Research On The Application Of PBL Model In Junior High School Physics Experiment Teaching From The Perspective Of STEM

With the continuous development of science and technology,the competition for talents is increasingly fierce,and the state has put forward higher requirements for the training of talents in compulsory education.In the traditional junior middle school physics experiment classroom,there are disadvantages such as flexible teaching design and students lack of initiative and creativity in the classroom.And explore the effective fusion STEM(scientific Science,technology Technology,engineering Engineering,mathematics Mathematics English acronym)concept and PBL(Problem-Based Learning English acronym)teaching mode how to apply to junior middle school physics experiment classroom,can realize science,technology,engineering and mathematics of middle school physics experiment teaching,can make up for the shortcomings of junior middle school physics experiment teaching,for our junior middle school physics teaching development.This paper takes the application of PBL model in junior middle school physics experiment teaching from the perspective of STEM as the research object.Firstly,the existing research on STEM concept,PBL teaching mode and physics experiment teaching in junior middle school is sorted out through literature review.Secondly,according to the present situation of physics experiment teaching in junior middle school,the curriculum standard of physics and the teaching content of physics experiment,the research value of this paper is determined.Finally,through the research on the principles and strategies of PBL model physics experiment teaching in junior middle school from the perspective of STEM,the experimental teaching objectives and the design of experimental teaching process are summarized,and four teaching cases are shown.In order to verify the results of the application of PBL mode under STEM horizon in physics experiment teaching in junior middle school,the author set up experimental group and control group in the two classes respectively.First of all,SPSS software was used to analyze the physics results of the first two classes,and after the teaching practice,the test test was analyzed again,which found that the results of the students in the experimental class had improved significantly.Secondly,the hierarchical analysis method and fuzzy comprehensive evaluation method to obtain the evaluation results under this mode are in the excellent range.Finally,by comparing the changes of STEM quality before and after the teacher subjective questionnaire,it was found that the comprehensive quality of students in the experimental class was significantly improved.The above analysis shows that this study has certain value and feasibility.
