在化学课堂教学中,根据不同的情况、课型创设具体的问题情境,是学生自主探究化学知识的起点、动力和源泉;是提高学生学习化学能力的一种有效手段。怎样创设问题情境,创设情境应注意哪些问题,笔者结合自己的教学经验,摸索出几种比较常用的情境教学法:比较性问题情境、过程性问题情境、思维性问题情境、兴趣性问题情境、经验性问题情境等。
In the chemistry classroom teaching, according to different situations, the textbook creates the specific problem situation, which is the starting point, motive force and source of students ’independent exploration of chemical knowledge. It is an effective way to improve students’ ability to learn chemistry. How to create a problem situation and create a situation should pay attention to what the problem, the author combined his own teaching experience, to explore several commonly used situational teaching methods: comparative problem situation, process problem situation, thought problem situation, interest problem situation, Experience problem situation and so on.
