教学难点是指那些太抽象,离学生生活实际太远,过程太复杂,学生难于理解和掌握的知识、技能与方法。教学难点是由学生接受能力和教材内容两方面来确定的。教学难点可分为整册的难点、章节的难点和一节课的难点,本文所研究的是一节课的难点。难点具有暂时性和相对性。难点内容一旦经过教学被学生理解和解决了,难点就不复存在了,这就是难点的暂时性。同一知识与方法对一些学生可能是难点,而对另一些学生(重点学校)就可能不是难点, Difficulties in teaching refer to those who are too abstract, too far from the student life, the process is too complicated, students are difficult to understand and master the knowledge, skills and methods. Difficulties in teaching is determined by both the acceptability of students and the content of the textbooks. Difficulties can be divided into teaching difficulties of the whole book, the difficulty of a chapter and the difficulty of a lesson, this article is the difficulty of a lesson. Difficulties are temporary and relative. Once the difficult content is understood and solved by the students after teaching, the difficulty no longer exists, and this is the temporary difficulty. The same knowledge and method may be difficult for some students, but may not be difficult for other students (key schools)
