大学生实验成绩自动评定系统的设计

Design of the Grade Evaluating System about Performance Test for Experiment

针对由教师对学生成绩进行主观评定所引起的系列问题,设计一个实验成绩自动评定系统,实行对大学生实验成绩的自动生成.在现有实验室操作台安装按键及显示装置,由实验室主机控制,学生将个人的实验结果传给主机,相应的成绩计算软件结合学生的具体实验情况做出成绩评定结果.该系统的使用既能增加成绩评定的客观性,又可使实验教师免于评定学生的成绩,对于教师工作强度的减轻,学生学习积极性的调动都有积极作用.设计出了系统的结构和成绩计算方法,给出了部分程序流程图及仿真结果.

The objective grade evaluating system is designed for some problems that teachers subjec- tive judgement about the college students＇ experiment scords. Computers are located in every LAB, every experiment table is connected with the laboratory computer. When the students input their personal information and their experimental findings, the laboratory computer will calculate their scords by the factors such as earnestness and accuracy about the experiment performance test. It will save time of teachers and arouseing students initiative because of the grade evaluate is objective. The composition, flow process chart and simulation waves of the system is provided.
