Research On Teaching Strategy Of Promoting The Mathematical Knowledge Construction Of Senior High School Students

With the rapid development of modern society,the mode of talent training has changed.In the reform of mathematics education,more and more attention has been paid to the cultivation of mathematical core literacy,in order to better adapt to the development of the future society.Therefore,in mathematics teaching,more emphasis is put on the process of students’ active construction of mathematical knowledge on the basis of existing experience and more attention is paid to the active generation and application of mathematical knowledge.However,there are still many problems in the reform of senior high school mathematics teaching.Students’ autonomy and criticality in the process of mathematics learning still need to be improved.Therefore,it is necessary to investigate the situation of high school mathematics knowledge construction and put forward corresponding teaching strategies to promote the improvement of high school students’ mathematics core literacy.This research method mainly includes literature research method,investigation research method,expert consultation method and case analysis method.First of all,on the basis of consulting and analyzing the literature on the construction of mathematical knowledge,combined with expert consultation,the concept of high school mathematical knowledge construction is defined and the theoretical framework of high school mathematical knowledge construction is constructed.Secondly,the questionnaire is used to investigate the actual situation of high school students’ mathematics knowledge construction and the reasons for the problems are analyzed;Using the method of interview,the teaching methods adopted by high school teachers in the process of promoting students’ knowledge construction is investigated and the existing problems are identified.Finally,the corresponding teaching strategies are put forward and a typical case of high school mathematics is used to analyze its specific implementation steps and precautions.Through this research,the concept of high school mathematics knowledge construction is clarified and its characteristics,approaches,mechanisms and influencing factors are analyzed.By using the questionnaire,it is concluded that high school students’ autonomy of mathematics knowledge construction is not high and the effect is not good;Through interviews with front-line teachers,we know that high school mathematics teachers’ teaching methods still put too much emphasis on teachers’ control of the classroom and lack of teaching methods to guide students to explore independently and cooperate with each other.Finally,the teaching strategies to promote the construction of high school students’ mathematical knowledge are studied and the strategy system is divided into five parts according to the logical order of high school mathematics teaching.First,the foundation of high school students’ mathematical knowledge construction should be made clear,which can be divided into two aspects: the study of students’ thinking characteristics and students’ mathematical knowledge experience.Second,mathematical problem situations to stimulate students’ construction motivation,including the creation of problem situations from life and other disciplines,the problem situations in mathematical stories and intuitive demonstration situations should be created.Third,students should be guided to explore actively and construct high school mathematics knowledge system.The strategies include leaving space for students to explore,establishing a learning community,encouraging students to put forward ideas,expanding new knowledge,guiding students to use mind map and using unit teaching method.Fourth,mathematical problem solving,divided into two kinds of classroom internal and external strategies should be valued.Fifth,the way of mathematics evaluation should be changed.Students should be guided to evaluate the way of mathematics knowledge construction independently and cultivate their ability of reflection on construction.
