“…While the literature review also underscored how researchers have explored learning materials developed by teachers, most of the studies focused on in‐service teachers (e.g., Choi & Lo, 2022; Howard & Major, 2004; Li et al, 2021; Yuniarti, 2019) and paid little attention to how preservice teachers developed materials (e.g., Carabantes & Paran, 2022; de Laurentiis Brandão, 2018; Sert & Li, 2017; Usta & Güntepe, 2017) or how teacher educators evaluated these materials.

The second author felt these principles could be harnessed as a conceptual framework for developing an evaluation tool for use in his classroom.…”
