Investigation sequences in dynamic geometry for a GeT course: the case of similarity
Summary: In this talk, I will describe a sequence of investigative activities in dynamic geometry (Geometer’s Sketchpad) developed and enacted in a Geometry course. The specific example of investigative sequence will focus on similarity theorems from Euclidean geometry perspective. While all students can benefit learning Geometry from inquiry-based perspective, this approach may be particularly appropriate for prospective teachers, for whom it can serve as a model and inspiration for their future classrooms.
Duration: 60 minutes
Format: Online seminar via Zoom web meeting software with questions and discussion. Detailed instructions for joining the seminar will be emailed to registered participants.
