实验教学是初中化学教学中的重要组成部分,是学生学习知识、探究知识的重要方法。本文笔者结合人教版初中化学教材课例,分别从实验操作、实验现象、实验对比三方面,具体探讨了如何在实验教学过程中设计拓展性问题,以促进学生的思考与探究,提高学生的化学成绩。
Experimental teaching is an important part of junior high school chemistry teaching, which is an important way for students to learn knowledge and explore knowledge. In this paper, the author combined with the lesson plans of the PEP Junior Chemistry Textbook, discussing how to design the expansion problems in the experimental teaching from three aspects: experimental operation, experimental phenomena and experimental comparison respectively, in order to promote students ’thinking and exploration and improve students’ Chemistry results.
