Application Of “Say Mathematics” In Mathematics Teaching In Senior High School From The Perspective Of Core Literacy

“say mathematics” is a kind of mathematical activity expressed orally through the process of language aiming at some mathematical objects.This paper expounds the concept,content,form of "say mathematics" and its relationship with mathematics core literacy through literature review.The research questions of this paper are as follows: how about the current situation of “say mathematics” ? How to carry out the experimental research of “say mathematics” in senior high school mathematics classroom? What are the reasons behind the current situation of "say mathematics" ?What is the effect of the experiment of “say mathematics”?The main conclusions of this study are as follows:1.The current situation of “say mathematics”At present,“cramming” teaching is still popular in senior high school mathematics classroom.Students dare not “say” or can not “say”.Some teachers and students want to optimize traditional teaching methods,but they dare not innovate for fear of affecting performance.2.Experimental research on “say mathematics”In different types of courses,students are guided to explore the practice of “say mathematics” through “hundred schools of thought,challenge arena,group cooperation” and other ways.In the new teaching,students are mainly interested in learning new knowledge,but afraid of difficulties.Students should step by step when they are guided to “say mathematics”,in the special review class,students are organized to “say” cooperate and explore,and “recreate” knowledge,master new knowledge and new methods;in the examination paper evaluation class,students should be organized to “say” analogy,reflect,promote,and play by "question".The development of the teaching activity of “say mathematics” mainly shows the learning process of “say mathematics knowledge”,“say problem solving”,“say different opinions” and “say harvest” in mathematics class.3.The reasons behind the current situation of “talking about mathematics”Students are used to passive acceptance,afraid of teachers,dare not “say”;pressure of entering school,fear of improper methods leading to the decline of students' performance;mathematics classroom teaching is generally “unilateral teaching”,students are not used to questioning and cooperation;less exchange of emotional attitude and values,teachers pay less attention to the cultivation and promotion of mathematics core literacy.4.Experimental effect of “say mathematics”“Talking about mathematics” activity improves students' interest in learning mathematics,enhances students' learning autonomy and query level,cultivates and improves students' core quality of mathematics,improves students' learning achievements,and enhances teachers' and students' feelings.Suggestions for the teaching of “say mathematics” in Senior High School: to find out “why to say”,“what to say”,“how to say”,“how to evaluate to say”.
