数字实验以真实实验为基础,通过各种传感器替代传统的仪表,将实验数据采集之后交由计算机分析处理,能够更加清晰、明确地展示现象,揭示规律。人教版普通高中课程标准实验教材必修1第三章金属及其化合物第56页中的“科学探索”栏目,就有碳酸钠和碳酸氢钠的热稳定性比较实验,笔者用数字化手段完成了该实验,取得了较好的效果,是一次有益的尝试。
Digital experiments based on real experiments, through a variety of sensors to replace the traditional instruments, the experimental data collected by the computer analysis and processing, to be more clearly and clearly show the phenomenon and reveal the law. People’s Pupils of ordinary high school curriculum standard experimental materials compulsory 1 Chapter III of metals and their compounds page 56 in the “scientific exploration” section, there is sodium carbonate and sodium bicarbonate thermal stability of comparative experiments, I use digital means Completed the experiment, achieved good results, is a useful attempt.
