Teaching Research Of Trigonometric Function Review Course From The Perspective Of Mathematical Culture

In recent years,people have paid more attention to "mathematics culture",which reflects that people have a new understanding of the concept of mathematics curriculum,and people have begun to pay attention to the humanistic value contained in mathematics curriculum.Mathematics culture began to enter the vision of the majority of educators and researchers,more and more researchers and educators are engaged in teaching research related to mathematical culture.At the same time,review class plays an important role in high school mathematics teaching,and is an indispensable class type,and students have a certain mathematical knowledge,the essence of mathematics can be more easily understood.Therefore,we take trigonometric function as an example,explore the teaching research of review class from the perspective of mathematical culture,and try to integrate mathematical culture into mathematics classroom,so as to improve students' mathematical literacy.We use questionnaire survey,interview and literature research methods to carry out the research.First of all,through the literature research method,we summarize the related research of mathematical culture,trigonometric function and recitation,make the concept definition,and take constructivism and humanism learning theory as the theoretical basis of integrating mathematical culture into recitation.Secondly,through the questionnaire survey of students and teachers respectively,we find that the current situation of students' trigonometric function learning and review class teaching,and combined with teaching practice,analyze the existing problems.Finally,in view of the problems found in the above survey,four teaching strategies are put forward.Combined with the characteristics of the strategies,specific teaching cases or examples are given,and a teaching case of trigonometric function review course from the perspective of mathematical culture is designed.Through interviews,we know that this review course mode has good classroom effect.Therefore,in the review class teaching design,according to the actual situation of students,reasonable into the content of mathematical culture,highlight the essence of mathematics,so that the review class can play a maximum value.The review class from the perspective of mathematical culture can not only make the classroom more hierarchical,mobilize students' enthusiasm for learning mathematics,but also make students understand knowledge more deeply.Teachers can try to improve students' mathematical literacy comprehensively.
