基于CAFPC教学模式的社会性科学议题单元教学设计——新型甜味剂的使用

SSI Unit Teaching Design Based on CAFPC Teaching Mode:Use of Novel Sweeteners

在科学课堂中开展社会性科学议题教学能够增进学生科学思维的发展,促进学生科学态度与社会责任的形成,加深学生对科学观念的理解。构建由“直面情境、问题剖析、议题聚焦、实践应用、模型建构”5阶段组成的CAFPC教学模式用于SSI单元教学,具有较强的可操作性、实用性及适切性。以“新型甜味剂的使用”社会性科学议题为例,将其蕴含于“无糖饮料”系列情境贯穿于整个教学过程,应用CAFPC教学模式进行SSI教学,以期推动SSI教学在科学课堂的真正落实。

Teaching socio-scientific issues in science classroom can promote the development of students'scientific thinking,promote the formation of students'attitudes and responsibili-ties,and deepen the understanding of students'scientific concepts.The CAFPC teaching mode,which consists of five stages of""confronting the situation,analyzing the problem,focusing on the issue,practical application and model construction",is constructed for SSI unit teaching,which has strong operability,practicability and suitability.Taking the socio-scientific issues of"use of novel sweeteners"as an example,the series of situations contained in the"sugar-free beverage"run through the whole teaching process,and the CAFPC teaching mode is applied to SSI teach-ing,in order to promote the real implementation of SSI teaching in science classes.
