物理学中对于多因素(多变量)的问题,常常采用控制因素(变量)的方法,把多因素的问题变成多个单因素的问题。每一次只改变其中的某一个因素,而控制其余几个因素不变,从而研究被改变的这个因素对事物的影响,分别加以研究,最后再综合解决,这种方法就是控制变量法。新课程的核心理念是以学生发展为本,课程改革要培养学生的信息收集和整理的能力、发现问题和思考问题的能力、分析问题和解决问题的能力、终生学习和创新
For multi-factor (multivariable) problems in physics, control factors (variables) are often used to turn multivariate problems into one-factorial problems. Each time they only change one of the factors, and control the remaining several factors remain unchanged, in order to study the impact of this changed factor on things, respectively, to study and finally comprehensive solution, this method is to control the variable method. The core concept of the new curriculum is based on student development, curriculum reform to develop students’ ability to collect and collate information, the ability to find and think about problems, the ability to analyze and solve problems, lifelong learning and innovation
