Research On The Integrated Teaching Of "Trigonometric Function" Unit In Senior High School Under The New Curriculum Standard

In 2014,the Ministry of Education issued the Opinions on Comprehensively Deepening Reform and Implementing the Fundamental Task of Cultivating Virtue and Cultivating People,emphasizing the need to pay attention to integrity in the process of revising curriculum plans and curriculum standards.The "General High School Mathematics Curriculum Standards(2017 Edition)" updates the teaching content,attaches importance to the concept of the subject as the core,makes the course content structured,and clearly puts forward that mathematics teaching should grasp the teaching content as a whole to promote the continuity and phased development of the core literacy of mathematics.The overall teaching of the unit is structured around the theme,which is an important way to achieve the structural change of content,and it is also an important means to implement the core literacy goal.Therefore,this paper focuses on how to carry out the overall teaching of high school mathematics units under the new curriculum standard.Firstly,the research background and current situation of unit overall teaching and trigonometric function teaching are sorted out by literature research method,the concepts of unit,unit overall teaching design and unit overall teaching are defined,and the relevant contents of system theory,"Ub D" theory and constructivist learning theory are sorted out,so as to provide a theoretical basis for the construction of the overall teaching mode of high school mathematics unit with integrated teaching evaluation.Secondly,three basic principles of the overall teaching of high school mathematics units-the principle of wholeness,authenticity and integration of teaching evaluation are proposed,and the overall teaching mode of high school mathematics units with integrated teaching evaluation is constructed,the basic operation process is given,and the opinions of teaching area teachers and researchers and front-line high school mathematics teachers are revised and improved.The basic operation process of the teaching mode is as follows: first,determine the overall teaching content of the unit,that is,analyze the teaching elements,clarify the big concept,divide the basic problems,and construct the big framework of the unit knowledge;Second,the overall teaching objectives of the unit are compiled;Third,the evaluation task of the design unit;Fourth,the overall teaching process of the design unit is to create big scenarios,ask big questions,experience the process of knowledge development,and form big concepts;Fifth,teaching practice and evaluation,reflection,and improvement of teaching design.Finally,according to the overall teaching mode of the unit proposed in this study,the trigonometric function is taken as an example,and a case of the overall teaching design of the unit is given for teachers’ reference.
