| The new curriculum reform,presided over by Wang Shangzhi of Beijing Normal University and Shi Ningzhong of Northeast Normal University,has formulated the mathematics curriculum standard of general high school(hereinafter referred to as the "new curriculum standard").The goal of the new curriculum standard is not only to continue to pay attention to the development of "four bases" and "four abilities",but also to require students to develop the core quality of mathematics subject in mathematics learning.Intuitive imagination literacy is a very important core literacy of mathematics,which has a great impact on the development of high school students' lifelong literacy.In the past two years,a lot of research has been involved in the cultivation of high school students' intuitive imagination literacy,but the reality is that the development of high school students' intuitive imagination literacy in China is still not optimistic.One important reason for this contradiction is that the relevant research has not been organically combined with the actual teaching content,so the theoretical results of these studies have not yet been fully promoted to the actual teaching.Therefore,the author tries to study the high school function teaching under the guidance of intuitive imagination,and strives to cultivate students' intuitive imagination literacy through further refining the function teaching strategy.Function is one of the five subjects in senior high school mathematics compulsory course,and it is also the main line running through senior high school mathematics course.Because of its dual characteristics of "number" and "shape",function is an important carrier to cultivate students' intuitive imagination.However,through the investigation,it is found that the function is still the knowledge module of high school students with big problems in mathematics learning."Abstract is difficult to understand","it is difficult to raise interest" and "calculation is complex" have become the common feelings of students for the function.This paper aims to study the students' and teachers' understanding of the function and their learning status,and to simplify the development of students' mathematical ability in the process of learning the function It is necessary to analyze and put forward teaching strategies to improve the cultivation of students' intuitive imagination core literacy in function teaching.This study is divided into three parts.The first part is based on the understanding of the high school students' attitude towards function knowledge,learning status and the influence of function on the development of high school students' mathematical ability.It makes interviews,questionnaires and questionnaire analysis on the current situation of function knowledge learningand the development of intuitive imagination literacy of high school students.The second part is based on the survey results and related theories,as well as the requirements of the new curriculum standard for function teaching,to provide a function teaching strategy under the guidance of intuitive imagination.The third part is based on the function teaching strategy design case under the guidance of intuitive imagination,and provides the teaching design of two topics:the monotony of function and the image and nature of exponential function.The research is devoted to improving the effect of function teaching and the quality of visual imagination in the practice of function teaching.According to the requirements and research results of the new curriculum standard for the quality of linear imagination,the author believes that the teachers of the first function teaching under the guidance of intuitive imagination can carry out teaching from the following points.First,teachers should pay attention to the cultivation of students' interest in function learning and promote the change from passive acceptance to active learning;second,put function graphics in the "primary position" of students' function learning process,pay attention to the inspiration and guidance of intuitive graphics to students,and spare no effort to improve students' drawing ability and train students' consciousness of using graphics;third,teachers should combine the intuitive imagination with the teaching objectives,teaching methods and function knowledge points to ensure the improvement of students' intuitive imagination while improving the function teaching effect;fourth,follow the principle of gradualness,the improvement of students' intuitive imagination needs a process,teachers should consider the actual level of senior one students,and leave enough time and space for students to explore independently.To make students form ability in the accumulation of experience. |
