Research On Teaching Design Of Trigonometric Function Unit Based On Deep Learning

With the continuous deepening of educational reform,the new era has put forward higher quality requirements for cultivating talents.The theory of deep learning leads the current trend of educational development.Unit teaching is an important means to achieve deep learning.Trigonometric functions are challenging for high school students.Therefore,choose trigonometric functions as the research object of unit teaching.By compiling and reading relevant literature on deep learning、unit teaching and trigonometric functions.Learn about the operational process of unit teaching design based on deep learning.Under the theoretical guidance of unit teaching based on deep learning,follow the challenging principle when selecting unit learning topics,and determine that trigonometric functions should be the research object of unit teaching design.After determining the research object,conduct overall analysis of the trigonometric function unit,including the curriculum analysis of the trigonometric function unit、analys is of content and ideological methods、analysis of mathematical core literacy、analysis of the development and connection in senior high school mathematics curriculum、analysis of learning situation and comparative analysis of teaching materials.Based on the overall analysis of trigonometric function unit,the unit theme of this study is condensed:designing problem situations from the perspective of the unit as a whole,constructing trigonometric function model,and achieving the goal of improving mathematical modeling literacy.Based on the theme,refine the teaching objectives of the trigonometric function unit.According to the unit teaching objectives,make an overall plan for the teaching of the trigonometric function unit.Divide the trigonometric function unit into five subunits,namely,the preliminary knowledge unit,the core concept unit,the summary and improvement unit,the mathematical modeling unit,and the trigonometric operation unit Then,conduct a specific learning activity design for each subunit.Finally,the introduction process of the class hour teaching design under the perspective of unit teaching is given,including the arbitrary angles、radian、concept and properties of trigonometric functions(induction formulas、monotonicity)and sine class function y=Asin(ωx+φ).
