化学教学的难点,通常是指因知识本身抽象、深奥,而导致学生的学习产生心理障碍的化学概念、原理、规律,以及因涉及的知识技能要求较高的实验、解题方法等。如何有针对性地采取切实可行的方法来解决难点,是提高化学教学质量不可忽视的关键之一。在选择解决化学教学难点的方法时需把握两点:(1)要站在学生的角度设计方法,使之符合化学教学的基本原则,具有启发性,能为广大学生所接受。(2)对于不同年龄,不同知能层次的学 Difficulties in chemistry teaching usually refer to the chemical concepts, principles, and laws that lead to students’ learning psychological obstacles because of the abstract and esoteric nature of knowledge, as well as the experiments and problem-solving methods that require high knowledge and skills involved. The key to improving the quality of chemistry education is to focus on how to adopt practical and practical methods to solve difficulties. There are two points to be taken when choosing a solution to the difficulty of chemistry teaching: (1) Design methods should be based on students’ perspectives so that they are in line with the basic principles of chemistry teaching. They are instructive and can be accepted by the majority of students. (2) Learning for different ages and levels of knowledge
