| With the rapid development of society and science and technology,information technology has a positive impact on various fields of society,among which,it has a revolutionary impact on the field of education and is of great significance to the education informatization.The use of information technology can enrich the content of learning and presentation,make it intuitive,convenient and fast presentation,thereby improving classroom efficiency and training students' abilities."Compulsory Education Mathematics New Curriculum Standards(2011 Edition)" points out that modern information technology should be reasonably applied in teaching,and the course objective points out that students should be trained in geometric intuitive ability.Geometry content is one of the key contents of junior high school mathematics.It is widely used in real life and it is very helpful to the cultivation of students' geometric intuitive ability.In the eighth grade geometry teaching,it is a critical period to cultivate the students' geometry intuition ability.However,the survey found that the actual teaching status of the eighth grade geometry is not ideal.Most teachers still use the traditional teaching method.The current geometry teaching is boring and students do not feel geometry Interest;blackboard hand movements are slow,classroom efficiency is reduced;teaching abstraction is not conducive to the training of geometric intuitive ability.China's mathematics education software "Super Sketchpad" provides strong support and help for geometry teaching.The super sketchpad is quick and intelligent in drawing,and can also make the geometry teaching dynamic,making it more intuitive,and solves the key and difficult problems in geometry teaching.Applying the super sketchpad to geometry teaching is one of the important methods to solve the above problems.The author has carried out related research on the application of super sketchpad in the eighth grade geometry teaching.The author chooses the task-driven teaching mode through the analysis of the eighth grade geometric knowledge points and the analysis of the learners,and proposes the application strategy of the super sketchpad.Use super sketchpad to create situations,mobilize students 'interest in learning,stimulate students' curiosity,use super sketchpad to quickly and intelligently draw,improve drawing speed and drawing accuracy,and give students more time to think and explore,thereby improving classroom efficiency;use super sketchpad Dynamic and intuitive teaching,through intuitive image presentation and let students operate hands-on experience,cultivate and improve students' geometric intuitive ability.Teaching experiments are conducted by designing and applying teaching cases of super sketchpads.The pre-experiment test was conducted through the questionnaire survey method,and the post-experiment test was conducted through the questionnaire survey method,interview method and periodic test.From the analysis of experimental data,the application effect of the super sketchpad was obtained.The purpose of this study is to provide a reference for firstline mathematics teachers to reasonably use the super sketchpad in the eighth grade geometry teaching.Through research,it is found that the proper use of "super sketchpad " in the eighth grade geometry teaching can be of great help to students' learning interest,classroom efficiency,and the cultivation and improvement of geometry intuition.Research also has certain deficiencies and limitations.Such as the sample is not large enough,the research period is short,etc.But I believe this research can still provide some help for the first-line math teachers to use the super sketchpad and the subsequent research of the super sketchpad. |
