The Exploration And Practice Of Self-made Teaching Aids In Junior Middle School Physical Mechanics Teaching

The "Compulsory Education Physics Curriculum Standards(2022)" mentions that "compulsory education physics curriculum is a natural science curriculum based on experiments",which clarifies the importance of experiments in physics teaching.However,there are some problems such as lack of experimental teaching aids and old experimental equipment in compulsory education rural schools,which leads to the unsatisfactory effect of demonstration experiments in some rural schools.Through the self-made teaching aids experiment teaching,it can make up for the lack of learning experimental equipment to some extent.It will also help students understand physics from various aspects,feel the charm of physics,improve their interest in physics learning,and truly implement the physics education concept of "from life to physics,from physics to society".Based on the humanistic learning theory,constructivism learning theory and Dewey’s educational thought,this paper analyzes the data of student questionnaire and teacher interview.According to the principles and steps of self-made teaching aids,12 self-made teaching aids are made,and 9 of them are selected for teaching design and practice.The details are as follows:First of all,a total of 653 students in six classes of Grade 8 and Grade 9 in the school where the author teaches were surveyed by questionnaire,and a total of 12 physics teachers in rural schools were interviewed.The results show that:(1)it is serious that teachers use "watching experiments video" instead of "demonstrating experiments" in physics teaching;(2)Students have high expectations for teachers’ demonstration experiments;(3)Both teachers and students agree that making homemade teaching aids with life-oriented materials can enhance students’ interest in physics learning and contribute to the implementation of core physics literacy.According to the conclusions of the above interviews,the principles and design steps of self-made teaching aids were determined,and the self-made teaching aids were explored.Combined with the actual physics classroom teaching situation,this paper made 15 teaching aids in three teaching links,namely "classroom introduction link","knowledge new teaching link" and "after-class exploration link",and selected 8 of them to write experimental design for teaching practice.The experimental class and control class selected are the author’s class,and there is no significant difference between the students in the class.On this basis,controlled experiment teaching will be carried out for one semester.After a semester of experimental teaching,test papers and questionnaire survey were conducted on students,and it was found that the effect of self-made teaching aids experimental teaching was mainly manifested in the following aspects:(1)The physical performance of students in the experimental class was higher than that in the control class,and the physical performance of the two classes was different after independent sample T test.(2)Students in the experimental class have higher interest in physics,better understanding of physics,and better understanding of "physics and life" than those in the control class.
