A Study On Cultivating Students Mathematics Abstract Literacy In Function Teaching

A new curriculum reform centered on core literacy has begun,and it is the responsibility of mathematics educators to cultivate students' core literacy in mathematics.Mathematics abstract literacy as the primary mathematics core literacy,based on classroom teaching to cultivate students' mathematical abstract literacy has great significance.Through the test survey method,using SPSS 25.0 and Excel to analyze the test paper,the present situation of mathematics abstract literacy of senior 1 students was obtained.In the corresponding level of mathematics abstract literacy,73%,62%and 29% of the students reached level one,level two and level three,respectively,and the proportion of the students who reached the corresponding level of abstract literacy decreased continuously with the increase of the level of mathematics abstract literacy.On the level of mathematical abstract literacy in the four mathematical activities,the present situation of students' mathematical abstract literacy is manifested in the situation and problems>thinking and expression> knowledge and skills>communication and reflection.According to the present situation of students' mathematics abstract literacy,the teaching strategy of cultivating students' mathematics abstract literacy in four mathematics activities is obtained.In the dimension of situation and problem :(1)creating effective teaching situations so that students can fully experience the process of mathematical abstraction;(2)guiding students to generalize conclusions and paying attention to the problems existing in the process of generalization.In the dimension of knowledge and skills:(1)setting reasonable teaching objectives and clarifying students' cognitive needs for basicknowledge of mathematics;(2)constructing syste matic knowledge system to promote students' understanding and penetrating of mathematics knowledge;(3)using reasonable information technology to promote students' understanding of corresponding mathematics contents.In the dimension of think ing and expression :(1)mastering the use of mathematical language,which promoting students to express relevant mathematical problems skillfully;(2)paying attention to the infiltration of mathematical ideas and guiding students to understand the general and general methods of mathematics.In the dimension of communication and reflection:(1)Paying attention to the practical application of knowledge,which closing the distance between mathematical knowledge and real life;(2)carrying out mathematical communication and reflection,which promoteing students to exchange and accumulate corresponding experience.Taking the three teaching classes of basic elementary function(I)as an example,Firstly,the corresponding teaching contents are analyzed by using the theory of mathematics abstractness analysis,then the course objectives of the corresponding teaching contents are analyzed,and then the corresponding teaching strategies are integrated into the four stages of APOS teaching.The results of teaching experiment show that the teaching design and teaching strategy of cultivating students' abstract literacy in mathematics are effective.
