| The physical concept is the basis of a physical system,so the teaching of the physical concept plays an important role in the physical teaching system and is the most concerning problem in front-line teaching.However,our country has been influenced by objective epistemology for a long time and formed the teaching mode of only letting the students do the problem.This kind of teaching mode,which does not pay attention to the understanding of the concept,but only pays attention to the application of the concept,hinders the process of the establishment of the student’s physical concept,and is not conducive to the cultivation of the students’ various abilities,the students lost their confidence and interest in learning physics.The theory of contemporary constructivism is widely accepted in the fields of teaching and psychology,and it is also the theoretical basis of our curriculum reform,however,no strict and concrete principles of teaching design have been formed,and the application of the basic ideas of constructivism in teaching activities is not ideal.Therefore,this paper will combine the two,the rational application of constructivism in the teaching of physical concepts,the concept of students and the ability to build a far-reaching significance.Through lots of literature,the author has a more profound understanding of contemporary constructivism and physical concepts,and by conducting a questionnaire survey of students and interviews with teachers,it is found that the following problems exist in the teaching of physics concepts in middle schools: 1.Students showed insufficient interest,ability and initiative in learning physics concepts.2.Traditional teaching concepts,and rigid teaching methods;3.The school hours are not arranged properly.Based on the above problems,according to the contemporary constructivism theory and the characteristics of the physical concept,the author puts forward the principles of physical concept teaching design based on constructivism.To verify whether the teaching design can help students to learn physics concepts,the author carried out a half-year practice in two classes of the practical school.The content of the experiment is to randomly select two classes the control class and the experimental class.The concept teaching activities of the control class were carried out according to the traditional teaching design,while the experimental class was carried out according to the teaching design based on the contemporary constructivism theory.In this paper,taking the concepts of particle and acceleration as examples,the disadvantages of traditional instructional design and the advantages of instructional design guided by contemporary constructivism are analyzed respectively,and the experimental results were verified by Excel and SPSS.The experimental results show that the instructional design can help students learn physics concepts.At the same time,it can exercise students’ both Operational capability and communicative abilities.Furthermore,it also can improve the ability of students to find,analyze and solve problems,so that we can cultivate their scientific attitude and responsibility. |
