教学难点可以从基础知识和基本技能两方面来确定,也就是学生不容易理解的概念、原理、定律法则、公式等知识可以认为是难点,对于那些应用基础知识去解决某些实际问题而感到困难,或是通过反复训练学生难以内化的知识也可以认为是难点。就是对学生不容易理解的知识,教师要启发讲解,运用演示实验的方法来攻破教学难点,运用比喻的方法帮助学生理解知识。
Difficulties in teaching can be determined from two aspects: basic knowledge and basic skills, that is, concepts, principles, laws and formulas that students can not easily understand can be regarded as difficult points and difficult for those who apply basic knowledge to solve some practical problems , Or by repeatedly training students to be difficult to internalize the knowledge can also be difficult. Is not easy for students to understand the knowledge, teachers should inspire explanations, the use of demonstration experiments to break the teaching difficulties, the use of metaphor to help students understand the knowledge.
