This spring, the transformation group is meeting every other Wednesday at 11:00 AM EDT and has been particularly focused on disseminating results. In February, several members of the transformation group presented a contributed paper titled “GeT Lesson Study: Engaging Prospective Teachers in Defining Mutuality” at the SIGMAA on RUME conference (Boyce et. al., 2023). Additionally, the group is working on writing two potential chapters for the upcoming handbook The GeT Course: Resources and Objectives for the Geometry Courses for Teachers. One potential chapter relates to ways in which transformation geometry can be axiomatized and brought into a GeT course in a rigorous way, while also being adaptive to the wide variety of contexts in which GeT courses are taught. The other potential chapter relates to the work presented at the RUME conference above, which focuses on a lesson featuring Adinkra originating from Ghana (Eglash et. al., n.d.) as well as concepts relating to transformation geometry. This semester, two members of the transformation group have further modified the “Adinkra” lesson and taught these modified lessons in their own classes. The group is engaging in further analysis of data collected from these and previous iterations of the lesson. Work on this “Adinkra” lesson has become such a significant focus that many members, under the leadership of Steven Boyce, have chosen to meet every-other-week, alternating with the “main” transformation meeting time, to have additional time to focus on work surrounding this lesson.
