Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

The purpose of this study was to develop and validate a survey of opportunities to participate (OtP) in science that will allow educators and researchers to closely approximate the types of learning opportunities students have in science classrooms. Additionally, we examined whether and how opportunity gaps in science learning may exist across…

Critical consciousness represents the analysis and critique of structural inequalities, the motivation and perceived capacity to effect change, and social action to redress inequity. A wave of recent instruments measuring critical consciousness have been rigorously validated. Yet, whether these measures efficiently assess different levels of…
