许多现行标准要求本科数学教师从转换的角度促进未来教师的几何学习,这标志着与以前标准的变化。这种情况的新奇意味着它是不清楚的,从转换的角度来看,在本科生的学习和几何教学。为了解决这个问题,我们说明了如何具体的课堂活动和设计原则可能会帮助未来的教师之间的概念联系一致的证明和变换的方法几何。此外,为了向教师说明这些活动,我们提供了未来教师对其中一些问题的工作的例子。
Undergraduate mathematics instructors are called by many current standards to promote prospective teachers’ learning of geometry from a transformation perspective, marking a change from previous standards. The novelty of this situation means it is unclear what is involved in undergraduate learning and teaching of geometry from a transformation perspective. To approach this problem, we illustrate how specific in-class activities and design principles might help prospective teachers make conceptual links between congruence proofs and a transformation approach to geometry. Additionally, to illustrate these activities for instructors, we provide examples of prospective teachers’ work on some of these problems.
