Study On Teaching Practice Of Grade Seven And Early Intervention Of The Algebraic Error Prone Points

Grade seven is the key of number and algebra knowledge construction period,the students' mathematical thinking from arithmetic thinking will transition to the algebraic thinking,in the process of formation,errors and hinder the development of thinking.This paper mainly through to the eighth graders targeted questionnaire investigation,and statistical analysis,the result of the investigation and interview and more experienced first-line teachers,sum up the seventh grade number and algebra easy cause of the fault point,and explore the teacher in the seventh grade class and class teaching in terms of number and algebra of early intervention measures,rational analysis can score but it is easy to lose points out the title number and algebra,establish practice project detection feedback after class.Phase phase and the start of the research process,this paper adopts literature method,refer to the related research situation,summed up the seventh grade and the main point of error-prone areas of algebra knowledge types and the current junior middle school mathematics error-prone points early interventions.From the point of the present study,most of early intervention in seventh grade number and algebra easy wrong in some typical types of specific interventions,or is a certain teaching in the classroom on the error-prone points early intervention,not systemically.This thesis mainly makes full use of preview case set easy to wrong topic,ask students to preview before class,question of error-prone points in the class using the student handbook design "trap",let the student fully grasp the corresponding knowledge,finally using the wrong topic set detection after class feedback,thereby reducing the error rate of students in error-prone points,forming a series of intervention measures in advance,improve the early intervention teaching mode.In practice,using action research method,through to the seventh grade students in teaching,for the majority of junior middle school mathematics teachers' seventh grade number and algebra easy wrong point in the early intervention measures of teaching provides a valuable reference.
