Research On The Current Situation And Training Strategy Of Intuitive Imagination Literacy Of Senior Two Students In K City ——Take Conic As An Example

Visual imagination quality is one of the six core qualities proposed by the high school mathematics curriculum standard.Establishing a reasonable and effective training strategy of visual imagination quality is one of the hot issues discussed by high school mathematics teachers.Senior two is a key period for the development of senior high school students' mathematical literacy.Mastering the current situation of students' intuitive imagination literacy at this stage can help teachers better formulate teaching plans,clarify educational objectives,and then carry out more targeted training to improve students' intuitive imagination.This study combines the methods of literature,test,questionnaire and interview to investigate the current situation of visual imagination literacy of senior two students in K City,and studies the factors affecting the development of visual imagination literacy.Firstly,238 senior two students in a senior high school in K city were investigated by issuing the adapted learning motivation scale.At the same time,the test paper formulated according to the evaluation framework extracted from this study was issued,and a total of 240 students in this middle school accepted this test.Then,four mathematics teachers and twelve students were interviewed,and the interview results were summarized and analyzed.From the analysis of the test paper,questionnaire and interview results,the development status and influencing factors of students' intuitive imagination literacy in grade two of senior high school are obtained;Finally,according to the results,the strategies of cultivating and improving students' intuitive imagination literacy in conic are given.These strategies are used to carry out teaching activities and record the teaching process,and two teaching cases are obtained.These two cases are the teaching cases of ellipse and its standard equation and hyperbola and its standard equation.The main conclusions of the study are as follows:(1)at present,the overall level of visual imagination literacy of senior two students in K city is at the upper middle level,and most students have reached the level 2 required by the curriculum standard.? in the four manifestations of intuitive imagination literacy: establishing the relationship between number and shape,describing problems with geometric graphics,understanding problems with geometric intuition,and using spatial imagination to understand things,the test scores of students are getting lower and lower,which reflects the higher and higher requirements of the four manifestations for the cultivation of students' intuitive imagination.(3)at the gender level,the level of intuitive imagination literacy of boys is significantly higher than that of girls.At the level of Arts and Sciences,the intuitive imagination literacy of science students is significantly higher than that of liberal arts students.At the class level,the intuitive imagination quality of science class is significantly higher than that of liberal arts class.(4)self efficacy,achievement motivation and communication motivation can significantly affect students' intuitive imagination literacy.(5)students' learning methods and teachers' teaching methods play an important role in the development of students' intuitive imagination literacy.They jointly promote the development of students' intuitive imagination literacy.Based on the above research results,the following five training strategies are proposed: ? skillfully use variants to improve self-efficacy;(2)jointly explore the property theorem and develop communication motivation;(3)do mathematical experiments and tell mathematical stories to promote achievement motivation;(4)standardize drawing and form good habits;(5)use Sketchpad tools to perceive the formation of concepts.
