Research On High School Classroom Teaching From The Perspective Of Mathematical Abstraction

<The Curriculum Standards For General High School Mathematics(2017edition)>defines six core qualities of mathematics,among which mathematical abstraction ranks the first and its importance is self-evident.The development of mathematical subject cannot be separated from mathematical abstraction.All mathematical formulas,axioms,laws and viewpoints contain mathematical abstraction.In recent years,the core competence of mathematics has been applied to the classroom teaching of mathematics,which has aroused extensive discussion in the field of mathematics education at home and abroad,and has become one of the hot topics.Let the student's mathematics abstract thought develop in the classroom teaching,the teacher should guide the student to use mathematics abstract thought to carry on the effective study in the concept lesson,and enhances the student's abstract generalization ability in the meantime.This paper builds a research foundation by reading a large number of relevant literatures.After sorting them out,combining with the investigation and education of classroom teaching and teaching practice,the author understands the existing problems in classroom teaching at the present stage and the views of teachers and students on the current teaching situation.Based on relevant teaching theories and actual teaching conditions,this paper proposes relevant teaching strategies for classroom teaching from the perspective of mathematical abstraction.In combination with the actual situation of the practice class,the teaching strategy was introduced into the class analysis of "the concept of sequence".The results of the experiment comparison were presented in the form of students' interviews and after-class tests.In the survey,questionnaires are distributed,teachers and students are interviewed,etc.After sorting and analyzing the data,it is concluded that most teachers understand the importance of mathematical abstraction,but the in-depth study of mathematical abstraction and how to conduct classroom teaching from the perspective of mathematical abstraction still need to be strengthened.Individual teachers tend to pay more attention to students' achievements,and classroom teaching is simplified and formalized in the setting of links,and students lack the process of active participation and independentlearning in class.If students passively accept knowledge,it will make them unable to participate in creative activities,and be ignored by their inner activities.Therefore,the key to how to cultivate students' mathematical abstract literacy lies in teachers' exploration of appropriate teaching methods.Based on the survey results,this paper puts forward the view of carrying out classroom teaching activities from the perspective of mathematical abstraction,which requires teachers to pay attention to the abstract ideas throughout the teaching process.Pay attention to the development of high school students' mathematical language ability and reading comprehension;Through the complete abstract process,master the mathematical abstract "invisible skills".The above strategies are applied to the analysis of class examples and teaching experiments to verify whether certain teaching effects are achieved.In the process of cultivating students' abstract ability,the combination of educational theory and practice has become a new focus in mathematics teaching and research in recent years.With the promotion of the concept of mathematics core literacy,it has a large research space in the future,which is worthy of in-depth research and promotion by mathematical workers.
