Research On The Teaching Design Of "simple Equation" Based On The "big Problem" Teaching Mode

The concept of the new curriculum emphasizes that students are the main body of learning,and teachers are the guides and interlocutors in classroom teaching.Classroom teaching is a platform for interaction between teachers and students,promoting knowledge understanding and problem solving.Effective classroom teaching activities can promote the all-round development of students.The use of the "big problem" teaching mode in primary school mathematics classroom teaching,can not only promote the effectiveness of classroom teaching,but also can improve the students' ability to analyze and solve problems,to cultivate students' independent thinking and independent inquiry ability.The use of the "big problem" teaching mode in primary school mathematics classroom teaching,can not only promote the effectiveness of classroom teaching,but also can improve the students' ability to analyze and solve problems,to cultivate students' independent thinking and independent inquiry ability.The teaching mode of "big problem" is a kind of problem teaching mode which is directed at the essence,covers the teaching difficulty,has the high level,and the inquiry is the main problem.In the "big problem" teaching in the classroom teaching,presents "plate type" structure,simplify,layers of depth,open more thinking,more challenging inquiry learning,more rich experience,more conducive to the cultivation of students' mathematical thinking.Research on the teaching design of "simple equation" unit based on the "big problem" teaching model,firstly,through reading and sorting out the "big problem" teaching mode and teaching design of primary school mathematics equation of related literature,and grasp the current situation of "based on the teaching design of primary school mathematics teaching and the equation of big problem"teaching mode.Secondly,in the relevant books,literature,writing based on the "big problem"teaching mode of teaching design on the theoretical basis:the related concept of "problems"teaching mode of the definition and general process,"big problem" teaching mode in primary school mathematics teaching in value and based on the "design for primary school mathematics teaching the big problem" of the basic procedures.Third,through the questionnaire survey,classroom observation and other methods,to analyze the status of the existing knowledge and experience of teachers and classroom teaching situation,to provide the basis for the specific teaching design.Fourth,based on the previous investigation and analysis on the use of"problems" teaching model of the specific design of the "simple equation",mainly including the design of teaching objectives,teaching content design,teaching process design and teaching evaluation design of four parts.Finally,in the basis of the teaching design,classroom teaching of the fifth grade students in the practice of a vocational school,and through the test and questionnaire survey,evaluation and analysis of the teaching effect,the positive effect of the simple equation "teaching practice as well as the main problems.Furthermore,the paper puts forward the reflection on the teaching design of "simple equation" based on the "big problem"teaching mode:problems should be based on the experience of the students,respect the students'main body;pay attention to the teachers and students' deep dialogue,focus on the nature of the problem;promote the effective inquiry process,optimize the cognitive structure.
