摘要
在分析化学课程期末考试中首次采取半开半闭的考试方式。对考试试卷进行分析,学生成绩呈正态分布,平均成绩为(68.07±12.00)分,全卷难度为0.68,区分度为0.51。该试卷试题难度适中,区分度优秀,能够全面评价学生对课程的掌握程度。这种半开半闭考试方式对学生学习成绩的评定更客观、更公平、更合理,应继续试行并逐步完善。
The test way of half-open book and half-close book was used in the final examination of analytical chemistry course at the first time. We selected all test papers of students and analyzed them. The students＇ scores were normally distributed, with the mean score being 68.07±12.00, the degree of difficulty of the test paper being 0.68, and discrimination being 0.51. The test paper could make an assessment of students＇ command of the course, with moderate difficulty and reasonable sore distribution. This test way is even more objective, fair and reasonable in grading students＇ papers. We should try to take this test way again in future examinations, then improve and perfect it.
