The Research On Teaching Design Of New Class Lead-in In Junior High Mathematics

Most of the knowledge in the math teaching of junior high school is embodied in new class.While as the beginning of new class,the leading in of them is a gold key to the new class learning.A great lead-in of new class can connect the old and new knowledge effectively and stimulate the students' studying interest as well.This can make them build the confidence of learning math in the future and also make the bilateral activities of teaching become more effective.The author made a survey of the new class lead-in by using the documentary method,survey method and case analysis method during the investigation of this paper.By looking up the related documents,the author analyzed and studied the basic principles and research results in detail,and also established research methods of new class lead-in.At the same time,the author designed the questionnaires for the front line teachers,which also meet the mental feature and cognitive ability of junior high students.By sorting and analyzing the data,the author has learned about the current situation and reasons caused by it.Besides,the author summarized the common methods of new class lead-in according to the knowledge type.As for the new class lead-in cases,the author went to campus to design the teacher interview and student survey in order to investigate the effect of new class lead-in.The author sorted and concluded the existing problems of current new class lead-in of junior high math,as well as proposing some optimized suggestions for them.In order to gain the exact conclusions,the author made the survey on the basis of real data purposely during the research.The aim is expecting that it will be helpful to all of the teachers.Because of the limit of personal knowledge,energy and other factors,there are still some deficiencies during the survey.Therefore,theoretically and virtually,much more time and energy need to be put in.Besides,the number of teaching cases and interviews selected in this paper also needs to be increased,which will be improved gradually in the following relative research.
