Furner, Joseph M.; Marinas, Carol A. – EURASIA Journal of Mathematics, Science & Technology Education, 2007
This paper discusses insights for using geometry sketching software to teach geometric concepts for kindergarten to grade 4. The authors created hands-on resources that incorporate technology in a user-friendly environment. When working with "Geometer's Sketchpad" with middle and high school students, the teacher educators noticed the…

Shaffer, David Williamson – Wisconsin Center for Education Research (NJ1), 2005
This paper examines how middle school students developed understanding of transformational geometry through design activities in Escher's World, a computationally rich design experiment explicitly modeled on an architectural design studio. Escher's World was based on the theory of pedagogical praxis (Shaffer, 2004a), which suggests that preserving…
