摘   要
Internet/Intranet技術(shù)的發(fā)展和普及，計(jì)算機(jī)化考試在許多方面將逐步取代傳統(tǒng)的基于紙筆的考試。這種安全可靠、自動(dòng)化及大規(guī)模的無紙化考試系統(tǒng)可以準(zhǔn)確地評(píng)估被考核者的能力和水平，提高考試效率。探討和研究基于計(jì)算機(jī)網(wǎng)絡(luò)的考試系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)，具有特別現(xiàn)實(shí)的意義和推廣價(jià)值。
基于web的答題評(píng)卷系統(tǒng)為考試無紙化提供了一套完整的解決方案，提供了相當(dāng)完善的功能，包括用自動(dòng)/人工閱卷、成績統(tǒng)計(jì)、成績查詢、信息發(fā)布、單元測試、綜合模擬和在線考試等功能。系統(tǒng)克服了C/S結(jié)構(gòu)的不足，采用了基于B/S結(jié)構(gòu)的分布式Web應(yīng)用程序結(jié)構(gòu)，開發(fā)過程中主要應(yīng)用了ASP.NET，SQL SEVER等關(guān)鍵技術(shù)。
系統(tǒng)突破了傳統(tǒng)的計(jì)算機(jī)考試以理論客觀題為主要題型的考核方式，題型完整，實(shí)現(xiàn)了基于Internet的簡答題，畫圖板等計(jì)算機(jī)操作題的考核。采用開放式題庫，每道題目均由“題型”、“難度系數(shù)”、“知識(shí)點(diǎn)”等參數(shù)組成，從而保證試卷內(nèi)容的多樣性和多學(xué)科通用性。
網(wǎng)絡(luò)考試系統(tǒng)是未來考試發(fā)展方向的必然趨勢，可以有效地提高考試系統(tǒng)的規(guī)范化及大規(guī)模考試的效率，并將廣泛應(yīng)用于各種考試中。

Abstract
With the development and popularization of Internet/Intranet, conventional examination based on paper and pencil will be substituted for computerized one. The reliable and automation and a large of scale paperless examination system may precise eva luation for the examiners' capabilities, and may be more effective. The reach on Internet-based examination is becoming practically meaningful and will be used widel.
This system provides a complete solution for paperless test. It provides functions including automatic or handmade eva luation test papers, score statistics, score query, information publication, unit test, comprehensive simulation, test on line, and so on. This system has overcome the disadvantage of C/S structure and is based on the B/S three tiers architecture of Web application, the main technology used in the system includes ASP.NET technology.
The system has broken through the traditional way of computer-examination, which is mainly for objective questions, and realizes automatic management for a lot of operating types of questions on the Internet. For example, Word, drawing board, etc. Open test bank is used, every questions composed of such parameters as test-type, test-difficulty, test-content, etc. The test bank will make the system used widely.
The system can enhance formalization and efficiency of alarge scale Internet-based examination, and it will be extensively used in all kinds of examinations.

 Key words：Examination without paper，drawing board，online testing，online checking
