Research On The Teaching Design Of High School Chemistry Project-based Learning Based On STSE Education

With the development of technology and the progress of education,the society's demand for innovative and comprehensive talents is increasing day by day.Countries around the world gradually focus on the development of project-based learning in talent training to cultivate students' comprehensive ability emphatically.This study teases the development history and research status of project-based learning and STSE education at home and abroad.The cognition degree of project-based learning of the front-line chemistry teachers was investigated by questionnaire survey.The educational concept of STSE emphasizes the connection between scientific knowledge and science,technology,society and environment to cultivate the practical ability of students.In this study,the chemistry STSE practical education in high school is chosen to develop and research the teaching design of project-based learning,so as to realize the penetration and application of project-based learning in chemistry teaching.By analyzing the basic elements of project-based learning,this study establishes the theoretical framework of project-based learning and combs the content of STSE educational practice activities in high-school chemistry textbook.The recycling of waste lithium ion battery is identified as the project theme to develop the teaching design of project-based learning,which guides the student to complete three projects in the form of group work "the battery drawing" "investigation report" and "technological process".In order to expand extracurricular resources,the author made general science micro-courses with related to lithium ion battery science knowledge.Instructional design is oriented to the project problems in real situations,guiding students to study independently,cultivating the cooperative consciousness and practical ability of students,improving scientific literacy and social responsibility of students.Finally,five experts are invited to evaluate the feasibility and scientificity of the instructional design.Based on the expert opinions,the author modifies the instructional design to make it more in line with the requirements of project-based learning education concept.
