Abstract: The difficulty, distinction, coverage and reliability of examination papers were analyzed in this paper. The results show that the difficulty coefficient was 0.598, the distinction coefficient was 0.504, the coverage coefficient was 0.762, the paper reliabity was 0.667. The difficulty of the test was more difficult, the distinction was good and thus test was reliable. This paper suggests some recommendations how to raise the level of preparing test papers and adjust arrangement of the teaching in the future.

機械制圖是一門工科學生的專業(yè)技術(shù)基礎課,是后續(xù)課程學習、課程設計和畢業(yè)設計不可缺少的工具。在制圖教學中開展競賽不僅是檢查教學效果的一種有效手段,更能促進學生自主學習。而命題對于競賽而言又是中心環(huán)節(jié)。題目設計得過于簡單,與平時的期中期末考試區(qū)別不大,調(diào)動不了學生學習積極性;題目設計過難、過偏,又達不到以賽促學的目的。該文給出了此次競賽試卷質(zhì)量的分析方法和分析結(jié)果,以對該競賽作出正確地分析和評價,更有利于以后的教學改革,從而提高學生的綜合應用能力。
