Motivations for primary school students to participate in English classes are important for educators in areas that consider English as a foreign language (EFL). Although there is a lot of research discussing how to motivate non-native English-speaking children to participate in sessions, there is little study making an effort to find out what motivates primary school students in EFL regions to engage in their English classes despite their relevance. However, there is still a lack of specific studies, so this is a systematic review of previous studies about motivations for those students to participate during online and in-person sessions because of the limitations of previous literature. By reviewing previous research, this paper finds that both external and internal motivations have an influence on the engagement of EFL primary school students during in-person English sessions. For intrinsic motivations, reward plays an important role in motivating EFL primary school students to learn English. However, students can be influenced by different kinds of motivations at the same time.
