Research On Teaching Strategies Of Middle School Students' Experience Construction Of Basic Mathematics Activities

Exploring the teaching strategies of junior high school students' experience construction in basic mathematics activities is of strong theoretical and practical significance,which is also the need of the new curriculum reform.It is conducive to the implementation of the "four basics and four abilities",the cultivation of students' core mathematical qualities such as mathematical abstraction,logical reasoning and the cultivation of students' innovation ability.Through literature research,it can be found that researchers at home and abroad attach great importance to theory rather than practice,and it is difficult to define the connotation of mathematical activity experience.Therefore,so far no consensus has reached on this issue.This subject mainly employs the literature research,the investigation research,the experience-summary,the case study,the action research and so on.Four years has been used to further clarify the connotation,the dimension division and the level appraisal system of students' experience in basic mathematics activities.It investigates into the current situation of junior high school students' accumulation of experience in basic mathematics activities and the situation of classroom teaching,exploring the classroom teaching mode,classroom teaching principles and evaluation mechanism.The author selects the teaching content of typical value from the two parts of the number and algebra,graphics and geometry in the mathematics curriculum of junior high school,and carries out practical research from the three main class types:new concept course,nature course and application course.In addition,the author puts forward the teaching strategies of junior high school students' construction experience in basic mathematics activities from six dimensions:observing,inducting conjecture,expressing,verifying or proving,migrating Lenovo's use,and reflecting.The main conclusions of this subject are as follows.Firstly,it clarifies the problems existed in the current teaching strategies for junior high school students' experience construction in basic mathematics activities.On the subject of students,it's manifested in the lack of law,less thinking,losing rules,and losing interest.In the teaching of teachers,it's reflected in the lack of research,less creation,losing face,inactivation.Secondly,it deepens the recognition of experience in basic mathematical activities.Experience in basic mathematical activities refers to the nonaxiomatic cognition,experience,ability,thinking pattern for objective property or law of an individual obtained from a mathematical activity(observation,operation,association,inductive guessing,expression,verification or proof,migration analog application,reflection and construction,etc.).The experience process of experience in basic mathematics activities is the process of mathematics learning,that is,the "six studies" process of self-study,mutual learning,exhibition,guidance,extension and end learning.Thirdly,it uses the five theories of structure theory,process theory,methodology,approach theory and evaluation theory,constructing the "five-dimensional" integration strategy for the study of the teaching strategies of junior high school students' experience construction in basic mathematics activities.Besides,it constructs the "six-dimensional"structural theory strategy:the experience of observation,operation and association,induction conjecture,expression,verification or proof,migration,analogy and application,and reflection and construction,and the "six-study" process theory strategy,they are:Self-study(operational,observation and association),Mutual learning(inductive conjecture),Exhibition(expression),Guidance(Verification or proof),Extension(migration and analogy),Conclusion(Reflection and construction).In the process of mathematics activities and situational teaching,constructing mathematical,meaningful "five construction principles" methodology strategy of junior high school students' basic activity experience in mathematics,and approach strategy of "three types of courses" integration including revision-based courses,theming-based curriculum and personalized practice courses.Also it constructs the "three-level" evaluation theory strategy of sensual and intuitive,rational and intuitive,and intuitive thinking.This forms the "six-dimensional","six-study","five-construction","three-class curriculum" and "three-level"comprehensive construction strategies for junior high school students' basic activities experience in mathematics.The "five-dimensional" integration strategy is self-contained,with distinctive features and innovation.At the same time,in the course of the research,the Junior Middle School Students'Mathematical Compositions was compiled,and the Junior High School Students'Mathematical Compositions was developed.
