Advanced Study On The Topic Of "Energy" In Physics In Junior High School

Since the core concepts and the theory of advanced learning were proposed,the construction of advanced learning framework based on core concepts has been a hot topic in the field of education.In 2022,China promulgated the 2022 edition of the compulsory education physics curriculum standards.The promulgation of the new curriculum standard has brought new problems to teachers’ teaching and curriculum connection.The theme of "energy" is one of the five first-level themes of the new curriculum standard,and the construction of the advanced learning framework of the junior high school physics "energy" energy theme based on the new curriculum standard has not been studied.Therefore,summarizing the core concepts of the theme of "energy" in junior high school physics in China,and constructing an advanced learning framework based on these core concepts,is of great significance for teachers’ teaching,students’ learning,curriculum integration,exam evaluation,etc.Based on the above understanding,this article has formulated two research contents.The first research content: What are the core concepts under the theme of "energy" in junior high school physics in China? The second research content: What is the learning level of the core concepts under the theme of "energy" in junior high school,that is,to what extent should students of each grade in junior high school understand the core concepts under the theme of "energy".To achieve the above research objectives,this article will adopt methods such as literature analysis,questionnaire survey,and interview.The specific research steps are divided into six parts.The first part is to review relevant literature both domestically and internationally,analyze the research background and current situation of learning advancement,summarize the research purpose and significance,and develop research methods.The second part investigates the definition and theoretical basis of advanced learning,core concepts,energy,and other concepts;The third part starts from the new curriculum standards and combines with the high school entrance examination papers in Zunyi City in recent years to analyze the level that students should reach in learning the relevant concepts of the "energy" theme,screen out the core concepts of the "energy" theme,and combine the "Shanghai Science Edition" physics textbooks used in local teaching,as well as the situation of internship schools and suggestions from school teachers,to establish a learning level for the "energy" theme.Establish an advanced learning framework that aligns with students’ cognitive development level;In the fourth part,according to the learning framework,a pre-test questionnaire of "energy theme learning" was developed to conduct quantitative research on the advanced level of 202 students in five classes of Grade 8 and Grade 9 of junior high school in the laboratory school affiliated to Zunyi Normal University from five dimensions.Two dimensional analysis of "accuracy-concentration ratio" is carried out for each group of data to determine the current advanced level of relevant concepts of students in each grade;The fifth part proposes teaching suggestions based on the energy advancement framework and summarizes and reflects on the problems and deficiencies in the research process.Through the above research process,the following research conclusions have been drawn: there are two core concepts of energy in junior high school physics: the form of energy,the transfer and transformation of energy;Obtain a conceptual relationship diagram under the theme of "energy" in junior high school physics;We have constructed an advanced learning framework under the theme of "energy".In response to the issues reflected in the research results,some suggestions were put forward for the teaching of relevant concepts related to the theme of "energy".
