Research On The Cultivation Of The Core Literacy Of High School Students' Mathematical Intuitive Imagination Based On Mixed Teaching

With the reform of high school mathematics teaching,the concept of core literacy has been repeatedly mentioned and discussed.Frontline teachers have made many efforts to cultivate students' core literacy abilities in teaching.Intuitive imagination,one of the six core literacy,has always been the focus of teaching.However,due to its abstraction and complexity,intuitive imagination has also become a difficult point in teaching.To meet the high requirements for talents' ability and thinking in the new era,it is imperative to systematically and effectively cultivate students' intuitive imagination ability.The author in poring over the ordinary high school mathematics curriculum standards(2017 edition),after considering intuitive imagination core literacy abstract complex characteristics,based on the intuitive imagination literacy status quo of high school students and cultivate situation,with the aid of information technology teaching means,scientific and effective training strategies for the hybrid teaching is put forward,and the applicability of the checked through three rounds of action research in teaching.Research in conic curve and equation of curriculum content,for example,online teachers to self-study through the Course Maker software to make teaching video is given priority to,offline with group cooperation study,mainly on problem solving,choose high grade a class three rounds of action research,summed up the teaching model based on hybrid effective strategies of cultivating high school students intuitive imagination core literacy,reach an intuitive imagination for math teachers in the teaching practice reference for the fall to the ground.This paper consists of the following four parts:The first part is theoretical research,including the first two or three chapter elaborated the selected topic background,research purpose and meaning of the content and method,define the core concept of this study Illustrates the eph lyden tal the teaching theory of constructivism learning theory,humanism learning theory,cognitive learning theory and the research of this learning community Through the literature research at home and abroad are summarized in the composite core literacy training,teaching and intuitive imagination and cultivate high school students based on hybrid teaching intuitive imagination research present situation.The second part is the fourth chapter,which is the investigation of the current situation.This study adopts the questionnaire survey method to investigate the current situation of students' intuitive imagination,and tests the students' ability of combining geometric intuitive numbers and shapes with spatial imagination through the pre-test questions.The third part includes the fifth chapter six and seven,about hybrid teaching high school students intuitive imagination design implementation and effect analysis of action research First preliminary build intuitive imagination literacy training strategy,and accord ing to the strategy to carry out the action research teaching in the first round,after the first round of action research,to improve the initial build strategy,and to carry out the second and third rounds of action research,summed up the hybrid teaching mode to develop effective strategies for high school students intuitive imagination The testing of students test after interview way to culture the students' intuitive imagination accomplishment effect is analyzed.The fourth part is the eighth chapter,conclusions and prospects of the research and reflection on the deficiencies and problems to be solved in the research,for the future in-depth research.The conclusions of this study include :First,high school students' visual imagination literacy needs to be improved.At present,more than half of high school students' visual imagination core literacy is in the level one,that is,the requirement of high school graduation,which is also the proposition basis of the mathematics academic proficiency test for high school graduation.Only one fifth of the students can reach Level 3,which is based on the required optional compulsory and elective courses of geometric intuition and spatial imagination related content on the achievement of visual imagination core literacy requirements,students' visual imagination literacy level needs to be improved.Second,the implementation of the cultivation strategy of intuitive imagination literacy in the course of conic curve and equation can effectively improve the level of students' intuitive imagination ability,which is embodied in the ability of intuitive feeling and expression and the ability to construct intuitive models by combining the ideas of numbers and shapes.Thirdly,effective strategies for cultivating high school students' intuitive imagination ability based on mixed teaching include seven core links: micro-video explanation,blackboard writing,comment,assignment,display,sharing,problem solving,expansion,summary and exchange of experience.
