A Practical Study On Mathematics Key Ability Training Of Multi Solution In High Schools

The rapid development of science and technology has promoted the change of social progress.Mathematics,as a basic subject,plays an irreplaceable role in the formation of rational thinking and the promotion of individual intelligence development.In recent years,the problem of cultivating students’ key ability in mathematics has been paid close attention by the educational circles,and a multi problem as the most commonly used teaching method in variant teaching has been widely used by first-line teachers.The purpose of this paper is to investigate the actual situation of multi solution teaching in high school classroom.Based on the development of students’ key ability in mathematics,this paper analyzes the existing problems in multi solution teaching in high school mathematics,optimizes the teaching according to the problems,designs the teaching activities and practices in teaching to gradually develop students’ mathematics key ability.Combined with the theoretical research of the key ability of mathematics by experts,this paper adopts the methods of questionnaire,test paper survey and experimental research to carry out practical research on the cultivation of the key ability of mathematics in high school students.First of all,the core concept is defined and interpreted,this paper mainly defines and interprets a problem and multiple solutions,mathematical key ability,and the evaluation of mathematical key ability is modeled.Secondly,selected a certain number of high school students and first-line teachers,through the questionnaire survey found that,(1)The main problems of students in a multi-question solution are unclear examination questions,unclear thinking,etc.(2)students’ ability of mathematical abstraction,logical reasoning and mathematical modeling is relatively weak;(3)teachers’ evaluation of multi solution teaching is very high,but limited by teaching time and personal energy,the quality of multi solution teaching is not high;(4)some teachers think that a multi solution teaching is mainly helpful to the top students,but not to the middle students and the students with learning difficulties.Based on the above conclusions,combined with the cultivation of six aspects of the key ability of mathematics,this paper gives a teaching countermeasure of multiple solutions :(1)Preparation before class,extraction of key teaching events;(2)Reading examination questions to cultivate students’ ability to understand;(3)independent thinking,develop mathematical thinking ability;(4)expression display,cultivate mathematical representation ability.Finally,the concrete practice operation is carried out,the proposed multi solution teaching strategy is analyzed,the experimental class and the control class are set up,and the key ability of mathematics is double examined by the way of test questions examination and final examination.The experimental results show that the teaching of multiple solutions to one problem improves the students’ mathematics key ability and problem solving ability,especially the abstract ability of mathematics and the ability of logical reasoning.
