Teaching Research On Trigonometric Function Of Senior High School Students From The Perspective Of Deep Learning

Mathematics curriculum reform strives to give full play to the educational function of mathematics and implement the core literacy of mathematics.Thousands of scholars gradually realize the fit relationship between deep learning and mathematics core literacy in the process of studying the difficult problem of "how to implement the core literacy of mathematics".Based on the practical needs of the current education reform,the education and teaching activities and teaching contents of trigonometric function in senior high school should be adjusted accordingly.Combined with the theory of deep learning,this paper aims to implement the core literacy of mathematics and carry out the following teaching research on the trigonometric function unit of senior high school students:Firstly,using the method of literature analysis,this paper combs the relevant research of deep learning and trigonometric function,expounds the relationship between deep learning and core literacy,and defines the connotation and characteristics of mathematics deep learning.Secondly,combined with the ness China questionnaire of deep learning,this paper constructs a questionnaire with six dimensions reflecting the characteristics of deep learning,evaluates the students' understanding level of trigonometric function learning by using test questions and solo classification theory,and preliminarily understands the learning status of trigonometric function of senior high school students.With the help of interview method,we can understand the cognitive level of front-line mathematics teachers on deep learning and the current teaching situation of trigonometric function.Finally,through the research on the curriculum standards and teaching materials of high school trigonometric function units,combined with the practical model of in-depth learning proposed by Professor Guo Hua,this paper constructs the teaching mode of high school students' trigonometric function in-depth learning: the cognitive foundation analysis stage pointing to the cognitive sequence,the teaching goal analysis stage pointing to the high-order thinking,the overall construction stage pointing to the overall connection of the unit,and the self reflection and evaluation stage pointing to the deep representation.The teaching design case and teaching strategy of trigonometric function unit for senior high school students pointing to deep learning are given.
