“…While teaching and learning science and mathematics in a non-native language can threaten the cultural identity and undermine the local language (Ennaji, 2005;Lodge, 2016;Robertson & Graven, 2019;Sah, 2020;Sah & Li, 2018), it can, on the other hand, contribute to the advancement of an individual's socioeconomic mobility domestically and internationally (Albury, 2019;Piller & Cho, 2013;De Swaan, 2001) without having a negative impact on the cultural identity and the value of the native language in the society (Cummins, 2000;Navés, 2009;Ngugi, 1994;Sumaryono & Ortiz, 2004). Furthermore, while some researchers perceive teaching and learning science and mathematics in a non-native language as an opportunity for students to achieve the aspects of science and mathematics literacy (Kuteeva & Airey, 2013;Sandström et al, 2013), other researchers argue that the lack of proficiency in the non-native language, as the language of science and mathematics instruction, can hamper the learning of these subjects (Heliawati et al, 2020;Hu & Gao, 2020;Kibirige & Mogofe, 2021).…”
