动态建模和 3D 设计技术的兴起为数学教师提供了诱人的机会，让他们重新考虑数学教育中的许多教学问题，从动机到应用，从可视化到物理操作。本文报道了一项有关立方体旋转的课堂教学实验，该实验结合了传统工具、GeoGebra (www.geogebra.org) 以及 3D 设计和打印技术。它强调了有价值的数学任务与战略性使用多种技术之间丰富的相互作用，以维持与一群未来教师的意义建构和问题解决。
The rise of dynamic modeling and 3-D design technologies provides appealing opportunities for mathematics teachers to reconsider a host of pedagogical issues in mathematics education, ranging from motivation to application and from visualization to physical manipulation. This article reports on a classroom teaching experiment about cube spinning, integrating traditional tools, GeoGebra (www.geogebra.org), and 3-D design and printing technologies. It highlights the rich interplay between worthwhile mathematical tasks and the strategic use of diverse technologies in sustaining sense making and problem solving with a group of prospective teachers.
