Research On The Development Of Junior High School Chemistry Project-based Teaching Cases Based On Core Literac

"Chemistry Curriculum Standards for Compulsory Education(2022 Edition)" presents new opportunities and challenges for core literacy.Traditional teaching methods are difficult to implement all core literacy.Therefore,teachers should constantly learn advanced educational concepts,try different teaching methods in teaching activities,and reform students’ learning activities.In recent years,more and more researchers and teachers pay attention to project-based teaching.However,in the implementation of project-based chemistry teaching in junior high school,we need to think and solve the following problems:how to construct the case development system of project-based chemistry teaching;How to develop project-style teaching cases based on core literacy connotation;How to implement chemistry project teaching in classroom teaching.By issuing and recovering questionnaires,this study investigated the status quo of junior high school chemistry teachers’ cognition of core literacy and project-based teaching.Through analyzing the questionnaire results,it was concluded that: first,junior high school chemistry teachers’ cognition and understanding of project-based teaching were not deep enough,and their ability to develop project-based teaching cases needed to be improved.Second,teachers need to learn theoretical knowledge about the construction of project-style teaching case development system and the operation process of developing project-style teaching cases.Thirdly,it is necessary to develop and design mature project-style teaching cases based on core literacy to provide reference for front-line teachers.This research focuses on the above issues.The main contents of this research are as follows: First,through theoretical research,a project-style chemistry teaching case development system is constructed,which includes content selection and goal formulation,material collection and problem design,tool support and activity organization,process evaluation and goal achievement;The second is the case development system based on the construction of chemistry project-based teaching.The case development process of project-based teaching is defined as four stages: establishment of project theme,dismantling of project tasks,design of learning activities,design of evaluation program;The third is to develop and design two junior high school chemistry project-style teaching cases,"Treating goldfish with potassium permanganate solution" and "Exploring the working principle of lighter",for the reference of front-line teachers.
