In this paper, we explore how co-design creates opportunities to learn practical design knowledge related clarifying and balancing goals for a particular class of contexts: developing materials that meet ambitious, externally defined disciplinary learning also connect the interests priorities students from minoritized groups communities. University-based researchers, classroom teachers, distric...

New continuous group transforms, together with their discretization over a lattice of any density and admissible symmetry, are defined for a general compact simple Lie groups of rank 2 ≤ n < ∞. Rank 1 transforms are known. Rank 2 exposition of Cand S-transforms is in the literature. The E-transforms appear here for the first time.
