Research On The Evaluation Of Trigonometric Function Test Questions In The New College Entrance Examination From The Perspective Of Core Literacy

The mathematics curriculum standard for senior high school(2020 edition)clearly points out that mathematics core literacy is the centralized embodiment of mathematics curriculum goal,and the development of students’ core literacy is the main line of senior high school curriculum education and teaching,since it was put forward,the core literacy,which embodies the value of educating people,has become the focus of educational research.Another hot topic of recent research is China’s national college entrance examination evaluation system,released by the Ministry of Education in 2019,which explicitly mentions the integration of core competencies into the college entrance examination,and its release points the way for the new college entrance evaluation.As the key content of senior high school function,trigonometric function has always been widely concerned by educators,so this paper bases on the above three points to evaluate the new college entrance examination trigonometric function test from the perspective of core literacy,this problem combines three research hotspots,whether it is for the evaluation of core literacy,the new college entrance examination of trigonometric function preparation,or the teaching and learning of trigonometric function are of great significance.Based on the three-year trigonometric function test in the new college entrance examination from 2020 to 2022,this paper constructs the core literacy evaluation framework for trigonometric function test by using the methods of Literature Analysis and questionnaire survey,and according to the evaluation framework for the three-year trigonometric function test questions coding,according to coding statistical data,from the angle of quantity and quality,this paper analyzes the core literacy of 12 sets of trigonometric function test questions in college entrance examination paper as a whole,horizontally and vertically,and finally obtains the examination rule of trigonometric function test questions in the new college entrance examination paper,according to the law of inspection to draw relevant conclusions:The overall characteristics of trigonometric function test questions in college entrance examination: the overall examination of the new college entrance examination highlights the basic features of the trigonometric function test questions,the literacy test is mainly based on logical reasoning and operation,and the logical reasoning literacy test is increasing year by year,while the mathematical operation literacy is decreasing year by year;The examination level of literacy focuses on level one and level two,the situation of examination questions is set conventionally,the pure mathematics background is the carrier of questions,and the transfer of knowledge understanding is the main examination way,the examination of core literacy is extremely unbalanced,the overall examination of modeling literacy is too little,the depth of examination questions is not enough.The conclusion of the cross-sectional analysis of the triangulation questions in the college entrance examination: there is no obvious difference in the examination of the literacy level in the same year,the examination questions are no longer based on the“Elimination”thought system,but on the premise of the students’ thinking development,with the advance of the new college entrance examination,every liberal education has begun to focus on the integration of knowledge,which is clearly reflected in innovative and open examination,mathematical expression has been integrated into the process of problem-solving,and the rigorous characteristics of mathematical subjects have been emphasized.The proportion of operational literacy examination is reduced,and the computational thinking with procedural characteristics is gradually revealed,highlighting the characteristics of the times.longitudinal analysis of trigonometric function test questions in college entrance examination.Conclusion: the examination requirements of core literacy of trigonometric function have been improved and the examination of literacy tends to be reasonable,and all the papers have made different adjustments to the direction of the new college entrance examination The proportion and level of the new college entrance examination(NMET)paper I have increased obviously,highlighting the requirements of the“Four wings” of the NMET The whole examination level of the first paper tends to be balanced,and the change of the examination reflects the thought of “ Attaching importance to logic and weakening calculation”,step by step towards the direction of the new college entrance examination.Analyzing the new direction of the triangle function of the college entrance examination from the core literacy of the examination questions:Increasing the proportion of triangular function core literacy examination,improve the level of literacy examination;We should create innovative situations,follow the social hot spots closely,combine the characteristics of trigonometric functions to explore the setting of innovative and open questions,pay attention to the setting of cross-disciplinary questions,and pay attention to the knowledge fusion of trigonometric functions with mathematical modeling and data analysis,improve the comprehensive awareness of knowledge;Paying attention to the essence of trigonometric function knowledge,taking the thinking method in the learning process of trigonometric function as the direction of examination,weakening the proportion of operations,strengthening the thinking of calculation,paying attention to the examination of thinking and logic,at the same time,we should pay attention to the rigor of thinking and the variety and accuracy of expression.According to the research conclusion,the author puts forward some teaching suggestions: To create various situations,to stress the development of literacy;To optimize the operation methods,to cultivate the computational thinking;To pay attention to the fusion of knowledge,to permeate the synthesis of teaching;To stress the essence of knowledge,to pay attention to the training of thinking;To the expression of reflection,effective evaluation;To optimize the cognitive structure and form a knowledge system.
