Current Situation Investigation And Strategic Research On Image Method In High School Physics Teaching

In the General High School Physics Curriculum Standards(2017 Edition),it is clearly stated that students should develop necessary characters and key competencies,among which the ability to employ functions and images to solve physics problems is one of the crucial competencies.The college entrance examination is an essential way to test students’ competence and it is quite common for this examination to present the employment as well as application of images.Meanwhile the complexity and abstraction of physics make it difficult for many students to learn physics.Therefore,they lack motivation on physics learning.Images have the significant feature of visualization.And integrating images into physics teaching not only enhances the interest of the class,but also explains and presents complex and abstract physics concepts as well as formulas in a visual way.Image,which is conducive to the development of students’ core literacy in physics and the formation of an efficient class,can contribute to students’ comprehension and learning.Firstly,with literature analysis as research method,this paper has analyzed the research background and literature review from home and abroad with regard to image teaching in physics.And common images in physics teaching are categorized and summarized as well.Secondly,various research methods such as methods of questionnaire survey and teacher interview are conducted to obtain basic data and relevant information regarding high school students’ knowledge of graphs,use of graphs,drawing graphs,attitudes towards the image method,and physics teachers’ attitudes and applications of the image method.Lastly,statistical analysis is employed to compile and analyze relevant information so as to understand advantages and limitations of current use of images in high school physics teaching.The results of the practical investigation demonstrate that generally,physics teachers hold a positive attitude towards applications of image method.However,students mainly have problems such as irregular diagramming,incomplete drawing,weak awareness of using diagrams,weak ability of extracting image information.These problems mainly result from the low priority that teachers and students attach to images in teaching,and that teachers’ own literacy in image competence is not well developed.Therefore,in response to these limitations and with feedbacks and suggestions from front-line physics teachers in teachers’ interviews,this paper proposes relevant practical improvement strategies or teaching suggestions from the side of teacher and in-class teaching.Then,with certain theory as basis and strategy as guide,a teaching clip for an experimental inquiry lesson is designed as an example.This lesson incorporates rich images,which means applying images to actual in-class teaching.And brief feedbacks on the effectiveness of the application in image teaching are summarized.This research hopes to shed some light on the current state of application of the image method in high school physics teaching.In addition,this paper summarizes limitations of the image method in physics teaching,and puts forward corresponding improvement strategies or advices for teaching,with teachers’ suggestions and relevant theories.Teaching clip design is provided as well to diversify physics teaching methods and to offer an idea and render a reference for integrating image into physics teaching.This paper is expected to strengthen front-line physics teachers’ attention on the application of image teaching.
