Research On Teaching Of Procedural Knowledge In Junior Middle School Physics

The knowledge of physical procedures is a kind of knowledge that is based on the knowledge of the subject area and is committed to solving physical problems.Along with the proposal of physical core literacy,cultivating students ’physics subject abilities has become the subject of physics teaching,and the core literacy of physics has explained how to develop students’ key abilities.And the teaching of physics procedural knowledge is one of the effective ways to promote the improvement of students’ key abilities in physics.Therefore,the teaching of procedural knowledge of physics is particularly important.The purpose of this research is to enrich the educational theories of physics teachers,and at the same time to provide teachers with a teaching foundation of physical process knowledge.It mainly consists of three parts.Firstly,the relevant literature at home and abroad was organized by the literature method,and the procedural knowledge in "Shanghai Scientific & Technical Publishers" physics textbook at the compulsory education stage was taken as the research object,and it was systematically sorted and classified.At the same time,the author finds that the physics procedural knowledge of junior high school appears relatively frequently in mechanics,electricity,and optics by combing the textbooks.Secondly,through the questionnaire method and interview method,students and teachers were investigated about physical procedural knowledge,to understand the status and difficulties of teaching physical procedural knowledge.The survey draws the following conclusions:(1)the junior high school physics teachers do not have a high level of knowledge and understanding of educational psychology content and procedural knowledge concepts;(2)both teachers and students have a positive attitude towards physical experiments;(3)teachers pay more attention to the training of the transformation of physical procedural knowledge,and students focus more on the learning of the transformation.(4)there are differences between students of different genders at different stages of physical procedural knowledge learning.Finally,basis on the above research,the author uses the existing procedural knowledge teaching model and the characteristics of the physics discipline to initially construct a physical procedural knowledge stage teaching model and proposes corresponding teaching strategies.To enable physics teachers to better understand and apply the physical procedural knowledge stage teaching model and teaching strategies,the author has designed three physical procedural knowledge teaching cases.In these cases,the teaching design ideas of physical procedural knowledge and the specific process of the teacher and student in the same model are explained in detail,and the teaching process corresponding to the teaching model is presented.
