Welcome to the Fall 2022 issue of GeT: The News! Download the PDF here.

In this issue, Amanda Brown shares a call for chapter proposals for a forthcoming book on GeT courses. Amanda, on behalf of her co-editors (Pat Herbst, Nat Miller, and Laura Pyzdrowski), requests that newsletter readers spread the word to potential  chapter contributors. 

Steve Szydlik assesses some of the affordances and challenges of utilizing hyperbolic geometry within a GeT course, explains the link of Euclidean constructions and hyperbolic models, and provides ways to explore these hyperbolic models with Geogebra. Christopher C. Tisdell discusses the potential of a circle arc template to replace the traditional compass in the learning and teaching of geometric constructions within schools. Sharon Vestal, Orly Buchbinder, and Tuyin An explain their project which aims to explore the question: “How and to what extent does engaging GeT students with the FullProof software affect their competence with, and beliefs about geometry proofs?” 

Pat Herbst announces a new working group: Engaging with the Student Learning Objectives (ESLO). Julia St.Goar updates us on the Transformation Working Group’s focus over the summer as well as what the group will be focusing on for the fall. Nat Miller announces the first public version of the Student Learning Objectives (SLOs) and tells us what the group will be continuing to work on. 

Our community spotlight features GeT instructor Mara Markinson. Also included in this newsletter are the upcoming seminars.

We welcome contributions from members of the GeT: A Pencil community! Activities you tried in class, things you observed your students do, reflections on your experience teaching, thoughts on what the GeT course should include . . .  any of these and others would be fair game to write about. Consider the length of the articles in this issue as examples of how long your piece could be. To pitch your idea, email us at
