在现代的化学课堂教学中,学生不再是被动地接受基础知识和基本技能,而应该成为积极主动的学习主体。在化学课堂教学中,创设适当的问题情境是解决这一问题的最有效的教学形式。笔者从对问题情境的界定和理解、创设问题情境的途径以及创设问题情境应注意的问题三个方面对此进行了深入思考。 In modern chemistry classroom teaching, students no longer passively accept the basic knowledge and basic skills, but should become the active learning subjects. In chemistry classroom teaching, setting up appropriate problem situations is the most effective teaching method to solve this problem. The author thinks deeply from three aspects: the definition and understanding of the problem context, the way of creating the problem context, and the problems that should be noticed when creating the problem context.
