分析化学教学中问题解决教学模式的构建

Construction of Problem-solving Teaching Mode in Analytical Chemistry Teaching

以问题为导向,通过教师帮助下的学生自主探索和学习,引导学生在解决问题的过程中掌握知识,培养能力的问题解决教学模式的教学理念和OBE(成果导向教育)思想有很好的契合.本文以"弱酸碱滴定"教学为例,探讨了分析化学教学中的问题解决教学模式的构建,其实施程序由创设问题情境,提供信息,学生自主学习,弥补性教学,变式练习与反馈五阶段组成.

Guided by problems, students explore and learn independently under the guidance of teachers, and they can master knowledge and develop ability in solving problems. The concept of problem-solving teaching mode is in good agreement with OBE thought. Taking “weak acid base titration” as an example, the construction of teaching model of problem solving in Analytical Chemistry teaching was discussed. The implementation process consisted of five stages: creating problem situations, providing information, student independent learning, remedial teaching, variable practice and feedback.
