The Strategy And Case Study Of Junior High School Physics Problem Situation Creation Under The New Curriculum Standard

With the official promulgation and implementation of the "Compulsory Education Physics Curriculum Standards(2022 edition)",compared with the old edition,the new curriculum standards have made corresponding adjustments to the curriculum objectives,curriculum content and teaching suggestions.In particular,the new curriculum standard puts forward that teachers should consciously create problem situations,guide students to find problems,put forward problems,promote students’ active learning,and constantly enhance students’ awareness and ability to use physical knowledge to solve practical problems.In the past,the teaching design concept,teaching method,problem design and solution strategy often adopted in junior high school physics teaching should also be changed and improved timely,encouraging junior high school physics teaching to advocate situational teaching,highlight problem teaching,and consciously create problem situation.In this paper,based on the analysis of the new curriculum standard,through the investigation of teaching materials,exam questions and teaching problem situation creation,put forward the junior physics problem situation creation strategy: using daily life to create problem situation,using experiments to create problem situation,using social science and technology to create problem situation,using the history of physics to create problem situation.Furthermore,specific problem situation cases are created for concept class,regular class and review class,and applied to junior high school physics teaching practice,so as to improve the efficiency of junior high school physics classroom teaching and further develop students’ core physics literacy.This research is divided into six parts:Part Ⅰ: Firstly,confirm the research background and current research problems of problem context creation,then analyze and investigate the research status of situational teaching at home and abroad by consulting data,summarize the research information of problem context creation strategy,master the purpose and significance of the research topic,and elaborate the research ideas and methods used in the research process.Part Ⅱ: study and analyze the core concept definition and theoretical basis of the subject.On the basis of the first part,think about the three core concepts in the subject,namely,situation,problem,problem situation creation.While determining the core concepts,understand and explore the theoretical basis of research.Part Ⅲ: Pay attention to the current situation and deficiency of the problem situation creation strategy in junior physics classroom teaching,and investigate the problem situation creation of textbooks,exam questions and teaching process respectively.Part Ⅳ: Part Four: On the basis of the second and third parts,analyze how to create the problem situation,explore the principle and strategy of the problem situation creation.Part Ⅴ: The fifth part: Apply the strategy of problem situation creation into practical research,expatiate the problem situation creation of concept course,regular course and review course and the practical case of classroom teaching.Part Ⅵ: The sixth part: summarize and reflect on the research topic,summarize the conclusions of this study,as well as the deficiencies in the research process,and the prospect of future research.
