回归直线方程是统计中数据处理的常用方法,蕴涵了丰富的统计思想,是培养学生探究意识和创新能力的好素材.笔者发现,对这一内容的教学有一些共同的、不尽人意的地方,各种期刊对它的教学研究也仅停留在表面.究其原因,可能是:①教师自己的概率与统计知识贫乏,对统计思想的理解不到位;②以往高中数学课程中概率统计内容少,教师对教材陌生;③与中学概率统计教学相适应的参考资料少等等.
Regression to the linear equation is a common method of statistical data processing, contains a wealth of statistical ideas, is to develop students to explore awareness and creative ability of good material.The author found that there is some common teaching of this content, unsatisfactory place , All kinds of journals on its teaching and research also only stay on the surface.The reason may be: ① teacher’s own lack of probability and statistical knowledge, understanding of statistical thinking is not in place; ② high school mathematics curriculum in the past the probability of statistics less , Teachers unfamiliar with the teaching materials; ③ with probability and statistics teaching secondary school less reference materials and so on.
