Strings Of Questions In Primary Mathematics Teaching Applied Research

"Mathematics Curriculum Standards for Compulsory Education(2011 Edition)" regards "problem solving" as an important content for explaining the overall goal,emphasizing that students can use the mathematical thinking mode to think in the teaching of mathematics,and in the process of thinking,they will discover and raise problems.Ability to analyze problems and solve problems.The problem is the center of thinking.Combining the questions raised by students and the teachers 'preset questions to form a string of questions in a logical relationship from shallow to deep,can effectively mobilize the students' thinking and improve the problem-solving ability.The elementary school stage is a key period for cultivating students' problem consciousness.In question-based teaching,students' problems are used as the starting point for teaching.The students' problem consciousness has been improved to a certain extent.Teachers pay full attention to the development of students.This research was carried out using a combination of qualitative research and quantitative analysis,and specifically adopted a variety of research methods such as literature analysis,questionnaire survey,interview,and experiment.The research mainly includes the following four aspects:First,by combing the existing relevant literature and materials,sorting out the theoretical basis of problem-string teaching,clearly defining the core concepts of "question-string" and "question-string teaching";Second,through questionnaire surveys and interviews to understand teachers' value cognition of elementary school mathematics question string teaching,elementary school mathematics question string teaching situation,question string design ability and reflection of elementary school mathematics question teaching.Teachers have a certain sense of problem teaching in elementary mathematics question string teaching,but their understanding of question string teaching is still insufficient,teachers have a clear bias towards the class and field of question string teaching,the correlation between the problems is not strong,and the students' thinking time is insufficient,the problem awareness of the students needs to be strengthened,and the adaptability of the question string teaching is not strong;Third,combining the current situation of elementary mathematics problem string teaching and the characteristics of elementary mathematics teaching,sort out the types of elementary problem strings,the basis of the problem strings,methods,and principles,and try to construct a model of elementary mathematics problem string teaching.Fourth,in order to test whether the primary school mathematics problem string teaching model is feasible and effective,the experimental class and the control class are selected to carry out teaching respectively.The validity and feasibility of the primary school mathematics problem string teaching model is tested by comparing the experimental group with the control group.Studies have shown that question-based teaching is in line with students' cognitive characteristics,and can help teachers optimize the teaching structure and enhance teaching design capabilities;Teachers 'understanding of problem-based teaching and students' problem awareness need to be strengthened;Question-chain teaching can improve students' ability to find,ask,analyze,and solve problems;Under the mode of primary school mathematics question teaching,students' enthusiasm and achievement for learning have improved.
