Research On The Application Strategy Of DOPBL Mode In Physics Curriculum In Junior School

Integrated Science is a subject that integrates the process and methods of scientific inquiry.It connects the knowledge of science,the skills of technology,the views in society and the protection of environment with each other,and aims to improve students' scientific literacy based on the understanding of the nature of science.For all students,it helps students to understand nature and science as a whole,deepen their understanding of science,and promote the development of scientific literacy so as to adapt to the development of The Times.However,as an integrated subject,science also faces heavy obstacles in its development.How to embody the comprehensiveness of science curriculum in class and how to cultivate students' scientific literacy through classroom teaching are urgent problems to be solved.In the traditional model of science class,we find that students have a simple grasp of science and technology knowledge,but they have a weak grasp of basic scientific methods and certain application ability to deal with practical problems.Therefore,the implementation strategy of science curriculum which focuses on problem solving and difficult points should be designed by teachers.This study focuses on the DOPBL teaching mode,which combines project-based teaching and problem-oriented teaching mode.Through a series of processes of product design and oriented questions,students' interest can be aroused,and core problemoriented in each link to cultivate students' problem-solving ability.The following works are what I have mainly done during the study:1,under the background of "science" in Zhejiang province based on the subject,physics learning present situation investigation and research: questionnaire survey was conducted to the student,learning condition testing and using MSLQ scale,from the student for self-learning motivation and the understanding of the cognitive strategies of two levels dimension,investigate the relevant aspects,such as actual academic level,problem solving class classroom situation.2.Define and distinguish PBL and DOPBL from the aspects of learning object,learning objective,learning process,learning duration,learning outcome,evaluation method and content.3.Classroom teaching experiment research based on DOPBL mode: Selection of Zhejiang version of "science in the eighth grade teaching material more cases to carry out the actual teaching experiment,through class PTA scale to develop and use,in the class were able to reflect the ability to solve problems related to test,students were tested after the teaching intervention,and the test results and did not receive the teaching intervention peer students compare the test results,To test the feasibility and teaching results of DOPBL model.The main research methods used in this study are: literature method,interview method,questionnaire survey method,empirical research method,quantitative analysis method.The conclusions of this study are as follows:1.The front-line teacher team has certain knowledge and understanding of the "PBL" of the two modes,but the definition of problem PBL and project PBL is confused,and the complete procedure of PBL teaching mode is not clear.PBL teaching mode is mostly used in extended courses or school-based courses,but it is not widely used due to the shortage of class hours in actual classroom teaching.2.DOPBL mode is driven by real situational problems of project-based PBL,which results in the completion of the final project.The problematic PBL promotes continuous reflection and evaluation during implementation,and improves design thinking during this process.Its basic mode is carried out in accordance with the process of selecting projects ? formulating plans ? designing activities ? generating works ?communicating results ? evaluating activities from the point of view of specific operation of project implementation.Internally,the main abilities acquired by students are empathy,definition and conception.The physical and chemical results of the final product shall be communicated and evaluated in the form of product sales.3.Through the analysis of the results obtained from the teaching experiment,it can be seen that the application of DOPBL mode in the physics part of junior middle school science course can produce significant teaching effects on students' independent learning ability and academic performance test results.
