Research On Strategies Of Assisting High School Solid Geometry Teaching With GGB

Based on the continuous development of information technology under the background,multimedia information technology has shown its unique advantages in the mathematics classroom.At the same time,the content of high school solid geometry also puts forward further requirements for students’ mathematical core literacy,and more and more mathematical software has been chosen by mathematics teachers to assist in teaching.GGB is a powerful and easy-to-use free dynamic drawing software.Its unique 3D drawing demonstration function can visually show abstract space geometry to students,thus achieving effective teaching.GGB software can be used for dynamic demonstration,when necessary,which not only reduces the teaching difficulty of teachers but also reduces students’ cognitive load and improves their spatial imagination.However,in practice,there are a series of problems,such as teachers’ lack of understanding of GGB software,infrequent use,and ineffective use.Only when these problems are solved can the effectiveness of GGB software-assisted stereometry teaching be truly implemented.Initially,the research background of this paper has been described,with the significance of the research and its contents and methods analyzed.Then,by using the literature research method,the current research status of GGB software-assisted teaching at home and abroad was sorted out.Moreover,the concepts related to solid geometry,GGB software,and the theories of mathematical multiple representations,nearest developmental zone theory and computer-assisted instruction based on this study are also outlined through the literature research method.Furthermore,mathematics teachers and senior students of Yan’an Experimental Middle School are selected as the subjects of the study.The questionnaire method is applied to investigate the students’ difficulties in learning cubic geometry and their current level of thinking about cubic geometry.Meanwhile,the interview method is applied to investigate the teachers’ teaching status when teaching stereo geometry,the practical application of using dynamic teaching software and the learning of mathematical theories to provide a factual basis for the subsequent research on teaching strategies.Finally,the strategy of applying GGB software to high school solid geometry teaching is proposed through the action research method,which is mainly divided into two aspects:the preparation strategy before teaching and the implementation strategy during the teaching process.Based on the strategy,two typical teaching cases are designed based on the current teaching situation.
