| Mathematics is a subject closely connected with life,in which the purpose of mathematics application is to apply knowledge to real life,and the closeness of knowledge and life is more significant in solving the mathematical application problems.In the process of teaching mathematics in primary school,the knowledge of applied questions takes up a large amount of space.This research is to divide the application questions into more detailed and explore one of the important branches-the score application question.Because of the abstract of scores and the complexity of the algorithm,the application of scores has become a "stumbling block" in mathematics learning of primary school students,and has become an important part of the ability of students to solve problems.The researchers study the complex score application problems of grade 6,which are added,subtractive,multiplication and division,which are more representative,and can systematically explore the factors that affect the problem solving obstacles of grade 6students’ scores application problems,and the suggestions or strategies proposed are more persuasive.This study mainly takes the students of grade 6 of the school where the researcher is practicing as the research object,and uses the methods of literature research,questionnaire survey,test questions and interview survey to explore the obstacles encountered in solving the scores application problems in Grade 6 of primary school.The researchers divide the dimension of questionnaire analysis into students’ Reflection on the process of solving the problem(reasons for the loss of scores,the type of application questions,etc.)and various factors(such as semantic representation,quantity relationship construction,problem solving strategy transfer and calculation operation)to explore the obstacles of solving the problem of score application(such as semantic representation,quantity relationship construction,solution strategy transfer and calculation operation);according to the students’ mastery process of knowledge points of score application questions The difficulty level of test questions is controlled properly.The types of errors and frequency of each problem in the test questions are counted.According to the error types of the test questions,the four obstacles to solve the problem are summarized: semantic representation obstacle,relationship construction obstacle,problem solving strategy selection obstacle and calculation operation obstacle;in addition,the students with different solving level are interviewed to understand the problem solving process in depth Finally,according to the data information provided by questionnaire,test questions and student interviews,the main reasons for the obstacles are: students lack of knowledge and conversion awareness of information in the topic,difficulty in grasping the quantity relationship,insensitive choice and transfer of solving strategies The paper puts forward the corresponding countermeasures and measures: perfecting knowledge system,focusing on language transformation and training,creating appropriate problem situations,improving relationship representation ability,stimulating learning motivation,strengthening strategy training,improving operation skills and cultivating good problem solving habits,etc.,so as to provide teachers with teaching improvement suggestions,so as to improve teaching skills Students’ ability to solve problems and the ability to use knowledge. |
