Research On The Integration Of "Geometric Sketchpad" And Mathematics Teaching In Junior Middle School

With the progress of society,the development of science and technology,and the change of educational concept,Shanxi province implemented curriculum reform in 2011,advocating the integration of information technology into teaching,letting students be the main part of the classroom,with students as the center.In the current information age,how to integrate information technology and mathematics teaching and how to use information teaching tools reasonably in mathematics teaching is a problem that mathematics teachers pay special attention to.Because these tools can help mathematics classroom improve the teaching effect,but also let teachers and students understand the changes brought by information technology to the classroom.Geometric Sketchpad is an information teaching tool with simple operation and rich drawing function,so it is often used in mathematics teaching.Under the combination of the relevant literature on the integration of Geometric Sketchpad and junior high school mathematics and the requirements of curriculum reform in Shanxi Province,the main research contents of this paper are as follows:First,the progress of science and technology,the reform of education,constructivism,humanism,mathematics "re-creation" learning theory and Ausubel's meaningful learning theory all show that the integration of Geometric Sketchpad and junior high school mathematics is necessary.Secondly,the integration design of Geometric Sketchpad and Junior High School Mathematics Case is mainly from two aspects of function and geometry,in order to reflect the advantages of the integration of Geometric Sketchpad and MathematicsTeaching.Thirdly,the case will be tried through the open class activities organized by D school,so that more mathematics teachers can feel the impact of geometry Sketchpad on teaching.Fourthly,through student questionnaires and face-to-face interviews with teachers,we can understand the impact of the Geometric Sketchpad on teaching and students' expectations of the application of the Geometric Sketchpad in teaching and teachers' views on the integration of Geometric Sketchpad and mathematics.The results show that the functions of precise drawing and dynamic display of geometric sketchpad have played many positive roles for both students and teachers.For students,precise graphics are conducive to students' observation and analysis of graphics,cultivating their precise logical thinking,the combination of numbers and figures and the ability to solve problems;for teachers,it is convenient to solve abstract knowledge and dynamic knowledge.At the same time,it saves the drawing time in class and increases the students' thinking time in class.
