实验是化学课程的基础。高中化学教学应将实验和学生的生活经验相结合,让生活情境以实验活动的形式在课堂中再现,让化学实验在学习活动中不断丰富,使学生在实践中体验,在体验中成长,让课程真正成为沟通学习与生活的桥梁,最终实现教育教学的目的。钠的化合物一课的教学,要求学生掌握过氧化钠的性质及其用途,初步掌握碳酸钠、碳酸氢钠的性质及其性质差异,以及它们的用途。下面以此做分析点评。
Experiment is the basis of a chemistry course. Chemistry teaching in high school should combine the experiment with students’ life experiences so that life situations can be recreated in the classroom in the form of experimental activities. As a result, chemistry experiments are continuously enriched in learning activities so that students experience in practice and grow in experience so that Courses really become a bridge between learning and life, and ultimately achieve the purpose of education and teaching. The class of sodium compounds teaching requires students to master the nature of sodium peroxide and its use, preliminary grasp of the nature of sodium carbonate, sodium bicarbonate and its nature differences, and their use. Here to do analysis of comments.
