基于实证的碘元素及其化合物高三专题复习探究活动设计

Inquiry Activity Design of Special Review of Iodine and Its Compounds

高三元素化合物专题复习要关注学生探究意识的提升和解决情境探究问题思维框架的搭建。在元素化合物探究活动设计中，将有关碘及其化合物的物质转化过程和探究反应中“异常现象”的原因进行有机整合，围绕如何设计实验方案开展实证活动，搜集证据证实或证伪猜想来展开教学。阐述了探究活动设计的思路与开展方式，形成了解决问题的一般思维模型，并进行了教学反思。

Special review of element compounds in senior three should pay attention to the promotion of students＇ inquiry consciousness and the establishment of the thinking framework of situational inquiry. In inquiry activity design of element compounds, this paper integrated the process of substance transformation of iodine and its compounds and the reasons for ＂abnormal phenomena＂ in the reaction, carried out the teaching around how to design the experimental scheme to carry out empirical activities, how to collect evidence to prove or disprove the conjec- ture. This paper expounded thoughts and implementation methods of inquiry activity design, and formed the general thinking model of solving the problem, and made teaching reflections.
