The Practice Research Of "5E Learning Loop" Teaching Mode In High School Chemistry Teaching

"5E Learning Loop" teaching model is a teaching model with inquiry as the core to promote knowledge meaningful learning,including "Engagement","Exploration","Explanation","Elaboration","Evaluation" five links.This teaching model emphasizes that students participate in inquiry activities independently in the problem situation with cognitive conflict,and experience the construction process from unbalanced to balanced old and new knowledge,so as to obtain scientific concepts.This study takes the knowledge of "elements and compounds" as an example to carry out effective teaching research on the teaching mode of "5E learning loop",in order to provide some references for the teaching of chemistry in high school.On the basis of summarizing the application research status of "5E learning loop" teaching model in chemistry teaching,this study analyzed the connotation of each link of "5E learning loop" teaching model.Next,taking the students and chemistry teachers of Yuxi No.1 Middle School of Yunnan Province as the research objects,the study and teaching status of "elements and compounds" knowledge were investigated through questionnaire survey.Then it analyzes the principles and strategies of applying "5E learning ring" to the knowledge teaching of "elements and compounds",and forms the teaching design scheme of "elements and compounds" based on "5E learning ring".Finally,the teaching practice is carried out,and the application effect of "5E learning loop" is understood through questionnaire survey and interview,and the practical results are discussed and analyzed.The results show that the teaching mode based on "5E learning loop" is helpful to improve students’ performance in the "elemental compounds" section,is conducive to the development of students’ core literacy in chemistry,and can also improve teachers’ teaching level.
