初中化学是中学生进入九年级新接触的一门课程,是一门以实验为基础的自然科学,教学中一些有趣的化学实验会激发中学生的学习兴趣,但课本中大量的化学基本概念和知识点却成为学生的一大难题,学生对很多抽象的化学知识难以理解,给他们学习化学和掌握化学知识带来了困难,也给教师的教学增添了难度。下面,笔者结合自己的教学实践,提出一些行之有效且操作性强的方法,供同仁探讨。一、利用打比方,帮助学生理解 Junior high school chemistry is a new course of high school students entering the ninth grade. It is an experiment-based natural science. Some interesting chemistry experiments in teaching will stimulate the interest of middle school students in learning. However, a large number of chemistry basic concepts and knowledge points Has become a major challenge for students. Students find it difficult to understand many abstract chemical knowledge, which makes it difficult for them to learn chemistry and master chemical knowledge. It also makes it more difficult for teachers to teach. The following, the author combined his own teaching practice, put forward some effective and operational method for my colleagues to explore. First, the use of analogy, to help students understand
