摘要:

将STEM (Science, Technology, Engineering, Mathematics)教学理念融入应用化学实验的SPOC (Small Private Online Course)线上线下混合式教学,采用针对不同实验项目的案例式教学法,学生课前完成实验讲义和视频的线上预习,线下针对案例问题,综合运用多学科知识分组讨论,在教师指导下解决问题并提出实验方案,进行实验操作,在课后进行STEM教学评价。以上教学手段的实践将线上教学资源和线下实验操作有机融合,促进学生自主学习,实现对学生科学精神与合作创新能力的培养。

关键词: STEM理念, 混合式教学, 应用化学实验

Abstract:

We integrated STEM (Science, Technology, Engineering, Mathematics) teaching concepts into SPOC (Small Private Online Course) blended teaching of applied chemistry experiments, and adopted the case teaching method for different experimental projects. Students completed online previews of experimental contexts and videos before class and discussed and analyzed the cases in groups during class. With teacher guides, the students provided solutions and conducted experimental operations. Effective STEM evaluation was used after class. Practicing the above teaching methods organically integrated online teaching resources and offline experimental operation, promoted students' autonomous learning, and cultivated students' scientific spirit and cooperative innovation ability.

Key words: STEM concept, Blended teaching, Applied chemistry experiment
