Investigation And Study On The Ability Of Target Selective Coupling In The Geometric Proof Of Junior High School Students

In 2000 the Mathematical Teachers Association of the United States first proposed the ability of mathematical coupling ability.It is helpful for students to use relevant information.The target of selective bonding capability is proposed based on the diversity and complexity of mathematical coupling ability,focusing on the problem of goal oriented selective coupling.Based on the analysis of mathematics coupling ability and target of selective bonding capability related literature,and combined with the characteristics of geometric proof,the concept of the ability of target selective connection in geometric proof of junior middle school students is put forward.It means that junior middle school students can be guided by problem goals and linked to the learning of mathematics related concepts,propositions and methods etc,actively making proper and reasonable screening and processing.It is a kind of geometric proof to solve mathematical problem solving ability for specific tasks,including selection,connection processing cognitive components of recombine geometric module in the study of knowledge,including the process of planning to target selective link their monitoring and regulation of meta-cognitive components.Based on the geometric proof in the selectivity of target bonding capability investigation of junior middle school students,to understand the geometry proof ability of junior middle school students join selectivity of target,and target selective connection to effect of geometric proof of the junior high school students,and puts forward some countermeasures to cultivate the students in geometry proof ability of target selective coupling.The sequences of the research are as follows.First,determine the direction of research.First of all,this paper analyzes the relevant literature of the selective connection of the target,obtains the relevant research results,and determines the content of the study.Second,the construction of the relevant theory.According to the theory of psychology and mathematical education psychology,the theoretical basis of the selective binding ability of geometry proof is constructed.Third,design investigation and implementation.The survey was carried out in the form of a questionnaire and a combination of geometric tests.Fourth,draw the conclusion.According to the survey results,the present situation and the level of selectivity of target joint ability in geometry proof in the junior middle school students,and to solve the geometric proof problem,and make a reflection,put forward necessity of training target in the selective connection geometry proof ability.Fifth,the training strategies are put forward.The main conclusions of this study are as follows: first,junior high school students in the geometric proof of the target selective connection consciousness performance in the middle,two large differences.Second,there is a significant difference between the target and the target in the target selectivity,which is mainly reflected in the female students than the boys to read the topic as much as possible to understand the relevant information and ideas.In addition,girls are more targeted than boys.Third,in the process of solving the specific problem of geometric proof,junior middle school students' goal orientation ability is insufficient.Fourth,geometry proof object selective joint ability of junior middle school students in geometry has a significant effect in the test scores of junior middle school students,especially for the more difficult geometric proof,coupling selectivity of target ability of junior middle school students is higher,the test of the performance is better in geometry proof.Finally,in order to strengthen the ability of target selective connection in geometric proof of junior middle school students,the paper puts forward the relevant training strategies from the perspective of the constituent elements of the target selectivity.In the aspect of knowledge connection,the knowledge network is constructed,and the basic knowledge is consolidated.In the aspect of target transformation,we should cultivate the awareness of goal orientation and promote the ability of reverse analysis.In the aspect of problem solving,we should strengthen the consciousness of reflection and form the habit of "reasoning according to",strengthen the monitoring and training of problem solving,and improve the level of problem solving.
