| The related content of integral expression is the basis of algebra in Middle school,many scholars and teachers have studied it,and get fruitful results.The junior middle school students in Dongxiang cannot express in chinese very well,And they are lack of abstact generalization ability to the same kind of objects,and their learning method is single.So,they are not comfortable for the content of mathematics learning in junior middle school.Related concept of integral expression is the lay content of mathematics in junior middle school.At the same time,students need to break through the first difficult hurdle.In order to explore the difficulties and the reasons for learning related conception of integral expression in Dongxiang national middle school students.This paper choose 200 students as a reascher object from two junior middles schools,one in Dongxiang city and another in Dongxiang countryside.The article surveyed by the making questionnaire and test about four dimensions,from acquisition,understand,characterization to application of related concepts of integral expression.And part of Dongxiang junior middle school mathematics teachers and students were interviewed.Use of Excel and Spss 18.0 statistical software helps to analyze the data,and then try to find out the reasons and difficulties of Dongxiang junior middle school students in learning related concepts of integral expression.Also,put forward some counter measures for improving the learning situation about integral expression of junior middle school students in Dongxiang.As a whole,The situation that the junior middle school students in Dongxiang learn related concepts of integral expression is worring.(1)In obtainment of integal expression,junior middle school students of Dongxiang minority need to improve their analysis ability and abstraction ability.(2)It is not very thorough understanding for junior middle school students of Dongxiang minority to understand the related concepts of intergral expression.(3)It is very chaos for the students to characterize the related concepts of integral expression.(4)The situation that the students use related concepts is not ideal,so their ability to analyze problems,summarize the rules and problem solving ability need to be improved.Influence that junior middle school students of Dongxiang minority learn related concepts of integral expression can be attributed to the following four aspects: students,teachers,textbook and other indirectly influencing factors.For these reasons,put forward the following countermeasures:(1)Be meticulous in teaching design;(2)Attaches great importance to the thought and the nature of the relevant concepts of integral expression;(3)Attaches great importance to the teaching method and more importance to the learning method;(4)Timely evaluation and feedback;(5)To conduct a secondary development of textbooks;(6)Carrying out bilingual teaching dependently. |
