Research On Unit Teaching Of High School Mechanics Based On Pre-Learning

Pre-learning is a learning based teaching mode of student-based education.The educational philosophy of this model: learning before teaching,doing before learning,knowing before doing,teaching less and learning more,teaching by learning,learning without teaching.Its main purpose is to transform students’ passive learning into active learning and autonomous learning under the new curriculum reform.Stimulate students’ interest in learning,cultivate students’ cooperative learning ability and enhance students’ sense of cooperation,so as to improve students’ autonomous learning and classroom efficiency.By consulting the literature,it is found that there are very few cases of pre-learning on the teaching of physics in senior high school.Therefore,the author uses the opportunity of educational practice to carry out the educational practice of pre-learning.In the field of pedagogy,trying to find the educational method of students’ autonomous learning has always been one of the concerns of educators.Unit teaching based on core literacy has become one of the hotspots of physics teaching reform.Unit teaching emphasizes students’ learning as the main body,so the author has carried out the practice of pre-learning in unit teaching.The implementation of unit teaching in teaching is an important way for students to realize pre learning."How to carry out unit teaching based on pre-learning" and "what is the effect of unit teaching" are the two key issues of this study.In the practice of physics teaching,we use pre-learning to advocate unit teaching.The theoretical and practical part of this paper focuses on prelearning and unit teaching.This paper takes the unit content of Newton’s law of motion,a compulsory course in senior high school physics published by people’s education press,as an example to study how to promote pre-learning in senior high school physics unit teaching.This paper analyzes the research situation at home and abroad by using the literature research method,and expounds the significance and purpose of the subject based on the high school physics curriculum standard,combined with pre-learning and unit teaching.It is supported by student-based education theory,humanistic theory,Bruner’s discovery learning theory and Gestalt learning theory.This paper discusses the definition and relationship of related concepts of pre-learning,unit teaching and subject core literacy.Through the method of questionnaire survey,this paper understands the current situation of students’ pre-learning and mechanics learning in practice schools.Through the interview recording method,this paper understands the current situation of prelearning and unit teaching of teachers in practice schools.The results are used as the research basis for practical teaching.On the basis of collecting literature and data,this paper determines the unit teaching mode based on pre-learning,and expounds the selection of corresponding unit teaching steps.Through the action research method,Taking the unit content of Newton’s law of motion in high school physics as an example,classroom teaching is carried out according to unit teaching,and the new teaching,exercise class and review class were carried out with Newton’s first law as an example.At the same time,the experimental class and the control class are selected as the test objects of students’ midterm examination results,and practical research is carried out.By comparing the unit test results of the experimental class and the control class,as well as the investigation and analysis of students,this paper summarizes the actual effect and existing problems of high school mechanics unit teaching practice based on pre-learning.Through statistical analysis,this paper puts forward teaching suggestions for the conclusions of practical research,and looks forward to the future research.Through the research,this paper mainly draws the following three conclusions: unit teaching guided by pre-learning can promote students’ autonomous learning;Unit teaching based on pre-learning can improve students’ comprehensive ability;Unit teaching based on pre-learning can improve the teaching effect.According to the actual research results,the following teaching suggestions are put forward:encourage students to communicate with each other;Carry out special teaching and training;Pay attention to unit teaching design;Timely reflection and evaluation.
