PBL协同翻转课堂下的元素化学教学——以卤素含氧酸及其盐的课堂教学为例

Flipped Classroom with PBL in Teaching of Chemistry of the Elements:Taking the Teaching of Haloid Oxyacids and Haloates as an Example

针对“知而后行”传统课堂教学模式在元素化学教学中存在“教者吃力,听者乏味”的教学现状,以“卤素含氧酸及其盐”的教学设计为例,设计情境问题,通过PBL(以问题为导向)教学法协同翻转课堂,实施以学生为中心的“知行合一”教学模式。本教学实践为卤素章节的翻转课堂教学改革提供了流程再造、范式重建和模式创新的思路。

In response to the current situation that the traditional classroom teaching mode of“knowing and then doing”in chemistry of the elements is“hard for the teacher and boring for the listener”,we took the teaching design of“halogenated oxygenates and their salts”as an example.We designed situational questions to implement a student-centered“doing while knowing”teaching mode through the PBL(problem-based learning)teaching method and the flipped classroom.This teaching practice provides ideas for process reengineering,paradigm reconstruction and model innovation for the flipped classroom teaching reform of the halogen chapter.
