Research On The Teaching Strategy Of "Figure And Geometry" In Junior Middle School To Promote The Development Of Intuitive Imagination Literacy

Disciplinary core literacy has become an important topic of research by educational researchers."General High School Mathematics Curriculum Standards(2017 Edition)" takes intuitive imagination as one of the six core mathematics qualities." General High School Mathematics Curriculum Standards(2017 Edition)" takes intuitive imagination as one of the six core mathematics qualities,Put forward clear requirements for its cultivation,Junior and high school mathematics are coherent.The cultivation of intuitive imagination literacy does not happen overnight.Consistently value from junior high school,Plays an important role in the development of students' mathematical thinking." Graphics and Geometry" carry the important task of developing intuitive imagination at the junior high school stage,Focusing on spatial imagination ability in past teaching,leading to the lack of development of intuitive imagination literacy,This study explores the teaching of "graphics and geometry" in junior high school from the perspective of intuitive imagination literacy development,in order to fully tap and play the role of this section in the development of students' mathematical literacy.This research is based on literature analysis,and try to explore the connotation and manifestation of intuitive imagination literacy in junior high school through interviews,classroom observations,etc.Understanding the junior middle school mathematics teacher's understanding of intuitive imagination and the status quo of teaching,through the preparation of intuitive imagination test questions,students are tested to understand the specific situation of the intuitive imagination ability of junior high school students,Found the problem.Finally,in view of the existing problems,a teaching strategy is proposed and a case design is carried out.Through researching,it is obtained: Junior high school intuitive imagination literacy refers to a kind of thinking ability that uses basic graphics to expand imagination,which is manifested in four aspects: use spatial imagination to recognize things;describe the movement and changes of graphics;use geometric intuition to understand problems;establish numbers and Shaped relationship.In actual teaching,teachers have a correct but incomplete understanding of the connotation of intuitive imagination,and are not clear about the specific form of expression.Although they consciously cultivate students' intuitive imagination,they have no clear direction and lack of actual teaching cases.Junior high school students have basic geometric intuition ability,but there are still some difficulties in using geometric intuition to understand the problem and establish the connection between number and shape.In view of the existing problems,the teaching strategy of "graphics and geometry" in junior high school from the visual angle of imagination is proposed,Attach importance to drawing ability and burst out geometric intuition;based on geometric models,develop spatial imagination;develop intuitive imagination literacy through combination analysis of number and shape.
