在以往的教学实践中发现,有一部分学生因为不理解“物质的量”这一概念,而失去对化学学习的兴趣,甚至有放弃学习化学的念头。因此,我特别重视“物质的量”这一章节的教学。“物质的量”是化学中一个很重要的基本概念,然而“物质的量”这一概念对学生来说非常抽象、难 In the past teaching practice, some students found that because they did not understand the concept of “quantity of matter”, they lost their interest in chemistry and even gave up their idea of ​​learning chemistry.
