试题的设计、修改和确定必须考虑试题本身及其在试卷中的位置等多种因素。特别是在大规模的考试中,当试卷的框架(如对每道题的题型、知识点、能力要求、分值、难度和区分度等)基本设定时,命题就受到了许多制约,困难程度也就显著提高,并非所有通常所说的“好题”都可以放进去。2004年高考(上海)第15题按照预定的总体框架设计为:选择题;北洋军阀统治;运用已有知识的阅读理解能力;2分;难度0.70左右;区分度在0.30
The design, modification and determination of test questions must take into account various factors such as the test questions themselves and their position in the test paper. Especially in large-scale examinations, propositions are subject to many constraints when the framework of the test paper (such as the question type, knowledge point, ability requirements, scores, difficulty, and differentiation, etc. of each question) is basically set. The degree of difficulty is also significantly increased. Not all of the commonly used “good things” can be added. The 15th problem of the 2004 college entrance examination (Shanghai) was designed in accordance with the overall framework of the plan: multiple choice questions; Northern Warlord rule; ability to use existing knowledge in reading comprehension; 2 points; difficulty around 0.70; discriminance at 0.30
