Practical Research On Improving The Core Literacy Of Mathematical Operations

The General Senior High School Mathematics Curriculum Standard(2017 Edition)(hereinafter referred to as the "Curriculum Standards")was released on the official website of the Ministry of Education at the end of 2017.Operation and mathematical modeling,mathematical operation literacy plays an important role in these six core literacy.In mathematics learning,many topics will eventually be implemented in mathematical operations.Mathematics operations literacy can be said to be an important factor in evaluating students’ core literacy.In the mathematics learning process at all stages,students will have some problems in mathematical operations.For example,some students use a calculation formula to move a rigid set;some students will only have formulas without calculation methods and calculation targets,or the calculation process is particularly cumbersome and the final result is not.correct.Therefore,the "mathematical operation literacy" of the six core literacy is selected for research,the current situation of high school students’ operation level is investigated,and some problems that students may have in mathematical operation are pointed out.Based on these studies,combined with high school mathematics The textbook puts forward teaching suggestions that are conducive to the improvement of mathematical operations for high school students.Literature research,questionnaire survey,case analysis,and teacher interviews were used for investigation and research.Through literature analysis to understand the current research results of mathematical literacy,based on the predecessors and the definition of mathematical literacy in the "Curriculum Standards",the analysis of the presentation of the content of mathematical literacy in textbooks;questionnaire surveys using test papers Method,select series,conic curves,straight lines and equations,circles,etc.as the knowledge carrier for testing students’ mathematical operation literacy.A set of test questions have been compiled to investigate the mathematics operation literacy of high school students and find out the existing problem points.The content of the derivative part is used to analyze the case and design the teaching plan;through teacher interviews,learn about teachers’ views on student operations and put forward teaching suggestions.After the above research,it was found that some high school students ’mathematical literacy level is not high enough.Therefore,teaching suggestions for improving students’ mathematical literacy are proposed: first,we must pay attention to the teaching of basic knowledge;second,we must pay attention to creating problem situations;third,we must pay attention to teaching ideas Method;Fourth,the blackboard that attaches importance to the example questions;Fifth,based on the teaching materials,improve literacy.
