上好一堂化学课,有好的教学导入非常重要。教学实践证明,不同的定向导入对学习成果有不同的影响。本文试就导入在化学课教学中的作用和常采用的方法如直接导入、设问导入、追问导入、讨论导入、对比导入、实验导入、趣闻导入、生活导入和计算导入等导入方法谈点拙见。 A good chemistry class, a good teaching is very important. Teaching practice has proved that different directed orientations have different effects on learning outcomes. This paper tries to introduce the role of the introduction of chemistry teaching and commonly used methods such as direct import, import and export, ask import, discuss import, import comparison, experimental import, introduction of anecdotes, import of life and calculation of import methods to talk about humble opinion .
