Strategic Research On Improving The Problem Solving Ability Of Junior Middle School Students Under Mathematical Core Literacy

Mathematical problem solving is one of the hot issues studied by scholars at home and abroad.The research related to the solution of mathematical problems is quite rich,but most of the research is only from the perspective of mathematical problem solving,including its connotation,influencing factors,research on improving countermeasures.At present,the social economy is constantly developing.Education is not limited to teaching students' knowledge and skills.It is even more difficult to ignore the improvement of literacy,mathematical core literacy came into being.Mathematical core literacy advocates students to explore independently,attaches importance to imparting mathematical ideas,encourages learners to cooperate and communicate,and pays attention to the cultivation and formation process of students' abilities.However,at present,Chinese middle school students have weak problem awareness,weak reflective consciousness and poor thinking ability in mathematics learning.It is very important to explore the teaching strategies to improve problem solving ability in the perspective of mathematical core literacy to improve the comprehensive ability of junior high school students.significance.The first chapter describes the research content and significance,research methods,and clarifies the basic framework.The second chapter understands the literature and research results at home and abroad,and takes this as the foothold and direction of the research.The third chapter takes 304 junior middle school students and 107 in-service teachers as the survey objects,and analyzes the current situation of mathematics problem solving in junior middle school by issuing questionnaires.It is expected that the ability to solve junior middle school students' problems can be improved in the context of quality training.Provide countermeasures for reference.The fourth and fifth chapters propose eleven relevant teaching strategies and related teaching design,aiming at improving students' awareness of the questions and reflections,in order to provide assistance for the subsequent education work.Mainly draw the following conclusions and teaching strategies:1.In the whole process of problem solving,junior middle school students have low levelof ability mainly in the process of drafting plans and reviewing and reflecting.From the perspective of mathematical core literacy,students are more prone to errors when dealing with mathematical abstractions,logical reasoning,mathematical operations and other related topics.2.Under the perspective of mathematical core literacy,teachers must re-master the connotation of mathematics curriculum,guide students to examine mathematical core literacy,and establish a correct view of learning.3.Teachers should actively carry out inquiry activities in teaching,pay attention to the penetration of mathematics culture,encourage students to divergent thinking,avoid single problem-solving strategies,cultivate students' ability of mathematical representation transformation and problem understanding,and develop their mathematical core literacy.4.Teachers should adopt a variety of teaching evaluation methods,not only paying attention to the evaluation of results,but also paying attention to process evaluation.In teaching design,teachers should optimize design ideas and pay attention to infiltrating mathematics.After class,teachers should pay attention to guiding students to improve the management of wrong questions,formulate mind maps,learn from the wrong questions,review knowledge from maps,and cultivate students' review and reflection habits.
