Abstract
In the normal teaching course, the effect of teaching and learning is evaluated by the examination. After the examination, the teachers will grade the examination paper and give the analysis report of the result. The traditional grading process is laborious and inefficient. The paper proposes and develops a grading system based on network, which can grade the score according to different kind of questions. For the selective questions, the system scans the paper, grades the score automatically and stores the results into the grade database. For the descriptive questions, the system allows teachers estimate the paper in the network environment by the aid of the management system after an electronic paper is made by scanning the paper in high speed. In order to verify the efficiency of the system, 20 teachers used the system to grade the examination paper, and eval-uated the system in 9 aspects. The statistic and analysis of the evaluation proves that the system is efficient and convenient.
