Research On The Strategy Of High School Mathematics Example Teaching Based On The Cultivation Of Core Literacy

Core literacy is the concentrated expression of quality,ability and values,and it is the basic requirement for students under the background of the new era.Taking core literacy as the keynote is the inevitable trend of the new curriculum reform.Example teaching is the main form of classroom teaching,and it is also an important carrier to implement students’ core literacy.Therefore,how to use example teaching to cultivate students’ core literacy has become the main research direction of mathematics educators.This study summarizes the relevant theories of core literacy and example teaching through the literature research method,using the method of questionnaire survey and statistical analysis to reveal the current situation of high school mathematics example teaching and the cultivation of students’ core literacy,proposes example teaching strategies based on core literacy training,and the applicability of teaching strategies is expounded by using case analysis method.The main contents are as follows:（1）Through a sample survey of high school mathematics teachers in H city,analyze the problems existing in the process of cultivating students’ core literacy:some teachers do not pay much attention to standardizing students’ problem-solving process and the penetration of mathematical thinking methods;some teachers’ teaching methods are backward,and the relevant teaching and statistical software are used less frequently;some teachers rarely carry out mathematical modeling activities and lead students to experience the whole process of data analysis in the teaching of examples,etc.（2）In response to the above problems,proposes example teaching strategies to promote the development of students’ core literacy:Cultivate students’ mathematical abstraction literacy by establishing symbolic awareness,proposing mathematical models,and abstracting general methods of problems;Cultivate students’ logical reasoning literacy by means of multi-directional discussion of proof ideas and focusing on standardizing the process of argumentation;Use the measures of cultivating problem awareness and carrying out modeling activities to cultivate students’ mathematical modeling literacy;Use teaching software to help students establish number-form connections,so as to cultivate their intuitive imagination literacy;Develop students’ mathematical operation literacy by adopting strategies that focus on the explanation of operation rules and show a variety of operation ideas;Relying on the explanation method of rich probability and statistics knowledge,guide students to experience the whole process of data analysis,and integrate statistical software to cultivate their data analysis literacy.（3）Combining both problem-solving and problem-resolving examples,apply the example teaching strategies under the cultivation of core literacy to specific case teaching,to promote the formation of core literacy and example teaching community,really make the training of core literacy implemented in the example teaching.
