Research On The Methods Of Cultivating The Intuitive Imagination Ability Of High School Students

With the continuous deepening of curriculum reform,cultivating and improving the core literacy of students in mathematics has become the main curriculum goal.Taking teaching material as the main line and cultivating students 'comprehensive ability is the key to improving and developing students' core literacy.Intuitive imagination,as one of the six core literacy,permeates the visual imagination of high school mathematics curriculum.It is an important means of discovering,analyzing,and solving mathematical problems.It is also the thinking basis for exploring problem ideas and mathematical reasoning.Improving students 'core literacy by cultivating students' intuitive imagination is a hot issue in the current curriculum reform.Through the methods of literature analysis,questionnaire and case analysis,the content of the conical curve chapter is used as the teaching carrier,and the methods of cultivating the visual imagination ability of high school students are explored from the theoretical and practical aspects.Based on the literature research,the core concepts such as "intuitive imagination ability" were defined,and relevant training methods at home and abroad were summarized.The test papers that complied with Tianjin RJ Middle School students' ability level were compiled.Based on the test results,the classes with the same level of intuitive imagination ability were selected,two as experimental classes and two as control classes.Based on the theoretical foundations such as constructivist teaching concept and image thinking,and combined with the problems of students' intuitive imagination,they were formulated to train students Instructional design of intuitive imagination ability,teaching students in the experimental class.Studying the effectiveness of teaching methods and testing the effectiveness of teaching.According to the comparative analysis of practical effects,it is found that the students in the experimental class have a higher level of visual imagination than the control class,that is,(1)the introduction of background knowledge inquiry to stimulate students 'interest in learning;(2)carefully asked questions to cultivate students' inquiry ability;(3)Infiltrate the thought of combining numbers and shapes to cultivate students 'drawing ability;(4)use multimedia to display the movement process of graphic changes to cultivate students' dynamic thinking;(5)multiple angles training of students 'intuitive thinking ability and other methods have a certain degree of training students' intuitive imagination ability effect.
