Design And Practice Of Ionization Equilibrium Teaching Based On Deep Learning Theory

The ionization balance is based on the electrolyte solution and chemical equilibrium,lays a foundation for the salt hydrolysis and precipitation solution balance.It plays an important role in high school chemistry learning and is also a difficult part in high school chemistry teaching.How to help students better grasp the ionization balance,implement curriculum standards requirements,develop the key competencies of chemistry? Taking this as the starting point,this paper obtains the teaching status through literature analysis and teachers interview,designs the ionization balance teaching case on this basis and applies it to teaching practice,and draws some conclusions after students interview and questionnaire analysis.This paper is divided into five chapters for research:The first chapter is the introduction,mainly introduces the background of the topic,makes a literature review of the existing research,and determines the research ideas and methods.The second chapter analyzes the content of ionizing equilibrium knowledge from the perspective of key competencies from the aspects of curriculum standard,college entrance examination outline and textbook content.The third chapter is the key content of this study.Based on the foundation of the previous two chapters and teacher interviews,the teaching design of "competency oriented" is carried out for the two sections of "ionization of weak electrolyte" and "ionization of water and acidity and alkalinity of solution" based on the deep learning theory.The fourth chapter is to select the practical objects to practice after completing the teaching design,and analyze the results to learn from the reflection experience.The last chapter is a summary and discussion,and a reflection on the shortcomings of the research.Through research,it can be found that students are more accepting of the teaching mode based on the deep learning theory,which can fully integrate into the teaching activities in the classroom,the level of knowledge acquisition has been significantly improved,and their learning enthusiasm and interest have also been improved.In addition,compared with traditional teaching,the teaching based on deep learning theory can improve students' high-order thinking ability such as analysis,evaluation and creation.
