摘要
在"氮及其化合物"教学中,利用社会性科学议题"论证重雾霾天气‘汽车限行’的合理性",通过直面议题激发原始想法、探讨汽车尾气与雾霾是否存在关系、探讨汽车尾气是不是导致雾霾的主要原因、面对议题的科学决策的具体教学环节,促进学生掌握氮及其化合物的主要性质,建立从物质类别、元素价态视角研究物质性质及转化的思路方法,促进多个维度核心素养的融合发展。经过多轮次教学改进,结合教学实践过程及其教学效果抽提出真实情境的创设、驱动性问题的设计、课前、课上和课后3个阶段统筹安排等教学策略。
This paper explored the SSI-based instruction of "argumentation the rationality of ‘traffic restriction’ in heavy haze weather" in the teaching of nitrogen and its compounds. By completing the specific teaching procedure: facing the issue to stimulate the original idea, discussing whether there was a relationship between automobile exhausting and haze, discussing whether automobile exhausting was the main cause of haze, making the scientific decision,the students could master the properties of nitrogen and its compounds, establish a thinking method to study the properties and transformation of substances from the perspective of material categories and element valence view, promote the integrative development of multiple dimensions key competencies. After many rounds of teaching improvement, the targeted teaching strategies were drawn on the basis of the process of teaching practice and teaching effectiveness. For example, founding the true scene, the design of driving problems, making the overall arrangement for the three stages: before,during and after class.
