Research On Life-oriented Teaching Of Physical Mechanics In Senior High School Under The Background Of Key Competences

With the all-round reform of education in our country,the aim of education is becoming more and more detailed.The subject key competences have become the subject of teaching,and the “Physical subject key competences” embodies the unique value of the physical subject in cultivating the “Key competences”.“Physics key competences” puts forward four dimensions of requirements for physics teaching goals,forming physics concepts in the knowledge dimension,cultivating scientific thinking in the method dimension and embodying scientific inquiry in the process dimension,the emotional dimension contributes to the attitude and responsibility of science.Before the implementation of the new evaluation system,scores have become almost the only criterion for evaluating the quality of education.How to ensure that teaching is not out of touch with the core quality of the subject,at the same time,it is an important task for physics teachers in senior high school to cultivate students' key competences of discipline and improve students' physics scores.The main research method used in this study is the literature method--through reading relevant literature materials and theoretical books,to understand the research status of “Key competences” and “Life-oriented teaching” at home and abroad,to integrate relevant educational theories and provide theoretical basis for this study.Content analysis-through intensive reading of the 2017 edition of the curriculum standards,accurate understanding of the core quality of physics,familiar with the curriculum structure and content,from which lifeoriented teaching of the course content,understand the spirit of the curriculum standards,implement the educational concept that knowledge of physics comes from life and is applied to life;interpret the Chinese College entrance examination evaluation system;and analyze the2017-20212021 examination questions since the implementation of the curriculum reform,defining the orientation of the college entrance examination.Observation method-observe all the real classroom teaching that may come into contact with,draw lessons from effective teaching strategies,and provide some valuable life-oriented teaching case reference for the author,to ensure that the teaching strategies proposed in the study are more practical.Case method--applying the proposed teaching design model to design teaching cases.This paper analyzes the needs of life-oriented teaching from two angles,analyzes the curriculum standards,teaching materials,the college entrance examination evaluation system and the college entrance examination questions from the national will level,and finds that the new curriculum concept attaches importance to the era of knowledge,pay attention to the relationship between theory and practice,and analyze the needs of teachers and students from the perspective of teaching and learning.The life-oriented teaching strategy based on subject core literacy is put forward.First,pay attention to the creation of the scene.Create life experience situation,inspire thinking;create life problem situation,guide inquiry;create experimental situation,pay attention to practice;2,teaching assisted living.Through language life,teaching means life,teaching methods life,reflect the modern characteristics of lifeoriented teaching.3.We worked to make our tasks more user-friendly.Through designing the task of daily life,guide the students to apply the results of study to explain the phenomenon of daily life,solve the practical problems of production and life,and solve the physics exercises.A life-oriented teaching design model based on the core literacy of the subject is constructed,which is composed of teaching analysis and design teaching events.According to the teaching design model,the author designs the teaching case “The description of the speed changeacceleration”.Then the strategies of this study will be consciously used in teaching practice,monitoring the learning effect.Through practice,it is found that full creation of life situation in classroom teaching is conducive to arousing students' experience knowledge,stimulating their interest in learning and giving full play to their initiative in learning Formula Law into the production of life,so that the context of physical knowledge,not only help students understand the physical knowledge,to solve some of the difficulties in teaching.It can also develop students' modeling ability.Modeling often determines whether the application of physical knowledge to solve the key step of the problem,whether to improve scores,or core literacy training can play a positive role.In the end,I summarize this research,and reflect on the shortcomings,hoping to do better in the future education and teaching work,but also the majority of peer friends criticism.
