Subclaims¶

q2 i? MAET of students exploring parallel-lines conjectures in shAR captured body movements and positionings—moving between lines, tilting heads, standing on tiptoes—suggesting scale, representation positioning, and body positioning are design considerations. → Walkington 2024

q2 · i? · theoretical · r3

Qualitative MAET case of two high school students using Microsoft HoloLens 2 holograms of parallel lines cut by a transversal, rendered at near eye-level and larger than the students. The authors note this larger scale may allow for new types of mathematical exploration, citing Dimmel et al. (2021).

"This MAET allowed for important observations about how scale, the positioning of the representation, and body positioning may be important design considerations in our context"
