The Cultivation Research Of High School Students' Mathematics Visual Imagination Accomplishment Based On TI Graphic Calculator

Mathematic intuitive imagination literacy is one of the high school mathematics subject core literacy,improve students' intuitive imagination literacy is important significance to improve the quality of teaching.This study attempts to explore the use of TI graphing calculator to cultivate the students' mathematical literacy intuitive imagination.Using literature analysis,with reference to "the ordinary high school mathematics curriculum standard" intuitive imagination of mathematics accomplishment evaluation level classification,designed the questionnaire,the present development of high school mathematics intuitive imagination through sampling test,reliability according to 0.811,validity of 0.744,The questionnaire has good reliability and moderate validity.Through the questionnaire survey of 105 students in two classes of grade two of xx middle school in xx city,the status quo of high school students' intuitive imagination quality in mathematics is as follows:72.2% of the students in grade two have reached the level of intuitive imagination in mathematics.30.9% of the students reached level 2.High school students have a general grasp of building geometric figures through imagination,raising mathematical problems with the help of graphics,and exploring ideas for solving problems.While only 5.2% of those who reach level 3 standard,comprehensive utilization of high school students for graphics and graphics relationship and understand the relations between the branch of mathematics,by imagining intuitive expression to complex problems such as insufficient mastery.According to the high school mathematics intuitive imagination literacy development present situation and analysis,put forward based on the TI graphing calculator ways for the cultivation of the high school mathematics intuition thought quality is: use opportunely "graphics" operation,strengthen the geometric understanding;Tracing graph dynamics and exploring mathematical laws;Use image analysis to understand mathematical relations;Improved edit operation,reflecting the mathematics essence.Select the two classes of senior grade two,respectively,as that in comparative classes and experimental classes and control experiment,the experimental classes and intuitive imagination that in comparative classes students mathematics literacy a pretest scores for independent samples T test,shows that there was no significant difference between two class.On the way of teaching in experimental class practice,in that in comparative classes by routine teaching,through experimental classes and intuitive imagination that in comparative classes students mathematics accomplishment after the results of independent sample t-test,get the experimental class students intuitive imagination literacy is significantly higher than that in comparative classes,students practice shows:TI graphic calculator based on high school students mathematics visual imagination literacy training way is effective.
