实验数据的分析和处理是一项很重要的实验技能,因此加强教师在实验数据处理中的指导作用,是提高学生实验能力的重要途径。所谓教师的指导并不是简单的计算示范,而应着重指导学生把握正确的数据处理方法,养成良好的思维习惯。我们认为,在实验数据处理中教师主要进行如下两方面的指导: 一、理清数据处理中的知识结构数据处理的过程,实质上是从实验数据并依据一定的已知物理规律,去探索或验证物理规律的过程,而这一过程是严格按实验本身的知识结构展开的。例如:“研究匀变速直线运动的规律”的学生实验,梗
The analysis and processing of experimental data is an important experimental skill. Therefore, strengthening teachers 'guiding role in experimental data processing is an important way to improve students' experimental abilities. The so-called teacher's guidance is not a simple calculation model, but should focus on guiding students to grasp the correct data processing methods to develop good thinking habits. In our opinion, teachers mainly conduct the following two aspects of instruction in the experimental data processing: I. Clearing up the knowledge structure in data processing The data processing process is essentially based on experimental data and according to certain known physical laws to explore or Verify the physical laws of the process, and this process is strictly in accordance with the experimental knowledge of the structure itself. For example: “study the law of uniform speed linear motion” student experiments, stems
