实验考核对学生成绩分布影响

为了提高非预防医学专业学生的预防医学方面的基本技能、操作能力和综合水平，更为真实反映学生素质和教学质量，按照使用的教材选择96、97级学生做实验组进行实验考核，95、98级学生做对照组。结果为：96、97级学生总平均成绩符合教学评估要求，呈正态分布，成绩分布更为合理；而95、98级学生总平均成绩呈明显偏态分布。

The Influence of Experiment Examination to Achievement Distribution

In order to strengthen high opinion to the experiment on preventive medicine of the non-preventive medicine specialty student, to improve the operation ability and synthetically level of student more truly reflecting the results distribution, we choose the students of 96 and 97 grades as the experiment group , and the students of 95 and 98 grades as the contrast group according to the use of the teaching material to do experiment examination . The result is: the average achievement of the students of 96 and 97 grades (experiment group) fits the teaching appraisal requirement, presenting normal distribution; but the average achievement of the students of 95 and 98 grades (contrast group) presents skewed distribution. The achievement distribution of the experiment group is more reasonably.
