大学生实验课堂成绩评定系统的设计

Design of the Grade Evaluating System for Experiment in University LAB

针对由教师对大学生的实验课堂成绩做主观评定存在的问题,设计一个进行客观成绩评定的系统。每个实验室设置一台计算机,并在各实验台安装键盘及显示装置与计算机相连,由学生输入个人信息和实验结果,成绩计算软件根据学生的到课时间、操作情况及实验数据等因素对当堂成绩进行评定。该系统的应用既可使实验指导教师免于评定学生的课堂成绩,而全心致力于实验的指导工作,又能增加成绩评定的客观性,有利于调动学生学习的积极性。给出了系统结构及部分程序流程图。

The objective grade evaluating system is designed for some problems that teachers subjective 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,then,the laboratory computer will calculate their scords by the factors such as experimental time,earnestness and accuracy about the experiment.It will save time of teachers and arouseing students initiative because of the grade evaluate is objective.The composition and flow process chart of the system is provided.
