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(jī)械制圖是一門(mén)工科學(xué)生的專業(yè)技術(shù)基礎(chǔ)課，是后續(xù)課程學(xué)習(xí)、課程設(shè)計(jì)和畢業(yè)設(shè)計(jì)不可缺少的工具。在制圖教學(xué)中開(kāi)展競(jìng)賽不僅是檢查教學(xué)效果的一種有效手段，更能促進(jìn)學(xué)生自主學(xué)習(xí)。而命題對(duì)于競(jìng)賽而言又是中心環(huán)節(jié)。題目設(shè)計(jì)得過(guò)于簡(jiǎn)單，與平時(shí)的期中期末考試區(qū)別不大，調(diào)動(dòng)不了學(xué)生學(xué)習(xí)積極性；題目設(shè)計(jì)過(guò)難、過(guò)偏，又達(dá)不到以賽促學(xué)的目的。該文給出了此次競(jìng)賽試卷質(zhì)量的分析方法和分析結(jié)果，以對(duì)該競(jìng)賽作出正確地分析和評(píng)價(jià)，更有利于以后的教學(xué)改革，從而提高學(xué)生的綜合應(yīng)用能力。
