传统的教学课堂,教师在讲解新知识时缺乏一个过渡环节,没有让学生的大脑进行预热就开始讲解,使得很多学生都无法进入最佳的学习状态。有效的课前导入,可以激发学生学习的兴趣和探究欲望,能为接下来的教学带来极大的帮助。广大高中政治教师应该提高对导入环节的重视,并且还要不断地完善导入的方法,以提高教学效率。本 In traditional teaching classrooms, teachers lack a transitional link in explaining new knowledge and begin to explain the student’s brain without preheating, leaving many students unable to enter the best learning state. Effective pre-class introduction, can stimulate students interest in learning and explore the desire, can bring great help for the next teaching. The majority of high school political teachers should increase the importance of the introduction of links, but also continue to improve the introduction of methods to improve teaching efficiency. this
