信息技术在立体几何课堂教学中的有效应用

Effective Application of Information Technology in Classroom Teaching of Solid Geometry

高中立体几何运算突出了几何直观与代数运算之间的融合,培养学生运用直观想象、推理论证、度量计算等学科方法来认识和探索空间图形的位置关系及性质。由于其涉及的知识逻辑性和空间思维很强,在实际教学中学生常因缺乏空间想象能力难以把握问题本质。而运用信息技术整合立体几何课堂教学,可以让学生真实体验问题情境,直观地观察空间问题的本质,帮助学生突破课堂的重点和难点,由此提升了学生数学核心素养,激发学生积极思考、勇于创新的科学精神,增强了学习数学的信心和兴趣。可见,信息技术在立体几何教学中的有效应用,促进了师生教学方式上的变革。

High school solid geometry operation highlights the integration between geometric intuition and algebraic operation,and trains students to understand and explore the position relationship and nature of spatial graphics by using such disciplinary methods as intuitive imagination,reasoning and demonstration,and metric calculation.The knowledge involved in solid geometry is very logical with strong spatial thinking,and students often find it difficult to grasp the essence of problems in practical teaching due to a lack of spatial imagination.However,teaching by using information technology to integrate the solid geometry classroom allows students to experience the real problem situation,visualize the nature of spatial problems,and help students break through the important and difficult points in the classroom,thus improving students’core mathematical literacy,stimulating students’positive thinking and innovative scientific spirit,and enhancing their confidence and interest in learning mathematics.It can be seen that the effective application of information technology in solid geometry teaching has promoted the reform of teaching methods for teachers and students.
