Research On The Application Of Blended Teaching Based On BOPPPS Model In Junior High School Physics Teaching

The student-oriented and teacher-guided teaching concept,which requires all actions of classroom teaching to be carried out around the students,arises in the wave of educational reform for its conforming to the Times.As a student-centered modular teaching model,the BOPPPS(Bridge-in,Objective,Pretest,Participatory learning,Posttest,and Summary)has been applied by many front-line teachers in different fields of teaching for its consistency and outstanding participatory learning step in recent years.In this thesis,a hybrid teaching model of junior high school physics which can integrate online resources and offline classes is constructed based on BOPPPS model.In addition,the relevant teaching strategies are proposed,and teaching cases are designed.Lastly,the feasibility and effectiveness of the above model through teaching practice.The main work and innovation of this paper are as follows:1.The part of current status investigation: Interviews and questionnaires are used to investigate the current teaching status and learning status of each teaching step in junior middle school physics class,as well as students’ attitudes towards relevant teaching models.The survey results show that although most physics teachers have applied the blended teaching mode in teaching and often interact with students in class to improve their attention,students’ attention is still not ideal and their learning initiative is poor.In addition,it is also found that many teachers have a low understanding of the BOPPPS model,but after a little understanding,they have a high acceptance.2.Theoretical research part: According to relevant construction principles,the mixed teaching model of junior high school physics based on BOPPPS model is constructed.The teaching model makes full use of online platforms and resources,and divides offline classes into preparation,teaching and feedback.Classroom teaching is the core link,and according to the characteristics of BOPPPS model,it is subdivided into six sub-links: classroom introduction,proposed objectives,preview test,student time,consolidation and application,and summary and deepening.Based on the relevant teaching theory and experience,the teaching strategy of each link is elaborated,and the online platform and teaching content suitable for this mode are found.3.Practice research part: In the teaching practice,two parallel classes were selected for control experiment.The teaching practice in the recent semester shows that:(1)According to the S-T classroom observation table,the classroom atmosphere of the experimental class is more active,and students’ activities are more active than teachers’;(2)From the perspective of students’ test scores,the results of independent sample T-test show that there are significant differences between the two classes’ scores;(3)From the record of extracurricular activities,the practical ability of students in the experimental class has been improved;(4)According to the interviews of students in the experimental class,students have a high degree of recognition of this model and generally believe that they are more interested in learning physics.Finally,combined with the teaching practice process and results,the teaching strategy is optimized.Theoretical research and practice show that it is feasible and effective to apply mixed teaching based on BOPPPS model to junior high school physics teaching.This model can not only enhance students’ sense of participation in class,but also enhance students’ interest in physics learning,improve students’ cooperation ability and practical ability,and help cultivate students’ core quality of physics.At the same time,the teaching model constructed and the relevant teaching strategies proposed in this paper can also provide certain references for teachers to optimize the design of classroom teaching.
