In Lebanon, science is taught in an international language (French or English) based on a language-in-education policy rooted in Lebanon's colonial history. Given the intersection among social/socioeconomic class, educational equity, and science performance, learning science in a language other than one's own raises concerns around…

Language is a contextual factor of an education system as it determines the Language of Learning and Teaching (LOLT).

The "optimism hypothesis" claims that immigrant students do better in the Norwegian education system than their socioeconomic status would suggest, due to the strong educational aspirations that immigrant parents might have for their children. Grounded in an educational equity paradigm, this study aims to test this hypothesis by…

The language used as a medium of instruction (MOI) has implications for learning outcomes. In most African classrooms, an international language is solely or dominantly used as an MOI.

We explore the impact of the language of instruction on academic performance of Arabic-speaking students who are expected to learn mathematics and science in and through a second language (L2).
