%X 在“配制一定物质的量浓度溶液”教学中，教师会经常困惑是在溶液配制开始之前介绍容量瓶的使用还是在溶液配制之后总结容量瓶的结构和用途，本文通过对比分析人教版和鲁科版两种教材在“配制一定物质的量浓度溶液”教学中教材的编写顺序，整合两种教材的优缺点，探索出了一种启发性较强的教学设计，便于学生理解容量瓶这种仪器的结构和用途。
In the teaching of “preparing a concentration solution of a certain substance”, teachers often confuse whether to introduce the use of volumetric flasks before the solution preparation or summarize the structure and purpose of volumetric flasks after the solution preparation. This article compares and analyzes the order of textbook writing in the teaching of “preparing a concentration solution of a certain substance” between the People’s Education Press and the Lu Ke Press, integrates the advantages and disadvantages of the two textbooks, and explores a highly inspiring teaching design to facilitate students’ understanding of the structure and purpose of volumetric flasks as an instrument.
