Research On The Teaching Of "Plane Vector Operation" In High School From The Perspective Of Operation Literacy

In the “standard(2017 edition)”,the main performance of mathematics operation as follows: Understanding Operation Object,grasping operation rule,exploring operation thought,analyzing operation result.But the vector is the student in the high school stage new contact has own independent operation system an operation object.The teaching of vector operation starts from the expression of mathematics operation,which can help students have a more systematic understanding of vector operation system and improve their operation literacy.In 2019,a new textbook for Senior High School Mathematics was published,which is based on the standard(2017 edition).Understanding the differences between the two editions of textbooks is important.At the same time,learning about the current teaching situation of vector operation,Using vector operation to solve problems are significant.In this paper,through the existing Mathematical Operation Literacy,Vector Operation Teaching and interpretation of teaching materials are summarized;The paper analyzes the content of “Plane Vector Operation” in two editions of high school mathematics textbooks by text analysis,and analyzes the teaching of teachers by classroom observation.Through the research,the following conclusions are obtained:(1)In the senior high school mathematics new person teaching a edition teaching material arrangement manifests the mathematics operation accomplishment four big displays the material to be more concentrated,in “the operation object understanding”,with the help of the special physical background of vectors and the understanding of the operation object background,the operation rules are defined,expressed and their operation properties and operation laws are explored,in order to improve students to discover operational thinking,in the New Textbook adds more “exploration” and“thinking”,and to enhance students’ understanding of the essence of vector operation.(2)In the teaching of vector operation,the teaching design can be based on the four dimensions of the operation accomplishment,the subject is introduced from“understanding the operation object”,and then through the explanation and students’ inquiry activities,let students master the “operation rules”,and then from the analysis of examples and summary of knowledge,lead students to “explore the operation ideas”,and finally “analyze the operation results”,let students have a deeper understanding of how vector operations are presented.(3)Through the research discovery,at present the Vector Operation Teaching does not have the insufficiency to promote the student mathematics Operation Literacy,according to the new teaching material to the Vector Operation Teaching,first needs to pay attention to the vector operation introduction teaching,and from the related operation of physical background and number,enhance students’ understanding of the“Vector” operation object.Secondly,the basic teaching of vector operation is emphasized.Through the teaching of the essence and significance of projection vector,the students’ mastery of vector operation rules is strengthened.Finally,the application of vector teaching,through the understanding and application of vector collinearity Theorem,make students explore the operation ideas,then realized the perception of vector is a powerful tool to solve mathematical problems.
