化学实验数据处理是学生必备的实验能力,也是化学计算考查的一个重要载体.然而笔者在教学中发现,学生在这方面发生的错误非常多.分析其错误原因,主要有以下几个方面.一、反应原理不清楚,找不准各物质间的转换关系随着高中新课程改革的不断深入,化学教学与生产、生活的联系越来越紧密,化学实验的考查也越来越注重实用性.在题中往往会设置与生产、生活有关的情景,反应原理也常常会 Chemistry experimental data processing is an essential experimental ability of students, but also an important carrier of chemical calculation test.However, I found in teaching, students in this area are many errors occurred.Analysis of the causes of errors, mainly in the following aspects. First, the reaction principle is not clear, find out the relationship between the conversion of the material With the deepening of the reform of high school new curriculum, chemistry teaching and production, life more and more close, more and more emphasis on practical experiments in chemical experiments In the title often set production and life-related scenarios, the reaction principle is also often
