本文阐述的图示法是把学生所学知识的内在联系,用直观、简明,逻辑的方框图形表示出来。在教学中恰当地运用这种图示教学,有利于指导学生总结、巩固知识,降低知识的学习难度,激发学生学习的兴趣。近年来,笔者在这方面作了一些尝试,收到较好的教学效果。 The graphic method described in this article is to use the intuitive, concise and logical block diagram form to connect the internal knowledge of students. Appropriate use of such graphic teaching in teaching can help guide students in summarizing and consolidating knowledge, reducing the difficulty of learning knowledge, and stimulating students’ interest in learning. In recent years, the author made some attempts in this area and received better teaching results.
