摘要
为提高教师工作效率和课程教学质量,东华大学结合日渐完善的图像处理技术以及网络手段,利用基于扫描识别技术开发了网上电子阅卷系统,实现了一套适合高校教学考试的电子阅卷系统,并给出微积分考试电子阅卷实例。该系统包括试卷扫描、网上阅卷、统计分析等模块。通过将纸质版试卷扫描进电脑中,获取试卷正反面图像。主观题部分,由教师根据任务分配获取相应题目图像后进行网上评阅打分,最终汇总获得总成绩,并分析统计出各题目准确率,难易程度等信息,实现阅卷信息化。随着微积分教学月考制度推行和电子阅卷系统使用,网上阅卷顺应了教学的信息化管理,实现教学工作规范化,考核管理科学化、现代化。
In order to improve teachers＇ work efficiency and teaching quality in the context of maturing image processing technology and various Internet methods,an online marking system,suitable for university-level teaching and testing,is developed and exemplified by calculus at Donghua University,based on scanning and recognition technology. The system is composed of modules such as test paper scanning,online marking,and statistical analysis. Both sides of test papers are scanned and the consequent images are stored digitally. The objective parts of the papers are graded automatically by the computer while the images of the subjective parts are assigned to and marked by teachers online. All the results are collected electronically into the total grades and analyzed in terms of accuracy rate and difficulty of each part. The monthly tests of calculus shows that the online marking system conforms to the growing trend of digitalization,normalization and modernization of education and its management and assessment.
