所谓的变式训练，是指从不同角度、方式变换事物非本质属性，以认识其本质属性的训练过程。此类训练方式既能加深对所学知识的理解巩固，又能提高学生灵活应用知识解决问题的能力，对教学质量的提高很有益处。本文就如何在化学教学中进行变式训练例谈如下。【例一l」：将等体积 The so-called variant training refers to the training process of changing the non-essential attributes of things from different perspectives and ways to understand their essential attributes. Such training methods can not only deepen the understanding and consolidation of the learned knowledge, but also improve the students’ ability to apply knowledge to solve problems, which is beneficial to the improvement of teaching quality. This article discusses how to perform variant training in chemistry teaching as follows. [Example 1]: Will be equal volume
