Teaching Experiment Research On Cultivating High School Students’ Intuitive Imagination Based On Network Sketchpad

Education informatization has become an inevitable trend in the digital information age,and the integration of information technology and curriculum has become an important means of teaching reform.In the teaching suggestions of "ordinary high school mathematics curriculum standard(2017 edition,2020Revision)",it is proposed to "pay attention to the application of information technology,realize the deep integration of information technology and mathematics curriculum","use computer to show the process of function image and geometric figure movement and change",etc.The effective integration of mathematics and information technology has become a necessary means of mathematics development and teaching reform.Intuitive imagination refers to the ability to perceive the shape and change of things with the help of geometric intuition and spatial imagination,and to understand and solve mathematical problems with the help of spatial form,especially graphics."Mathematics curriculum standard for senior high school(2017 version,2020Revision)" puts forward: "the core quality of subject is the concentrated embodiment of educational value,and is the correct values,necessary character and key ability gradually formed by students through subject learning".Intuitive imagination is one of the six core qualities of senior high school mathematics,and the cultivation of intuitive imagination quality of senior high school students is of great significance.China Academy of Sciences Academician Zhang Jingzhong and his team developed a "Internet plus dynamic mathematics" teaching aid software "web Sketchpad" based on the Super Sketchpad.The deep integration of network Sketchpad and mathematics curriculum content can cultivate students’ intuitive imagination literacy by using the intuitive display of knowledge.The author intends to investigate the use of multimedia in the teaching and learning of high school students about the cultivation of intuitive imagination literacy,and explore the teaching strategy of cultivating high school students’ intuitive imagination based on the network Sketchpad,so as to promote students’ knowledge understanding and enhance their intuitive imagination literacy,and provide reference for front-line teachers.This research is mainly divided into the following aspects1.Through the methods of literature research,student questionnaire survey and teacher interview,combined with the students’ five week weekly test results,we understand the use and attitude of multimedia in the teaching and learning of high school students’ intuitive imagination cultivation.We find that students’ intuitive imagination ability is weak,teachers seldom use drawing software such as Geometer’s Sketchpad to assist teaching,and students and teachers’ understanding of multimedia in teaching the use of is supportive and appropriate.2.Based on the current situation of high school students’ imagination training,the paper puts forward some strategies.And from the intuitive imagination in the situation and problems,knowledge and skills,thinking and expression and communication and reflection of the four aspects of the performance of the strategy analysis,put forward the following strategies:(1)situation and problem strategy:create intuitive life situation,cultivate the consciousness of using pictures to understand pictures;create operational problem situation,cultivate the ability of drawing;create exploratory situation,cultivate the thought of combining number with shape.(2)Knowledge and skill strategy: the combination of concrete and image to understand the essence of knowledge;the combination of dynamic and static to cultivate imagination;the combination of number and shape to form transformational thinking.(3)Thinking and expression strategies: strengthen the representation of graphics and charts to form image thinking;transform the number and form of knowledge to develop diversified expression.(4)Communication and reflection strategies: combined with the multi representation of knowledge,optimize the graphic language communication;create classroom practice inquiry,enhance classroom reflective learning.3.Choose the knowledge that supports intuitive imagination in the content of mathematics course to carry out micro experiment teaching and test paper examination.According to the test results,the effectiveness of the teaching strategy of cultivating students’ intuitive imagination based on the network Sketchpad is analyzed.This experimental study shows that: the teaching strategy of cultivating high school students’ intuitive imagination based on the network Sketchpad can effectively promote the learning of high school students’ knowledge and skills,promote the cultivation of the ability of learning to draw,recognize and analyze problems with pictures to form problem-solving ideas,improve the ability of high school students’ intuitive expression and combination of number and shape,and cultivate high school students’ number intuitive imagination literacy.
