The Investigation And Study The Present Situation Of Grade Seven “Integral Expression Of Add And Subtract” Teaching

Grade seven is the transition period of from primary school to junior high school, students in grade seven will do not adapt in study and life. Grade seven is the number of students from the specific operations to the algebraic expression operations of turning point, and the integral expression of add and subtract "is the most important part is also the most basic algebraic expression."Integral expression of add and subtract"not only plays the essential role in the seventh grade math study, but also in the junior middle school mathematics learning plays an indispensable position. If students are not good grasp of the "Integral expression of add and subtract" so will directly influence the mathematics learning of junior middle school students. Therefore as first-line teachers is necessary in grade seven "Integral expression of add and subtract" the investigation of present situation of teaching and learning. In this paper, through the research methods of questionnaire and interview, understand the seventh grade"Integral expression of add and subtract" teaching and learning the status quo, analysis of seventh grade students integral expression of add and subtract the cause of the difficulty, as well as theseventh grade math teacher integral expression of add and subtract the teaching problems and causes, and puts forward seven grade mathematics teaching, especially the integral expression of add and subtract the teaching Suggestions. Hope to enrich the existing research results, this paper also gives the same type schools provide valuable reference.In order to understand seventh grade teaching and learning situation of "integral expression of add and subtract", the author draw lessons from existing content of the questionnaire, and combined with the objective of the study, under the guidance of a mentor completed questionnaire, this research then I had been a teacher of Junior high school in Rong Jiang county Zhai Hao village town 259 students and Six teachers of mathematics in of The class of 2015 grade seven,To study the status quo seventh grade teaching and learning of integral expression of add and subtract.Understanding to the seventh grade students have problems in learning integral expression of add and subtract, such as poor students mathematical foundation; Rational grasp not solid; Not develop good study habits and learning methods; The concept does not understand and will not apply. At the same time, teaching alsohas many problems in Teaching integral expression of add and subtract,such as learning analysis does not reach the designated position; Didn’t pay attention to teaching cohesion; Problems such as improper teaching methods. Finally according to the results of the survey and the authors teaching practice experience, from two aspects of the students’ learning and teachers’ teaching to students and teachers put forward the corresponding suggestion.
