请参考以下给出试卷评价的数据,参考教科书,说说你觉得本次出题哪里可以加强?有哪些优缺点?(提示,注意看几个数值,比如难度与区分度的关系等)
(小活动)你觉得这次试卷设置怎么样?
The difficulty of the test questions is relativity small, and the students generally reach the pass rate but the excellent performance is not obvius,and there are obviously a few questions with a dividing line. The difficult of the topic is moderate and it is suistable with different learning situations. the percentangen of the application certificates and increase the ability of enviromental analysis it also can be made when the propotions of two rounds is out, the number of questions is too small , it should not be too many , but it can increase the activity of thr model appropriately the projects are clearly differentiated and widely used it can be considered as a good product to add to the characteristics of nursing education. Thank you so much have a good day
1.从难度上看,本次试卷的难度基本在0.75左右。一般认为,试题的难度指数在0.3-0.7之间比较合适,整份试卷的平均难度最好在0.5左右,高于0.7和低于0.3的试题不能太多。虽然本次还是有一定的检测学习成果作用,但是难度偏高会导致所反映出来的学生学业水平有所偏差。
2.区分度是区分应试者能力水平高低的指标。试题区分度高,可以拉开不同水平应试者分数的距离,使高水平者得高分,低水平者得低分,而区分度低则反映不出不同应试者的水平差异。试题的区分度与试题的难度直接相关,通常来说,中等难度的试题区分度较大。另外,试题的区分度也与应试者的水平密切相关,试题难度只有等于或略低于应试者的实际能力,其区分性能才能充分显现出来。一般认为,区分度指数高于0.3,试题便可以被接受。因此,本次出题在区分度方面可以加强,从全体同学试卷评分上看,所体现出来的成绩都很集中,高分段人数很少,能体现出来的学生素质不明显,数据反映出来的是同学们的水平都很平均,但是考核应该是检测每一个人的技能理论水平如何,从而做到真正的培养人才。而此次的优点有全面覆盖本课程的知识点,让学生得到更全面的测验体会。
