核心素养导向下相同情境素材不同题型的命题实践与反思——二氧化碳人工合成淀粉

Add to Favorite Setting Questions with Same Context and Different Types Under Guidance of Core Literacy:CO_(2)to Synthetic Starch

同“素”异构即针对同一素材分别以不同题型跨模块甚至是跨学科进行深挖,测试学生化学学科核心素养的不同学业质量水平。以前沿学术探索情境“二氧化碳人工合成淀粉”作为命题素材,分别从化学反应原理、物质结构与性质、有机化学基础等3种呈现形式原创3道大题。同“素”异构,有利于提升学生从真实情境中提取加工信息的能力;有利于提升学生知识关联结构化的水平;有利于拓展学生思维的宽度和深度。

The same context and the different types means that the students'different academic quality level of chemistry core literacy is tested through in-depth exploration of the same material with different question types and even across disciplines.With the cutting-edge academic exploration scenario“CO_(2) to synthetic starch”as the topic material,three original topics are created from the three presentation forms of chemical reaction principle,material structure and properties,and organic chemical basis.This question setting way is beneficial to improve students'ability to extract and process information from real situations;It is conducive to improving the level of students'knowledge relevance and structure;It is beneficial to expand the width and depth of students'thinking.
