Strategies For Cultivating Motion Concept In The Teaching Of Physical Mechanics In Senior Middle School

The rapid development of society requires contemporary students to have higher skills and literacy.After the "Opinions on Comprehensively Deepening the Curriculum Reform and Implementing the Fundamental Tasks of Strengthening Morality","Core Literacy" has become a hot topic that has received much attention from the education community.The domestic education community has also ushered in a wave of discussion and research on core literacy and core literacy of various disciplines.In the latest high school physics curriculum standard(2017 edition)promulgated by the Ministry of Education,the emphasis on subject curriculum standards emphasizes the core literacy of the discipline,and the first point of the basic concept is to embody the essence of physics and cultivate students' physical core literacy.The concept of physics is at the forefront of the core literacy of physics,and it is the foundation and core of the core literacy of physics.The concept of movement is also the most common and basic concept in physics,and it has its unique meaning.However,with the current physics classroom teaching,most front-line teachers intend to cultivate students' core literacy in teaching.Among them,teachers pay attention to students' scientific thinking and scientific inquiry,while physical concepts are often ignored and schools There is insufficient understanding and action to cultivate students' physical concepts.First,the questionnaire survey method is used to investigate and analyze the current situation of the physical concept of high school physical mechanics.The survey results show that the following problems exist in the current first-line high school physics teaching in cultivating students' motion concept:(1)Teachers Basically,I have a certain degree of understanding of the concept of physics and motion,but the understanding is not comprehensive enough,and the understanding is not deep enough.(2)Teachers generally recognize the importance of the development of the concept of motion to the development of students,but the classroom practice of teachers in the development of motion concept is not ideal,the training method issingle,and the learning effect of students is not satisfactory.(3)Students currently have a low level of motion.Secondly,using text analysis method,based on the characteristics of teaching materials and motion concept,the motion concept of high school physical mechanics is divided into three categories according to the concept of movement description,the concept of movement form and the concept of movement law,and combined with the2017 new curriculum standard and The content of the mechanics part of the high school physics textbook,the concept of the concept in the textbook(that is,the concept behind the specific knowledge)is extracted and elaborated one by one.Finally,combined with the results of questionnaire survey,textbook analysis results and their own practical experience,four teaching suggestions are proposed:(1)clarify the original concept,stimulate cognitive conflicts(2)break through the framework of teaching materials,build knowledge network(3)strengthen concept teaching,promote Concept formation(4)Experience the experience and realize the internalization of ideas.The above four suggestions are refined and combined with the actual application in teaching practice to form a teaching case of three motion concept training.
