传统的教学偏向于平均数的算术意义,忽视平均数的统计学意义。通过选取梁绍君教授平均数理解“四水平”中的前三个水平,即以平均数的“本义性理解水平”“特异性理解水平”“加权性理解水平”为维度,论述了在小学数学教学中如何让学生理解平均数的统计意义。
Traditional teaching prefers the arithmetic mean of the mean, ignoring the statistical significance of the mean. By selecting the average number of Professor Liang Shaojun understanding “four levels ” in the first three levels, that is, the average “original meaning of understanding level ” “level of specificity of understanding ” “weighted level of understanding ” Dimensions, discusses the statistical significance of how to make students understand the average in elementary mathematics teaching.
