Research On Oftlineleaded Blending Learning Of Physics In Senior High School Based On STSE Concept

With the ever-increasing speed of contemporary information technology update,basic education must keep up with the development of the times,use information technology to carry out education and teaching work,and carry out educational reform.This also prompts high school physics teachers to change the educational concept of the times and innovate teaching methods.In order to cooperate with my country’s basic education curriculum reform and promote the construction of physics curriculum,the teaching goal of physics has changed from cultivating students’ knowledge construction to cultivating students’ physical literacy and ability,and the teaching content is also constantly updated.All these put forward new requirements for physics teaching.In view of the lack of a more systematic teaching implementation method in domestic STSE education,this research proposes a hybrid teaching concept under the STSE education concept,carries out a middle school physics teaching design under the STSE concept combined with the characteristics of micro-lecture videos,and proposes an offline-led model.STSE instructional design strategies and case studies under blending learning.The thesis is divided into five parts:The first part,through literature reading,summarizes the research results and current situation of STSE teaching at home and abroad;compares the advantages of blended education teaching research in my country and the international frontier and the implementation in high school physics,and develops teaching theory and teaching design in high school physics teaching and practice.The second part,the concept definition and theoretical basis of core nouns.The theoretical basis includes blending learning,the connotation of STSE education,and selects cognitive development theory,Vygotsky’s development view,cognitive-discovery learning theory,humanistic theory,pragmatism teaching and constructivism teaching and other theories.The third part is the construction of the blending learning model under the STSE education concept.The new status of teachers in blended learning is analyzed,the general process of blended learning construction is given,and the principles and strategies for the construction of physical blended learning based on the STSE concept are proposed:(1)Create social problem scenarios,carry out heuristics Teaching;(2)Apply the history of physics to penetrate STSE education;(3)Use STSE test questions to focus on the cultivation of problem-solving skills;(4)Make reasonable use of video micro-lectures to strengthen the connection between STSE content and physics classrooms;(5)Reasonable Use network resources to bring experiments into the classroom.According to different types of physics classrooms,the design and analysis of blended learning cases under the STSE concept are carried out.The fourth part investigates the application status of blended learning in high school physics and teachers’ acceptance of blended learning,and investigates the penetration status of STSE educational concepts in physics teaching.The questionnaires were used to learn about the online practice of physics teachers and their understanding of blended learning in physics teaching.Through the questionnaire,we learned about the current high school physics teachers’ understanding of STSE education,the selection of educational resources and the application of teaching media,and the difficulties encountered by teachers in STSE teaching.There is a certain understanding of education,but there is a lack of in-depth study(2)the lack of STSE educational resources,and the STSE content of textbooks has not been fully utilized;(3)high schools ignore experimental teaching,and students lack practical conditions;(4)STSE education can promote students Follow STSE and get interested in studying physics.The fifth part,combined with the general process of blended learning,gives a complete blended learning design under the STSE concept.It includes three typical teaching design and teaching methods including the experimental class-"Experiment: Measuring the Average and Instantaneous Velocity of Paper Tape",the law class-"Free Fall Motion" and the concept class-"Synthesis and Decomposition of Forces".Effectiveness analysis.Finally,the conclusions and prospects of the research are summarized:(1)Blended learning based on STSE concept can make current physics classroom teaching full of vitality(2)Blended learning under the guidance of STSE can improve students’ ability to solve practical problems(3)The author It is believed that the blended learning under the STSE educational concept deserves the attention of more educational researchers.
