The Investigation And Study Of The Teaching Status Of Linear Equation With One Unknown Application Problems In Junior Middle School Mathematics

Equation in one unknown application problems is one of the most important content in junior high school mathematics teaching.The level of application problems of equation in one unknown learning attained directly affects the learning in inequality、application problems of binary system of equations and application problems of quadratic equation.For the teaching of the application of equations,Compulsory education mathematics curriculum standard(2011edition)(Hereinafter referred to as the standard)has emphasized that it is important to teach model thought 、 application of consciousness and innovation consciousness.The standard demands the learning in equations(or binary system of equations)should be pay attention to exploreing,researching and discussion in application problem,And focus on solution and application.Especially,the standard demands students can write out the equation according to the number of specific problems,and can feel that equation is an effective model to describe the quantitative relationship of the real world..This paper is based on the current situation of the research on the application of one-dimensional equations in junior middle school.Combined with literature induction and questionnaire survey,and qualitative and quantitative analysis combined method.From the teacher’s teaching and the student’s study two angles,a study on the teaching status of the applied problems of one-dimensional equations of middle school mathematics is carried out.Design questionnaire,and use SPSS software to analyze the questionnaire.Through a questionnaire,we can get a one-dollar equation and we can do the right thing.By statistical analysis,we find a problem in the course of a one-dimensional equation,and we can sum up a one-dimensional equation for the teaching of the equation and the teaching suggestions.This questionnaire survey is based on the relevant theories of "standard" and "one-dollar equation".This paper analyzes the present situation of teachers’ teaching and the status quo of students’ learning by studying the mathematics teachers of a county in ji ’an county and the seventh grade students in the county.The following conclusions are drawn:(1)There is a lack of way to connect the elementary and middle school equations;(2)Nearly half of the teachers did not know the difference between solving problems and solving problems using column formulas;(3)Students are not interested in using a one-dimensional equation.
