笔者从事化学教学17年,对化学实验教学有自己的一些看法和见解。在课堂教学中不断对演示实验进行改进和创新,以期达到演示实验的最优化。下面就以沪教版教材(2012年7月版)第3页碳酸氢铵受热分解这个实验为例,谈一谈对其进行的改进和创新,以期通过交流,再次提高。一、教材中实验1.实验仪器和药品仪器:蒸发皿、三脚架、酒精灯、小木块;药品:碳酸氢铵。
I engaged in chemistry teaching for 17 years, some of my own views and opinions on chemistry experiment teaching. In the classroom teaching constantly improve the demonstration experiment and innovation, in order to achieve the optimization of demonstration experiments. Here to Shanghai PEP textbook (July 2012 edition) third page of ammonium bicarbonate thermal decomposition of the experiment as an example, talk about its improvement and innovation, with a view to further enhance exchanges. First, the textbook experiment 1. Experimental equipment and pharmaceutical equipment: evaporating dish, tripod, alcohol lamp, small wooden; drugs: ammonium bicarbonate.
