Practical Research On The Falling Of Mathematics Core Literacy In High School Mathematics Teaching

The mathematics literacy system has become the focus of mathematics education researchers and front-line teachers,Which can guide the education to accurately grasp the direction of talent training and the examination evaluation more accurately reflect the requirements of the current talent training.It is worth mentioning that the theoretical research of mathematics core literacy is becoming more and more perfect,but this is worth exploring how to combine it with practical teaching.At the theoretical level,by coming literature,the core literacy of mathematics is multidimensional and unique,which can be taught and evaluated.At the same time,this is important that defining two core concepts of high school mathematics with mathematics core literacy,and constructing the high school mathematics core literacy conceptual framework.At the practical level,the present situation of senior high school mathematics teachers' classroom teaching under the requirement of mathematics core literacy level is investigated by questionnaire.The overall situation is general,which is between partial conformity and relative conformity,and the implementation of weak literacy is logical reasoning.Secondly,we construct the case analysis framework system of mathematics core literacy teaching,collect and sort out the real mathematics teaching cases,carry on the case study,and combine the interview.It is found that there is still a certain distance between the present situation of mathematics teaching in senior high school and the teaching based on mathematics core accomplishment,which is mainly presented in four aspects: lack of deep understanding,emphasis on imbalance,large gap in implementation and less improvement of resources.In view of the above problems,summarizes three teaching views based on mathematics core accomplishment:from knowledge to accomplishment,from attention to learning,from mathematics module to mathematics main line;three kinds of learning views that is in-depth learning,comprehensive learning,subject learning;five teaching principles:grasping the essence of mathematical knowledge,designing and implementing teaching activities,imitating the natural origin of teaching,situational-task-based teaching,enlightening thinking,cooperation and exchange;three major instructional designs theme unit design,depth instructional design and reverse instructional design.Therefore,high school mathematics teaching is regarded as a kind of research,and a complete teaching system based on mathematics core accomplishment is constructed from whole to part.Then it explores the path and method of mathematics core literacy in senior high school mathematics teaching:constructing the training system of mathematics teachers in senior high school;condense the essence of the core concept of mathematics in senior high school;create various situations of mathematics in senior high school;change the concept of mathematics teaching evaluation in senior high school.Finally,a theoretical teaching case is given.
