摘要
通过设计教学试验采集数据,运用计算与比较样本方差、样本均值等方法研究了寝室风气、课后作业和课堂练习等因素对学生高等数学成绩的影响,并提出了相应的改进措施以取得良好的教学效果.
The impacts of the bedroom atmosphere,homework and class exercises on advanced mathematics achievement were studied by designing teaching experiments,collecting relevant data and computing sample variance and sample mean value.Corresponding improvement measures were proposed to improve the teaching effect of advanced mathematics.
