教育评价选用的测量方法及其计算公式的精确程度,直接影响评价的结果。现就一些常见的弊病,提出改正意见。(一) 直接量化法计算公式的一般与特殊关系的处理问题直接量化法的计算公式是: S_(?)=(ω_(max)-ω_(min))(X_(?)-X_(min))/(X_(max)-X_(min))+ω_(min)。(1) ω_(max):本组权重分的最大值; ω_(min):本组权重分的最小值; X_(max):本组中所测或所规定的最大值; X_(min):所组中所测或所规定的最小值; The accuracy of the measurement method and its calculation formula used in education evaluation directly affects the evaluation results. Now some common ills, put forward corrections. (A) the direct quantification method to calculate the formula of the general and the relationship between the special treatment of the problem The direct quantification method is calculated as follows: S _ (?) = (Ω_ (max) -ω_ (min)) (X _ (?) - X_ (min) ) / (X_ (max) - X_ (min)) + ω_ (min). (1) ω_ (max): the maximum value of this group of weights; ω_ (min): the minimum value of this group of weights; X_max: the maximum measured or specified in this group; X_ (min) : The minimum measured or specified in the group;
