物理是一门实验科学,考查学生的实验技能是物理考试命题的一项重要内容。初三物理第三章中“测定物质的比热”这一学生实验,以其涉及知识广、使用器材多、操作要求高、测量数据难、计算结果繁和要求误差分析等诸多特点,颇得各级各类考试命题者的青睐。因此,熟悉有关此实验的各种命题形式及特点十分必要。通过对各地历年来中考及其它考试试题的分析可以看出,此实验常从以下几个方面进行考查。
Physics is an experimental science. Examining students’ experimental skills is an important part of the physics examination proposition. The “Specific Heat of Determining Substances” student experiment in the third chapter of Physics in the third year of the physics area has been widely used due to its wide range of knowledge, use of equipment, high operating requirements, difficult measurement data, complicated calculation results, and requirement error analysis. All types of exam propositions of all ages. Therefore, it is necessary to be familiar with the various propositions and characteristics of this experiment. Through the analysis of the examinations and other examinations over the years, it can be seen that this experiment is often examined from the following aspects.
