Research On High School Mathematics Teaching Based On Geometry Sketchpad

The 21 st century is an information age.With the rapid development of society,education informationize attracts more and more attention in the world.From the perspectives of mathematics subject,traditional teaching has been unable to satisfy the requirements to promote comprehensive development of students.Therefore,modern information technology must be applied for teaching as an auxiliary means,so as to optimize classroom efficiently.Firstly,under the demand for the integration of information technology and subject teaching,the current thesis presents the research background,purpose and significance,and related theoretical basis in accordance with the requirements of the new curriculum standard.Through the analysis of the research status of domestic geometry sketchpad,it is found that most of the existing literatures focus on the function and teaching strategies of the geometrical sketchpad in the process of teaching,as well as its benefits and drawbacks.Secondly,based on the functions,characteristics,effects and application scope of the Geometry Sketchpad,the parts extracted from high school mathematics textbooks PEP edition(A)are selected to design lessons which can apply the Geometry Sketchpad widely under the guide of the principles and strategies that should be followed in the process of teaching design which are summarized through concluding literatures.After practice,attitude of students towards application of geometric sketchpad to mathematics teaching and its influence on mathematics teaching are analyzed through questionnaire.Finally,the merits of applying Geometry Sketchpad in classroom teaching are concluded.In addition,the suggestions are put forward for teachers to use geometry sketchpad,so as to provide a reference for teachers to apply geometry sketchpad in teaching afterward and promote geometry sketchpad to play a more important role in high school mathematics teaching.
