Practical Research On Developing The Core Literacy Of "Evidence-Based Reasoning And Model Cognition" Based On Chemistry Experiment

The 21 st century is an era that emphasizes core literacy.Core literacy is the basis for personal lifelong development and sustainable development,and the cultivation of talents cannot be separated from the implementation of core literacy.In our country,the discipline core literacy is the starting point of core literacy.It is the concrete of core literacy,reflects the unique contribution of the discipline to core literacy,and is the soul of discipline education.The "General High School Chemistry Curriculum Standards(2017 Edition)" lists five chemistry discipline core literacy.How to promote their implementation is an important proposition for chemical education teaching research.In the field of chemistry,experimental teaching is important and irreplaceable,and it is closely related to the cultivation of core literacy.This study uses the improvement of the literacy of "evidence-based reasoning and model cognition" as the entry point,and promotes the implementation of the core literacy by improving the design of experimental teaching classrooms.The full text consists of five chapters: the first chapter is the introduction,introduces the research background,reviews the current status of domestic and foreign research,clarifies research ideas and research methods,and analyzes the purpose and significance of this research.The second chapter is the conceptual definition and the theoretical basis,which mainly expounds the educational theory of the important concepts and teaching design improvements involved in this article.The third chapter is an investigation of the current situation of experimental teaching and core literacy.Through the investigation and interviews of the teacher and student of the author’s internship school,grasp the development of the core literacy of students,tap the current insufficient experimental teaching,and determine the improvement of the implementation of the discipline core literacy.The fourth chapter is teaching practice based on the development of "evidence-based and model cognition" based on the development of chemistry experiment.According to the specific problems and related theories of the school,three aspects of teaching improvement measures are proposed.Design two sections of experimental teaching improvement courses with the content of the "primary battery" module as the carrier.Through the quasi-experiment,the experimental class and the control class adopted the improvement of experimental teaching and traditional teaching.Comparing the test scores and interviews some students to detect the effects of the course and reflected insufficient reflection.The fifth chapter is a conclusion,summarizes the research conclusions,reflects insufficient research,and looks forward to follow-up research content and direction.This study concludes that students’ literacy of "evidence-based reasoning and model cognition" can be developed based on chemistry experiment.The specific improvement measures include: utilizing task-driven teaching to activate student thinking,expanding the experimental materials to promote integrated knowledge,and using comprehensive performance assessment to diagnose competency development in a timely manner.To design a classroom for competency-based experimental teaching,a comprehensive understanding of the chemistry discipline core literacy is a prerequisite.Integration of teaching content is the foundation,understanding and respect for students are crucial,and careful design of experimental inquiry ensures effectiveness.
