化学概念既是化学学习的基础,是化学学习的依据。由于化学概念常常不仅包含概念本身的含义,而且常常包括一些化学原理、化学反应规律等内容,因此,化学概念教学是化学教学的一个非常重要的内容。化学概念表述简洁、严密、完整、科学,每个词语都有其特定的含义,搞好化学概念教学是搞好化学教学的重要基础。通过多年的化学教学实践,我感到,要搞好化学概念教学必须做到“三个讲清”。
The concept of chemistry is not only the basis of chemistry study but also the basis of chemistry study. Because the concept of chemistry often includes not only the concept itself, but also often includes some principles of chemistry, chemical reactions, etc. Therefore, the concept of chemistry teaching is a very important part of chemistry teaching. The concept of chemistry is concise, strict, complete and scientific, and each term has its own specific meaning. To improve the teaching of chemistry concept is an important foundation for chemistry teaching. Through many years of chemistry teaching practice, I feel that we must do “three clarification” to do a good job of teaching chemical concepts.
