从生理角度看,高中学生正处在青年初期。随着第二特征的日益明显,学生的心理也发生了微妙的变化。这种心理变化是正常的,也是不可忽视的,只有掌握学生这种心理变化的规律才能因势利导,因材施教,取得较好的教学效果。我在教学中体会到,与初中生相比,多数高中生表现为上课不爱发言,讨论气氛不浓,与老师逐渐产生隔阂感,即使同学之间朝夕相处,也不大愿意公开自己的心事。心理学上把这种青年初期最显著的心理特征称为闭锁性。闭锁性给物理教学带来很大障碍。许多教师在课堂上启而不发,于是只好仍由自己讲,实际上有些问题老师讲得越多,学生学得越差。应当看到,高中生在产生闭锁性心理的同时,还产生了渴望老师能理解他们快要长大成人了,理解他们有一定的分析、思考问题的能力。他们不喜欢那种初中 From a physiological point of view, high school students are in the early stages of youth. As the second characteristic becomes more apparent, the student’s psychology has also undergone subtle changes. This kind of psychological change is normal and can not be ignored. Only by mastering the laws of students’ psychological changes can we make use of the situation, make decisions in accordance with their aptitude, and achieve better teaching results. In my teaching experience, compared with junior high school students, most high school students do not like to speak in class. The atmosphere of discussion is not strong, and there is a sense of estrangement from the teacher. Even if the students are living together day and night, they are not willing to open their minds. Psychology calls this most prominent psychological feature of the youth as locking. Locking is a major obstacle to physics teaching. Many teachers did not start in the classroom, so they had to talk about themselves. In fact, the more questions some teachers have, the worse they learn. It should be noted that while high school students have a closed mind, they also have the ability to desire teachers to understand that they are about to grow up and understand that they have a certain degree of analysis and thinking. They don’t like that kind of junior high school
