教学的语言和文字,无时无刻不对学生产生潜移默化的影响。因此,每描述一个现象,每做一个结论,都应该推敲语言文字的正确性,决不能为了片面地追求通俗、生动而发生科学性错误。决不能“想当然”地信口开河。为了做到正确表达,应该深入钻研教材,教材的编写过程中,对每个问题的表达是很斟酌的。一、正确地使用化学用语化学用语是学习化学的一种专用工具,也是化学科学工作者进行传播和交流化学信息的一种重要武器。教学中,化学用语运用不当,容易引起科学性错误。例如:化学反 Teaching language and text, all of the students have a subtle influence. Therefore, every description of a phenomenon and conclusion of every conclusion should be made on the correctness of the language and words, and no scientific mistake should be made in the interest of making one-sided pursuit of popularity and vividness. Must not “take for granted ” to believe it. In order to be correctly expressed, we should study the teaching materials in depth. In the process of compiling the teaching materials, the expression of each question is very appropriate. First, the correct use of chemical terms Chemical terms is a special tool for learning chemistry, but also chemical science workers to disseminate and exchange of chemical information is an important weapon. Teaching, chemical terms used improperly, easily lead to scientific errors. For example: chemical reaction
