Difficulty Analysis and Quality Evaluation of Mechanical Drawing Test Questions in Adult Higher Education

针对成教机械制图课程考试编制的主观性试题和客观性试题各自适合采用的量化分析指标,结合实例作了难度、区分度简要计算及分析,确定机械制图分类题采用主观性试题的难度系数、区分度系数公式计算。结合实例分析了选择题的干扰项,明确了质量评价方法。探讨成教机械制图课程学业水平考试,试题的难度要适合考查成教学生机械制图的水平与目标,试题的区分度要求不应太高。

According to the quantitative analysis indexes suitable for subjective and objective examination questions in adult mechanical drawing course examination, the difficulty and discrimination are briefly calculated and analyzed with examples, and the difficulty coefficient and discrimination coefficient formula of subjective examination questions are determined for mechanical drawing classification questions. The interference items of multiple choice questions are analyzed with examples, and the quality evaluation method is defined. In order to discuss the academic level examination of adult mechanical drawing course, the difficulty of the examination questions should be suitable for examining the level and goal of adult mechanical drawing, and the degree of differentiation of the examination questions should not be too high.
