Research On The Application Of "Problem String" In Junior Middle School Mathematics Teaching Design

Mathematical concept is the starting point of math learning,is the basis of the composition theorem,rule and formula,is to learn the premise of other mathematical knowledge.For maths,the concept of mathematics is like a foundation,the source of water.What kind of teaching methods should be adopted in the junior middle school mathematics concept class to make the mathematics concept class to achieve its proper meaning,it has been a problem for every educator.In order to improve the effectiveness of mathematics teaching in junior middle school,this paper puts forward the idea of applying "problem string" to junior middle school mathematics concept teaching design.Therefore,this paper uses the method of literature analysis,find the "problem string" mathematical concepts and teaching-related research,and sorting and analysis,thus establishing the research ideas and theoretical framework of this paper;secondly,according to the above analysis of the "problem string" to analyze the connotation,established the "problem string" in the junior middle school mathematics concept teaching design application significance;based on the above analysis,the paper establishes the basic principles of "problem string" in junior high school mathematics concept teaching design;once again,according to the corresponding design principles,selecting two teaching content for teaching design;finally,through the analysis of the two teaching design,drawing the conclusion of this paper.Through the analysis and research on the design of the concept of "problem string" in junior middle school mathematics concept teaching,we can draw the following conclusions: first,the use of "problem string" for junior high school mathematics concept teaching design,have the following advantages: can improve the enthusiasm of students;fully embodies the "students as the main body" of the new curriculum requirements,improve students' ability to analyze problems and solve problems,strengthen the generation of concepts,help students understand the concept of mathematics;second,this paper puts forward the design principle of "problem string" in the teaching of mathematics concept: attention to the introduction of the concept,play the "problem string" cited function;reveal the formation of the concept of the process,play a "problem string" inspired role;clarify the concept of knowledge,play a "problem string" integration effect.The study is mainly based on theory,practice is insufficient,therefore,in the follow-up study can be specifically applied to practice,to test the effect of teaching with practice.I believe that this "problem-driven" problem "string" class will be recognized by everyone,"problem string" will also become a mature teaching model.
