The Study On Mathematical Operation Error Of Junior School Students

Mathematical operations throughout the process of mathematics study, the students’ability of operation directly affects the students’ mathematics learning effect. Junior highschool students in elementary school on the basis of digital computing added the combinationof the formula and graphics geometry solving, as well as the increase of difficulty also makestudents operation error increased.In general, students of operational errors produced is not an accident, it reflects theexistence of the potential factor in the production of all kinds of errors in essence. Therefore,analysis and research on the students’ operation error, should be an important aspect ofmathematics teaching process, and become the breach of the teaching deeply.The author summed up the six types of operational errors based on reading, sorting andanalyzing a large number of literature and the analysis of the student interview record and theteaching practice of three years. The six types of errors are respectively: Informative error,Topic error, Logical error, Thinking errors, Dad habits error and Psychological barriers error.The informative error is divided into: conceptual understanding error, using the error, the lawsof nature to use errors, the application of formula and theorem of error.In the specific classification, the author had list some common instance, and analyzedand researched the causes of these errors. On this basis, put forward to overcome the studentsoperation error of six kinds of teaching strategies, they are:(1) to strengthen the operationprogram understanding;(2) improve the ability of the topic;(3) train thinking ability;(4)develop good operation habit;(5) to eliminate the psychological barrier,(6) to cultivateinterest in learning.For the teaching of the author’s practice, apply the above strategy, summarizes four kindsof designed to prevent and correct operation error of classroom teaching practice, they are:(1)to prevent operation mistakes, be safe.(2) to strengthen the teaching of contrast, timelysummary;(3) strengthening for breakthrough, held the key;(4) organize after-schoolreflection, consolidate the optimization. In this paper, we attempted to find the sources of the errors, based on the study ofstudents’ errors in mathematics learning. Put forward some effective measures andrecommendations, and provide some reference to the effective elementary school mathematicsteaching.
