学生的物理化学实验报告中有许多数据、图表和繁杂的计算,教师批改工作量很大。对于一些用作图法求得数据的实验报告,还要看学生所作曲线是否正确,很费时间。尤其是难以用一种统一的标准给每份报告评分。若能用一种统一的评价标准,不仅学生满意,而且能衡量不同方法的实验结果的好坏,有利于各学校间的交流和改进实验方法。我们用价格低廉的可编程序计算器CASIO FX-702P自编程序来评价学生的物理化学实验结果,既减
There are many data, charts and complicated calculations in the students ’physicochemical experiment report, and teachers’ workload is heavy. For some experimental data used to calculate the data, but also depends on the curve made by the students is correct, it takes time. In particular, it is difficult to rate each report with a uniform standard. If we can use a unified evaluation criteria, not only the students are satisfied, but also the results of different methods can be measured in good or bad, is conducive to the exchange between schools and improve the experimental method. We use a low-cost programmable calculator CASIO FX-702P self-programming to assess the results of the students physicochemical experiments, both reduced
