correlation between homework time, family learning time and computer learning time, and math literacy achievement. There was a low positive correlation between the time of tutoring and the achievement of mathematics literacy. Specifically, the time of homework is less than 11 hours per week, and the time of homework is positively correlated with the achievement of mathematics literacy, but there is no obvious correlation between the time of homework and the achievement of mathematics literacy. The relation satisfies the third order curve equation, and the second derivative of the equation is obtained, the inflection point is 24.78, that is, when the homework time exceeds 24.78 hours per week, the students' mathematics accomplishment scores will not rise but decrease.
