Research On The Cohesive Training Strategy Of The Core Literacy Of "Changing Ideas And Balancing Thoughts" For Junior And Senior High School Students

The new curriculum standard clearly proposes to cultivate and develop the core qualities of students in chemistry.Among them,"change concepts and balance ideas" is an important part of the students' thoughts and methods for forming the chemistry discipline,as well as an important idea for students to study and explore chemistry.Based on the literacy of "changing ideas and balancing thoughts",the thesis compares the differences and symbiosis between the third grade and the first grade from the content selected from the textbooks and the training objectives,and proposes the cultivation of the core literacy of "changing ideas and balancing thoughts" for junior high school students Strategy.Based on the relevant literature research and the content of the third-year students' learning,the thesis selects "The Law of Conservation of Quality" as the teaching content,carries out teaching design,conducts teaching practice in the experimental class,uses questionnaire surveys and chemistry scores as evaluation tools to test the effectiveness of the strategy,Combined with teacher interviews,draw conclusions,in order to provide reference and reference for teachers' teaching and students' learning.The research is divided into six chapters:The first chapter mainly introduces the background,content and research significance of the selected topic.It explains the feasibility of this research from the two perspectives of the new curriculum standard for middle school students' "changing ideas and balancing ideas" and the current problems in classroom teaching..Through the literature,the status quo of the cultivation of this literacy at home and abroad was understood,and the research significance and content of this article were clarified.Chapter Two discusses the definition of related concepts and the theoretical basis.The third chapter analyzes the curriculum standards based on the literacy of "changing ideas and balancing thoughts".It mainly compares and analyzes the differences and symbiosis between the third grade and the first grade from the content of the teaching materials and the training objectives.Chapter 4 conducted interviews with first-line teachers of chemistry in the third grade of junior high school,to understand the current situation and problems of the current training of "changing concepts and balanced thinking" for junior students.The following teaching strategies are proposed for the cultivation of this quality of junior high school students:(1)Pay attention to the study of the theory of "change concept and balance thought"(2)Deepen the depth of experimental teaching,pay attention to the protection of students' interest(3)Combine macro and micro,construct a knowledge framework(4)Combine digital education to form intuitive experience.The fifth chapter is the cohesive practice research on the cultivation of "concepts of change and balance of thought" for the first grade of junior high school students.According to the theoretical research in the previous article,the "Law of Conservation of Quality" is selected as the teaching practice content,and the teaching practice is carried out in the experimental class.A pre-test was conducted on two classes,and a post-test was conducted on the two classes after the teaching practice.Questionnaire surveys were conducted in the experimental class and the control class,and the final chemistry scores of the two classes were analyzed.As an evaluation tool,teachers were interviewed,data collected,and analyzed,and the following conclusions were drawn: This training strategy can effectively promote the development of students' "changing ideas and balancing thoughts".The sixth chapter summarizes the conclusions of this study,and put forward relevant prospects.
