This week our task was to choose a problem of practice and illustrate how a digital tool would address the problem. The problem of practice I chose to address in my geometry classroom is classifying and proving quadrilaterals. I believe this is an ill structured problem because there are several important variables that need to be considered, in context, at the same time. That is, students must make connections to prior learning and using reasoning skills to formalize definitions, make conjectures, and write proofs. In the screencast below I will show how using the interactive math software, Geogebra is much more effective for teaching quadrilateral properties and how it allows learners to explore more diverse learning scenarios.
