【摘要】 在分析化学实验中,评价学生的实验成绩,传统的方法是用教师预先所做的几个测量数据作为标准,这样给学生的数据评分是不完全合理的。文章以学生测定水的硬度实验为例,应用Matlab软件编制程序对学生的数据进行分析,能快速、简便、直观地绘制出相应学生实验数据分布的图形,这样就能客观、公正地评价学生的实验数据。更多还原

【Abstract】 In the process of analytical chemistry experiments,the traditional method of evaluation of students’ experimental results is to use several measurement data done by teachers in advance as the standard,therefore data of students’ score is not entirely reasonable.This paper takes the student determination of hardness of water experiment as the example,analyzes the data by application of Matlab software programming for students in order to fast,simply and intuitively draw the corresponding experiment data distribution graph,therefore evaluation of students’ experimental data can be objective and fair.更多还原
