To Study The Elimination Strategies Of Students' Geometric Learning Disabilities In Rural Junior High School

Enter junior high school mathematics learning stage,students will be exposed to more knowledge of plane geometry,compared with the primary school time learning algebra,students will enter a new field,the learning object forward from "number" to the "shape".Then research methods will also be a big shift,junior middle school plane geometry learning on students' abstract thinking will be more demanding,mainly students of "reasoning",and elementary algebra learning more predominantly "operation".Faced with such changes,many students find it difficult and daunting.The change of learning object,the change of learning method will eventually be changed in the form of homework.Geometry problem by the expression "number and its operation" to describe the shape and position relationship,language more accurate,concise,rigorous,the students practical ability of language expression.Teaching experience,along with the urban elite group of running a school,students enrollment expansion amount is bigger and bigger,a little bit good economic conditions in rural households,student achievement of a little bit stronger basically choose to go out,so that result in the countryside junior middle school students quality gradually reduce,increasing the proportion of the poor student.From the experience of teaching,it is found that with the increase of geometry in the mathematics teaching materials of junior high school,some students with a slightly lower base have less and less interest in mathematics,and the students are becoming more and more polarized.In many concepts,theorems and basic facts,middle school students begin to lose their orientation and begin to be afraid.Some students are completely puzzled by the geometric proofs.They don't know what to do with this step,and what step should be taken to solve the problem.There are also great difficulties in the transformation of graphic language and text language and symbolic language.Students often use non-logical methods instead of deductive reasoning in deductive reasoning that is derived from premises.Junior high school students do geometry problems,if theyencounter the need to do the auxiliary line,then they will feel overwhelmed.This situation shows that they are only in the simple imitation stage when dealing with "geometric problems" and do not really form a problem consciousness.In the teaching practice and school-level communication,it is found that the obstacle of students in the rural middle school is more obvious in the geometric learning.This phenomenon let me worry for many years,from teaching in rural junior high school,I think,if we don't go to pay attention to the junior middle school geometry learning,then will seriously hinder the rural students of the junior high school stage of learning mathematics,but also would seriously hinder them to focus on high school study.I want to study in the geometry to the countryside junior middle school students the causes of the formation of barriers from the geometric characteristics of knowledge,teachers,students explore the three aspects,through carding a large number of literature material,questionnaire survey results of students is analyzed,combined with their understanding and comprehension in the teaching practice,Suggestions are given at the students mathematical thinking level.This will solve the perplexity in the student's geometry to some extent,help the teachers of the rural schools clearly grasp the crux of the problem,and then take medicine to improve the teaching quality.
