Research On Function Teaching Strategy In Senior High School From The Perspective Of Intuitive Imagination Core Literacy

The core accomplishment of intuitive imagination is one of the six core accomplishment of mathematics that high school students should have,and it is the premise and foundation to promote the continuous improvement of students’ thinking ability and problem analysis and solution ability.Function is not only the key content of high school mathematics curriculum system,but also a knowledge module with strong abstractedness.In addition,because function has dual characteristics of both number and shape,function module is also an important content carrier and support for cultivating and improving students’ core literacy of intuitive imagination.In this study,on the basis of existing research results at home and abroad,in theory,theory of multiple representation and the zone of proximal development in the new curriculum standard as the theoretical basis,put forward the relevant contents of the integrated use of questionnaire investigation,interview method and test method,according to the understanding of the status quo,found the problem,puts forward the train of thought of research,from the students’ learning and teachers’ function teaching two angles,the analysis of current status of teaching high school function,at the same time,combining with the research results,respectively from the perspective of students and the teacher pointed out that the high school function to the reality of the problems existing in the teaching process,such as students lack of interest in function learning,learning motivation is insufficient;The students’ function learning is superficial and their application ability is insufficient.The students’ ability of combining numbers and shapes is insufficient,and the accomplishment of visual imagination needs to be strengthened.Teachers do not have a good understanding of the literacy of intuitive imagination,and the functional teaching design lacks the guidance of intuitive imagination.Function classroom teaching method is more traditional,the classroom teaching reform is insufficient;Intuitive imagination accomplishment in function teaching is not in place,lack of effective measures.In view of the existing problems found in the survey,based on the perspective of core literacy of intuitive imagination,the corresponding improvement strategies of function teaching are proposed,such as digging into the background and creating situations to stimulate students’ interest and motivation in function learning.Reform the way,optimize the means,deepen the students’ function knowledge grasp and understanding;Independent practice,strengthen the application,improve the function content teaching effect and effectiveness;Strengthen training,permeate thought,realize the cultivation and promotion of intuitive imagination accomplishment.Finally,taking the content of "functional monotony" as an example,the corresponding teaching design is given based on the core literacy of intuitive imagination,in the hope of providing reference for front-line teachers.
