Research And Practice Of Visualization Teaching In High School Physics And Mechanics Teaching

Under the background of educational reform,how to improve students' independent learning ability and cultivate innovative talents has become a common concern of many teachers.Mechanics is the first physical knowledge that high school students have access to,and it is also the foundation and core of high school physics.Visual teaching is the product of the progress of the times and the renewal of education,which is helpful to improve the teaching effect of mechanics class.It involves novel teaching methods and diverse teaching resources,which are easily welcomed by teachers and students with the support of modern educational technology.This research discusses how to effectively combine visual teaching methods in senior high school physics and mechanics class,using the method of questionnaire and interview to investigate the current learning situation of middle school students and teachers' teaching situation in senior high school physics and mechanics class,it is found that the main problems are:the mechanics content is abstract,the students' participation in class is not high,the teachers' teaching method is single,and the visualization teaching is less popular.At the same time,based on the requirements of physics curriculum standards in senior high school,under the guidance of modern educational theory,modern educational technology theory,situational teaching theory and brain science,the main forms of visual teaching of physics and mechanics in senior high school are summarized,which are: establishment of physical model;scientific experimental inquiry;multimedia and modern information technology.And put forward five major application principles: scientific principle,student-oriented principle,process principle,comprehensiveness principle and feedback principle.Then,the visualization teaching is infiltrated into every link of the mechanics classroom teaching,and the visualization teaching method is compared with the traditional teaching method in the classroom links such as the introduction of new lessons,the explanation of key and difficult points,and the induction and summary,and the application strategies are developed respectively,taking "impulse","force synthesis","Newton's law of motion" as teaching topics,writing teaching cases,teaching practice.Finally,by setting the motivator that in comparative classes and experimental classes of teaching practice,both in the traditional teaching and visual teaching respectively carried out within the selected class teaching,through questionnaires and interviews,to understand the change of students' learning interest,detected the analysis of student achievement through class.In form and Excel software for statistical analysis,through the data analysis,inspection,evaluation and reflection on the researchprocess.Objective: to explore the application of visual teaching in mechanics class,promote student's understanding of mechanical knowledge and application of rich classroom teaching method improvement,to provide first-line teachers teaching reference.Conclusion: before and after the practice teaching,the questionnaire results show that the experimental class has a significant increase in learning interest,the results of the classroom test and the comprehensive test are better than the control class.In mechanics using visual teaching in classroom can promote the development of the students,thus improve the learning ability,preliminary success in the mechanical application of visualization in classroom teaching.The innovation of this research lies in: using the questionnaire to investigate the current situation of the classroom and test the effect of visualization teaching in the mechanics class;Select advantage of the larger visual teaching method,compared with the traditional method;Against practical teaching links of higher class application strategy and make relevant cases.
