Effectively Carry Out Case Studies Of Small-class Junior High School Mathematics Activity Teaching

The active teaching of mathematics in junior high school is carried out effectively on the hot land of small class,which coincides with the requirements of the new curriculum reform.This article tries to find some effective teaching methods of mathematics activity in junior middle school by studying the theory of mathematics activity teaching in small class environment and the actual questionnaire survey to students,and sums up the experience on the basis of each case analysis.It is really feasible and effective to carry out small class mathematics activity teaching.The Mathematics Curriculum Standard for compulsory Education(2011 Edition)adds "double basis" to "four bases",which urges teachers to fully understand the connotation of "foundation" in mathematics learning,pay attention to classroom efficiency,and guide first-line teachers to carry out mathematics teaching effectively.Guide students to think independently,cooperate and communicate,and gain basic experience in mathematics activities.The emergence of any new thing has its inevitability.At the same time,there must be areas for improvement.Over the past many years,there have been achievements and problems in the implementation of small classes.The key is that the change of environment affects the change of teachers' teaching ideas and teaching methods.The first chapter of this paper discusses the necessity and feasibility of effective teaching case analysis of mathematics activities in small classes from the analysis of the new curriculum standards and the reality of junior middle school students,and compares the characteristics and classroom forms of junior high school knowledge with the difference between primary school and junior high school.Analyze the problems one by one.On the basis of analyzing and studying psychology and pedagogy,this paper draws lessons from others' research results,finds out the theoretical basis for effective teaching of mathematics activities in small class junior high school,and summarizes its own advantages: small class size,loose teaching environment.The harmonious relationship between teachers and students reflects these advantages in classroom teaching,which is conducive to teachers' teaching according to their aptitude,to the interactive exchange between teachers and students,and to the active development of students.Compared with the traditional large class size,it is different in teaching process and teaching result.According to the author's experience and curriculum,this paper lists four common types of mathematics activity teaching in small class junior middle school: hands-on operation,reasoning and deduction,outdoor practice,and so on.In the analysis,we found that there are many factors affecting the teaching of mathematics activities in small classes in junior high schools.There are students,teachers,and school hardware and software.But the classroom is the main position for students to develop and teachers to show.Therefore,the main factors that affect the effective teaching of mathematics activities in small classes are the purpose of the activities,the participation of the activities,the guidance of the teachers and so on.How these influencing factors are highlighted in the small class environment,the author conducted a questionnaire to the students,from the purpose of the activity,the participation of the activity,the effect of the activity,The four dimensions of the teacher's guidance investigated the small class size and the large class size,and found the relationship between these factors and the degree of influence by comparing the data.The fourth chapter,according to the author's experience,through several specific cases,analyzes the effective teaching methods of small class junior high school mathematics activities.According to the results of the investigation and the types of summary,< unfolding and folding 1 > show hands-on experiment activities mainly by means of learning plan to carry out students' mathematical activities,< making of puzzle boards > embodying logical reasoning activities with the help of hierarchical teaching so that each student can be taught.Different activities experience,"using the similar triangle height" field operation activities with the help of group cooperation to make the activities more effective,< Statistical chart selection 1 > is the application of modern information technology activities with the help of thinking mapping to make students feel.By the information age breath.Each case has its own unique focus,but it is an effective way of teaching small class mathematics activities,which presents some classroom practice and dialogue,and some application forms,hoping to provide a critical handle for everyone.Better promote our classroom teaching,to help students have a comprehensive and personalized development.At last,this paper abstracts the common characteristics and summarizes the measures and methods of effective teaching of mathematics activities in small classes in junior high school from the following aspects: the choice of activities,the design of activities,the implementation of activities,the evaluation and reflection of activities,and the detection of activities.At the same time,we also hope to carry out more in-depth research and practice.
