Research On Unit Integrity Instruction Design Of Teaching Based On The Core Literacy ——Taking Trigonometric Function As An Example

Core literacy has become the focus of the new round of deepening education reform.The General High School Mathematics Curriculum Standards point out that we should pay attention to the integrity and coherence of teaching content in mathematics teaching,so as to develop students' mathematics core literacy.Unit teaching is a teaching mode guided by the whole idea,which is beneficial for students to learn mathematical knowledge,construct thinking system,master mathematical ability and develop core quality.Therefore,the research of unit teaching design based on core literacy has important theoretical and practical significance.This thesis takes "trigonometric function" as an example and combines "ADDIE" model to study the concrete implementation steps of unit teaching design and the effective teaching mode of developing core literacy.Firstly,through a questionnaire survey of senior high school teachers,t he author understands the current situation of unit teaching,analyzes existing problems and seeks effective teaching measures.Secondly taking "trigonometric function" as the carrier,the author analyzes the unit teaching elements,teaching objectives and teaching processes.Finally,specific cases "the concept of trigonometric functions" and "the nature of sine and cosine functions" are selected for research,analysis and summary.The research conclusions include:(1)Teachers' cognition of unit teaching is not high.(2)Teachers agree with the effectiveness of unit teaching and the promotion of core literacy,but the teaching situation is not optimistic.(3)The traditional teaching mode and resources influence teachers to carry out unit teaching in daily teaching.(4)Through trigonometric function teaching experiment,it is found that the overall learning level and core literacy level of the students in the experimental class are higher.(5)Unit teaching is helpful to enhance the development of underachiever's learning confidence and accomplishment.Based on the research conclusions,this thesis puts forward the following suggestions for teachers' self-development and school construction.(1)Teachers should strengthen their sense of innovation and try different teaching methods to explore effective teaching models for developing mathematics core literacy.(2)Schools should provide teachers with more teaching resources,build platforms for teaching communication,and exert team strength to develop teachers' professional qualities.
