相较于高中物理,初中物理内容浅显易懂,跟日常生活联系也比较紧密,学生在学习中感到较轻松。而进入高中以后,由于教材难度加大、学生认知能力、运用数学知识能力欠佳、学习方法上的不适应,所以学生普遍感觉高中物理难学。目前,我国初高中教师各司其职,甚至有些地区要求初高中部分开办校,很少有高中教师对初中教学有身临其境的体会。笔者经历了两轮初高中循环教学,经过思考,提出降低高中物理学习门槛的一些有效措施。一、有效掐准初、高中物理学习的焊接点建构主义理论认为学生获取知识可以跳过教师 Compared to high school physics, junior high school physics content easy to understand, with the daily life is also more closely linked, students feel more relaxed in learning. After entering high school, due to the increased difficulty of teaching materials, students’ cognitive abilities, poor ability to use mathematical knowledge, learning methods do not meet, so students generally feel that high school physics is hard to learn. At present, teachers in junior and high schools in our country perform their duties one after another, and some regions even require some senior high schools to set up their own schools. Few senior high school teachers have an immersive experience in junior high school teaching. After two rounds of high school teaching, I experienced some effective measures to reduce the threshold of high school physics study. First, effectively pinch the beginning, high school physics learning solder point constructivism theory that students can acquire knowledge can skip the teacher
