Research On Cultivating The Mathematical Subject Core Literacy Of Solid Geometry In Senior High School

In the 21 st century,in order to adapt to the global social revolution and promote the development of human civilization,people from many countries are constantly exploring the new teaching models.A new educational concept,subject core literacy,is born with the trend.Based on studying the international definition of core literacy,this paper is about the related concepts and the research status of core literacy of mathematics in senior high school in China.At the same time,the author analyzes the situation of cultivating the mathematics subject core literacy in practical teaching from the following three aspects: the curriculum content and structure,the teaching design and process,and teaching evaluation.To know the situation of cultivating the mathematical subject core literacy clearly,the author did research on cultivating the mathematics subject core literacy of solid geometry in senior high school by taking the relevant teachers and students in the author's school as research objects,using the research methods,such as observation,interview,questionnaire survey and so on.Combined with the teaching records,interviewing the teachers and students,comparison of assignments,verification of the exercises,the author analyzes the excellent teaching cases of solid geometry from the following six perspectives:(1)mathematical abstraction,(2)logical thinking,(3)mathematical modeling,(4)mathematical calculation,(5)direct imagination,(6)data analysis.Summarize the key points of the effective cultivation of mathematical core literacy of solid geometry.At the same time,the author analyzes the existing questions and the causes of cultivating the mathematical core literacy by studying the analysis of the data of the questionnaire and the questions are as follows:(1)the core literacytraining status does not match with the recognition degree;(2)the core literacy training status is significantly affected by the teacher's age;(3)there is a contradiction between the core literacy training status and the teacher's professional title;(4)Other factors affect the effectiveness of core literacy training;(5)students' own situation affects the cultivation of core literacy.As for the questions mentioned above,the author gives the following suggestions to promote the cultivation and the development of mathematics in solid geometry:(1)teachers should continuously improve their personal comprehensive abilities;(2)The reasonable evaluation system and reward mechanism should be established;(3)The guarantee function of school should be strengthened.The suggestions are aimed to cultivating the mathematical subject core literacy in teaching better and help to carry out a new round of teaching reform smoothly with the goal of cultivating moral education.
