Design And Application Research Of High School Chemistry Experiment Teaching In 2019 PEP Edition

The term "chemistry core literacy" replaces the three-dimensional goal in the "chemistry curriculum standard of senior high school(2017)"(hereinafter referred to as " 2017").As an important learning content and method of chemistry,chemistry experiment contains a unique understanding angle of chemistry,which is bound to become an important strategy and way to cultivate students' discipline literacy.How to make good use of the chemistry experiment and design the experiment teaching plan in the textbook to promote the realization of the core literacy training goal has become a new research topic.This paper takes the experimental part of the 2019 textbook as there search object(hereinafter referred to as 19),and the research content divided into two parts: experimental teaching design and practical application.In the experiment teaching design part,on the basis of combing the different meanings of the new core literacy concepts at home and abroad,a comparative study of the old experimental textbooks at home and abroad is carried out,and the senior high school experiment teaching strategies are explored according to the cognitive theory,Bandura learning theory,and the layout of the new textbooks.The four types of experiments(experiment,inquiry,experimental activity,research and practice)in the textbook are designed in an advanced way.In the case,the concept of cultivating student literacy is reflected,which meets the requirements of cultivating students' higher-order thinking and literacy.In the practical application part,one or two classes of grade one in a middle school in Fuzhou City are selected as the teaching practice objects to carry out the case teaching practice.Through questionnaire survey and analysis of the results of practice activities,it is found that there is a significant improvement in the cultivation of students' chemistry core literacy.At the same time,familiar with the connotation of the experiment,deep digging the literacy elements contained in the experiment,teachers can effectively carry out the experiment literacy teaching.
