以碳酸钠和碳酸氢钠的性质为例,研究分析高中化学不同模块,探究教学活动。由简单到综合,先扶后放,循序渐进,使学生探究能力逐渐发展。 Taking the properties of sodium carbonate and sodium bicarbonate as an example, we study and analyze different modules of high school chemistry to explore teaching activities. From simple to comprehensive, first support and release, step by step, so that students explore the gradual development of ability.
