钠与盐、酸反应实验探究式教学

Experimental Inquiry Teaching of Sodium and Salt, Acid Reaction

在新课改的要求下,实验探究式教学应运而生。本文主要是以探究式教学形式来学习金属钠与盐溶液、酸溶液的反应。老师不是直接给出有关化学反应方程式,让学生熟记,而是创设具体的情境,提出问题,引导学生主动发现问题,提出假设,再通过实验来验证自己的猜想。最后总结归纳了金属钠与盐、酸反应的原理。

Under the requirements of the new curriculum reform,experimental inquiry teaching came into being.This paper mainly studies the reaction of metal sodium with salt solution and acid solution in the form of inquiry teaching.The teacher does not directly give the relevant chemical reaction equations and let the students memorize,but create specific situations,ask questions,guide students to actively discover problems,make assumptions,and then verify their own guesses through experiments.Finally,the principle of reaction between sodium metal and salt and acid is summarized.
