Research On The Cultivation Of Mathematical Problem Solving Ability Of High-level In Primary School Based On Project-based Learning

In recent years,the cultivation of students' mathematics problem-solving ability has become a key research objects of academic circles and first-line mathematics teachers.Compulsory education mathematics curriculum standards and mathematics literacy also emphasize the need to cultivate students' sense of application and innovation,and emphasize the mastery of mathematics knowledge and skills to promote the development of students' mathematical problem-solving ability,improve mathematics literacy,and achieve personal development.However,in the context of exam-oriented education,students' mathematical problem-solving ability only stays at the level of solving mathematical problems,and they only focus on problem-solving skills in the process of mathematical problem solving,while ignoring students' mathematical thinking,independent inquiry,and mathematical problems.To solve the importance of ability development,there is a lack of training in students' thinking methods,that is,the primary school mathematics classroom needs to be further developed in students' independent exploration.Project learning is based on the concept of inquiry teaching.On the one hand,project learning can effectively solve the problems in existing classroom teaching due to the particularity of project inquiry,which helps to deepen the cultivation of students' mathematical problem-solving ability;on the other hand,It has an important influence on the long-term development of students' study and life.Therefore,it is very necessary to study the training strategies of students' mathematics problem-solving ability under the project learning mode.This research attempts to study the strategies for cultivating the mathematics problem-solving ability of primary school students from the perspective of project learning concepts.Taking the teachers and students of the fifth and sixth grades of Chongqing A Primary School as the research objects,through classroom observation and interviews,the status quo of project-based learning in the high-level primary school students' math problem-solving ability training was investigated.The survey found that most teachers pay more attention to the integrity of the students' project process and the mastery of mathematical knowledge in the process of project learning,but lack of attention to the students' thinking and inquiry and the improvement of students' mathematical problem-solving ability during the project.According to the current survey,it is found that there are four main problems in cultivating students' mathematics problem-solving ability under the project learning method in the surveyed schools,namely,the low driving force of the project problem situation,the lack of penetration of conjecture and hypothesis in the formulation of the project plan,and the lack of project exploration.The cultivation of the ability to monitor the process of solving mathematical problems,the cultivation of the ability to reflect and evaluate mathematics projects is just a formality.Based on the above problems,this research also explores the main reasons for these problems,that is,the teacher level,the student level,the educational evaluation system in the context of test-oriented education,and the lack of support from the school environment.Finally,based on the above problems and reasons,corresponding training strategies are proposed:(1)Strengthen the driving force of mathematics projects:improve the understanding of the context of mathematics problems;(2)Optimize the project plan: improve mathematical conjecture assumptions;(3)Improve project activities : To monitor the process of solving mathematical problems;(4)Deepen the evaluation of the whole process: Improve the reflection and evaluation of mathematics.
