Analysis Of The Acquisition Process Of Physical Acceleration Patterns In Middle Schools

Concept teaching is an important part of high school physics teaching.It is also the cornerstone of middle school students' physics study.Some scholars have found that schema theory is the key enlightenment and guidance to the teaching of concept.The concept of acceleration is a very important basic concept during high school physics study.The acquisition of schema in is a complex and long-term development process.The analysis of the acceleration schema acquisition process can provide some suggestions for researchers about how to combine schema theory with teaching research.On the basis of sorting out the main points of Schema Theory,this dissertation explores the acceleration schema and its acquisition process from several aspects in view of the characteristics of the physical schema.Schema is actually a more psychological concept.Its formation mechanism is complex and unpredictable.Therefore,the focus of this study is not limited to the construction of the acceleration schema in a certain class,but focuses more on the process of the student's acquisition of the acceleration schema in stages.First of all,after sorting out the contents of high school education,We found that in addition to the "Acceleration" lesson,"Free Fall Motion","Newton's Second Law","Flat Throwing","Centripetal Acceleration","Movement of Charged Particles in the Electric Field" and "Movement of Charged Particles in a Uniform Magnetic Field" and other teaching contents all play an important role in the establishment and improvement of acceleration schema.Selecting several first-class teacher's teaching records corresponding to these contents for research and analysis,we found that front-line teachers are very concerned about the establishment of the acceleration schema in the "Acceleration" lesson.However,we did not pay enough attention to other teaching content that we believe has a significant role in the subsequent establishment and improvement of the acceleration schema.Secondly,the interviews of individual high school physics teachers on the acceleration schema acquisition process were conducted in conjunction with the analysis of related teaching examples.It was found that the current front-line physics teachers' attention to schema is not high,and they often interpret the schema as a single "figure" which are considered to be only a graphical representation of knowledge,ignoring the importance of the network of knowledge structures-schema.Finally,on the basis of the two,the investigation and analysis of students' acceleration schema acquisition process was carried out.The adapted acceleration schema measurement questionnaire was used to measure the acceleration schema of students in grade one,grade two,and grade three.It was found that the acquisition of the acceleration schema was performed in stages,and the acceleration schema formed by students in different acquisition stages was different.As a teacher,it is necessary to pay attention to the overall acquisition process of the acceleration schema,and adopt different strategies at different stages to promote students to establish or improve the acceleration schema.
