Brakoniecki, Aaron; Amador, Julie M.; Glassmeyer, David – Contemporary Issues in Technology and Teacher Education (CITE Journal), 2018
Dynamic geometry software can help teachers highlight mathematical relationships in ways not possible with static diagrams. However, these opportunities are mediated by teachers' abilities to construct sketches that focus users' attention on the desired variant or invariant relationships. The study described in this paper looked at two cohorts of…
