Hara, Tomoki; Ahara, Kazushi – International Journal for Technology in Mathematics Education, 2020
GeoGebra is the most well-known Dynamic Geometry Application (DGA) in the world. Many researchers are interested in GeoGebra as a tool to make interactive mathematics resources. Here we focus on a snapping function in GeoGebra, which is a kind of general feature of DGA: the mouse cursor is attracted to a specific position or a specific object and…

Cavicchi, Elizabeth – New Educator, 2009
A teacher narrates from activities and discussions that arose among undergraduates and herself while doing critical explorations of mirrors. Surprised by light's behaviors, the students responded with curiosity, losing their dependence on answers as the format of school knowledge. Inadequacies in how participants supposed light works emerged in…

Howson, A. G.; Westbury, Ian – 1980
An attempt is made to define the meaning of invention and innovation in mathematics education in order to help develop guidelines for policies of research and development in this area. Spectrums of invention in the realms of geometry and group theory are proposed as models of ordering understanding of creative activity within mathematics. This…

Pokay, Patricia A.; Tayeh, Carla – Computers in the Schools, 1997
Based on a college-level geometry course, presents practical suggestions for integrating exploratory computer applications into the mathematics classroom. Reveals that students need more experimental time with technology to reduce anxiety, and assessments need to be developed and implemented to tap the outcomes of problem solving and higher level…

Pech, Pavel – International Journal for Technology in Mathematics Education, 2005
Computer algebra methods based on results of commutative algebra like Groebner bases of ideals and elimination of variables make it possible to solve complex, elementary and non elementary problems of geometry, which are difficult to solve using a classical approach. Computer algebra methods permit the proof of geometric theorems, automatic…
