近几年的高考物理实验,在立足教本实验的前提下,求新求变,让学生防不胜防。笔者认为要想让学生从容应对高考物理实验,应着重实验原理的理解,同时引入开放式教学的理念,在完成基本实验的前提下,消除实验缺憾、突破实验难点,做到一个实验多种方案,培养学生灵活运用物理知识的能力。下面我就《探究功与速度变化间的关系》这一实验为例,说说我的观点。
In recent years, college entrance examination physics experiments, based on the textbook experiment under the premise of innovation and change, so that students are hard to guard against. I believe that in order to make students calmly deal with college entrance examination physics experiments should focus on the understanding of experimental principles, while introducing the concept of open teaching, the completion of basic experiments under the premise of eliminating experimental shortcomings, breaking the experimental difficulties, to achieve an experimental program , Develop students’ ability to use physical knowledge flexibly. Below I will “explore the relationship between power and speed changes,” the experiment as an example, to talk about my point of view.
