在中学物理的学习中,不少同学感到困难,或者说开始觉得还比较轻松,经过一段时间后就越来越难了。对初中和高中两个学段的教学内容进行研究发现,中学物理学科体系存在若干个台阶。认识到这些台阶的存在,预设这些台阶教学衔接的方法,是大面积提高中学物理教学质量的关键。一、从游戏活动到实验探究学生在小学学习“科学”时,已经经历了不少科学活动。在科学活动中注重的是趣味性,也就是说学生在学习物理之前曾经历过若干次精彩有趣的科学活动,这些活动与物理实 In secondary school physics learning, many students feel difficult, or start to feel more relaxed, after a period of time it becomes harder and harder. A study of the teaching content of junior and senior middle schools shows that there are several steps in the system of middle school physics. Recognizing the existence of these steps and the method of presetting the connection of these steps are the key to improving the quality of physics teaching in secondary schools on a large scale. First, from the game activities to explore the experiment Students in primary study “science ”, has experienced a lot of scientific activities. It is fun to focus on scientific activity, which means that students have experienced several wonderful and interesting scientific activities before studying physics, which are related to physical reality
