化学概念是化学学科建立和发展的基础,是中学化学学习的主要内容。归纳和演绎是两种主要的概念学习的科学方法。化学新课程提出自主学习、探究性学习、合作学习后,归纳法常被用于化学概念教学中,而演绎法则经常遭人批判。然而笔者及课题组成员通过大量实践发现,在概念教学中,归纳和演绎各有所长,缺一不可。 The concept of chemistry is the foundation of the establishment and development of chemistry and the main content of chemistry study in middle school. Induction and deduction are two major scientific approaches to conceptual learning. The new chemistry curriculum proposed autonomous learning, exploratory learning, cooperative learning, induction is often used in chemical concept teaching, and deductive rules are often criticized. However, the author and group members through a large number of practice found that in the concept of teaching, induction and deduction have their own strengths, are indispensable.
