| In recent years,the term “core competency” has become the key word for the new round of education reform,thus,education should foster the essential characters and key abilities that are required for students to be able to adapt to lifelong development and social development.Only the students' mathematics key competencies are truly implemented and fostered,it could enable students to actually master the knowledge & skills,method of thinking and application consciousness of functions,and facilitate students' lifelong development.Senior grade one function is the core content of high school mathematics,during teaching,we discover that students use geometry intuition frequently to help them understand features of functions,reduce the level of abstraction of functions,.Accurate functional image will help students better solve functional problems,therefore,it is crucial to improve students' intuitive imagination literacy.In this paper,by taking intuitive imagination literacy as the research object and the functional knowledge in compulsory I textbook under PEP A edition as the knowledge carries,and with adoption of literature review method,questionnaire method and other research methods,the measuring and testing system towards the mathematics intuitive imagination literacy of senior one students in function learning was built,to prepare measuring and testing tools,determine measuring and testing object,and process and analyze data etc.from the perspective of teachers and students as well as qualitative and quantitative,the intuitive imagination literacy level of senior one students was analyzed,and the problems and deficiencies between students and teachers in function teaching was determined.In the end,the teaching suggestion of fostering students' intuitive imagination literacy in function teaching was put forward,to facilitate fostering of intuitive imagination literacy for senior one students,and provide a reference for function teaching of first-line teachers.According to the survey,it showed that:(1)the senior one students in our school and branch were under low overall level for intuitive imagination literacy;(2)students' level in function mapping and image analysis was closely linked to intuitive imagination level,and the level of intuitive imagination level affected the academic performance of function;(3)Students' intuitive imagination literacy was related to student level,in the campus with favorable entrance test score for middle school,the students there had higher level in intuitive imagination literacy;(4)There was no relation between students' intuitive imagination literacy and gender,the level of boys and girly was basically the same.In the end,the teaching suggestions offered by the author:(1)Enhance students' training for their function image drawing ability to ensure they can draw accurately.Pay attention to the basic drawing training of basic function image and image transformation.Strengthen the training of combining numbers with shapes,let students master the method of intuitive imagination.Make function teaching a topic,and make function problems more intuitive;(2)Enrich the teaching methods and strengthen the application of information technology.Use tutorials and multiple evaluations.Give students feedback timely in class and consolidate their intuitive imagination;(3)Standardize the classroom teaching,ensure the intuitive imagination,and understand the academic situation.Put the students first,improve our teaching methods and change our outmoded conventions.Lay emphasis on the training of the important skill of intuitive imagination,change our outdated teaching concepts and teaching methods. |
