Research On The Teaching Of Trigonometric Function Based On The Core Literacy Of Intuitive Imagination

Trigonometric function is one of the most typical periodic function.It has great effect in describing the periodicity of movement and change,and is closely related to people's life.Trigonometric function is the fertile soil for the cultivation of the core quality of intuitive imagination,it can make students perceive the shape and change of things by means of geometry and intuition,it is conductive to the formation of the thought of the combination of number and shape.In order to adapt to the development of the new era,we should pay attention to trigonometric function teaching research based on the core quality of intuitive imagination.The article first summarizes the research background and significance,a comprehensive review of the existing literature at home and abroad,then,the purpose and method of the research are clarified,then,using the literature analysis method,the relevant mathematics education theory based on the trigonometric function teaching based on intuitive imagination core literacy,then use questionnaire surveys and interviews to investigate high school mathematics teachers and students in City A and City B,understand the status quo of trigonometric function teaching in view of the core competences of intuitive imagination,finally,specific analysis results of the investigation was implemented,according to the existing problems proposed several strategies,and the teaching design of "Induction Formula" was given according to the relevant strategies.Based on the above research,the following conclusions can be drawn:(1)In the teaching process of trigonometry,it is very necessary for students to visualize the core literacy,but the actual implementation of the teaching process of trigonometry is not optimistic.(2)Trigonometric function teaching based on the core literacy of intuitive imagination places a greater demand on teachers' "teaching" : First,teachers must carefully study curriculum standards and update teaching concepts;Second,teachers must master professional knowledge proficiently and grasp the essence of mathematics;Third,teachers should have a deep understanding of education theory and improve teaching ability;Fourth,teachers should attention importance to the use of information technology and promote the integration of information technology and mathematics courses.
