Research On The Thoughts Of Primary School Mathematical Model Based On Core Literacy

Core literacy refers to the necessary character and key ability that students should have to meet the needs of lifelong development and social development.How to implement and evaluate in teaching is an important issue to implement core literacy.In order to explore how to implement and evaluate core literacy in primary school mathematics teaching,the PISA tool is used to analyze the survey data to understand the problems.Based on the core literacy improvement design,the model thinking case study is carried out to provide a reference for the primary school to better implement the core literacy.Taking the fifth grade students of a primary school as the research object,the research methods such as literature method,investigation research method and case study method are used.Design a mathematical literacy test questionnaire to investigate the current state of core literacy.The results show that: 1.The ability of students to solve problems in the problem situation is low;2.Students' ability in space concept,reasoning ability,model thinking,and application awareness needs to be improved.According to the existing problems,the model thought as the main core literacy research,the "call","mathematical thinking" teaching design,draw on Yu Ping's mathematical core literacy evaluation framework quantitative analysis of classroom teaching,combined with after-school student interviews,carry out classes Case study practice,the research results show: 1.Model thought and abstraction(symbolic consciousness),reasoning to construct a triangular scaffolding primary school mathematics core literacy system;2.Model thought case has experienced abstraction(pattern recognition),reasoning(mathematicalization),calculation,modeling(knowledge connection),application(analogous reasoning)learning process;3.model thinking,symbolic consciousness,reasoning ability,geometric intuition,application consciousness,mathematical operation,innovation consciousness,etc.have all improved,but in There are no significant changes in the sense of number,space,and data analysis.Finally,the teaching strategy of the elementary school mathematics model is presented.According to the research conclusions,the author proposes the following teaching suggestions: enrich the living materials,cultivate application awareness;respect the learning subject,advocate independent inquiry;perceive mathematics ideas,develop core literacy;cultivate problem-solving strategies,promote habit cultivation;pay attention to methods and methods,improve mathematics thinking.
