Research On Teaching Design And Ability Assessment Of High School Chemistry Modeling

The continuous development of curriculum reform and the continuous updating of teaching methods have brought a lot of room for development for the innovative model of chemistry curriculum.This study responds to the new curriculum standard of 2017,which requires subject teaching to cultivate students' core literacy as the basis,taking "model cognition and evidence reasoning" as the research focus,summarizing the research results of modeling teaching at home and abroad,designing modeling teaching design based on students' experience,at the same time for the modeling process embodied in the ability to differentiate and according to academic quality standards and previous experience of different levels of ability,in order to explore the role of modeling teaching in improving students' modeling ability in different aspects,so as to demonstrate the feasibility and effectiveness of modeling teaching.Based on the core concept of redox,this study combined the concept of redox with the original battery model to correct the different conceptions,clarify the logical relations of model elements,and systematize and structure the knowledge.
