Research And Practice Of High School Physical Mechanics Experiment Teaching Based On Core Literacy Of Discipline

The Ministry of Education clearly pointed out that cultivating students' core literacy is the new direction of education reform.Experimental teaching is the foundation of physics,and mechanics occupies an extremely important position in the development of physics,which lays the foundation for high school physical kinematics,electromagnetics,thermals,optics and so on.Therefore,with the help of physical mechanics experiments and specific education and learning theories,the author has carried out research and teaching on the cultivation of the core qualities of students in physics.First of all,the investigation and analysis of the cultivation status of the core literacy of the students' physical disciplines.The survey results show that some students 'physical concepts are relatively vague,and the overall student 's ability to apply physics knowledge to life needs to be strengthened;the understanding of the significance of the establishment of physical models needs to be strengthened,and the comprehensive understanding of scientific thinking methods is not comprehensive;The general steps are insufficiently understood,some students lack the awareness of inquiry and cannot complete the scientific inquiry experiment process independently;they do not have a substantial understanding of the relationship between STSE,and some students are indifferent to the development of science and technology;the school experimental facilities and equipment are not complete enough to open There are few experimental lessons;teachers do not pay enough attention to experimental teaching;and there is insufficient research on the core literacy of the subject.Secondly,on the basis of following constructivist and humanistic learning theories,and combining the conclusions of the questionnaire,this study is divided into four different categories: the mechanics experiment in the classroom,the demonstration experiment in the classroom mechanics,the student group mechanics experiment,and the autonomous mechanics experiment From the perspective of the type of experiment,a strategy for cultivating the core literacy of students in physics is proposed.Finally,based on the education idea of the core accomplishment of physics subject and the proposed training strategy,the author selects four subjects to carry out the teaching activities of mechanics experiment,which are "gravity and center of gravity "," static friction force "," measuring acceleration of linear motion with uniform speed change" and "free falling body motion ".Then the author analyzes the effect of teaching cases through the form of teaching process observation,interview and students' self-evaluation.Combined with the observation of teaching process,interview and students' self-evaluation table,the design of scientific teaching cases of mechanics experiment is helpful to the cultivation of students' core literacy in physics.The students 'physical concepts,thinking ability,scientific inquiry ability,scientific attitude and sense of responsibility have been improved to a certain extent compared with the time of enrollment,and the obvious effect is the students' thinking ability and scientific inquiry ability.
