近两年来,各地在教学中普遍加强了电化学内容,有关电化学的习题也显著增加,试图有效地提高电化学部分的教学质量。笔者认为,按照现行教学大纲规定的范围,提高中学电化学教学质量的关键不在于搞大量的习题,而在于引导学生弄清电化学初步原理,掌握电化学基本概念,其中电极概念是很重要的一个方面。 In the past two years, the contents of electrochemistry have been generally strengthened in teaching. Electrochemical exercises have also increased significantly, and attempts have been made to effectively improve the teaching quality of the electrochemical part. The author believes that, in accordance with the scope of the current syllabus, the key to improving the quality of electrochemistry teaching in secondary schools is not to engage in a large number of exercises, but to guide students to understand the basic principle of electrochemistry and master the basic concept of electrochemistry, in which the electrode concept is very important. One aspect.
