The present study examined factors contributing to motivation of young EFL learners. Specifically, it explored learners’ attitudes and purposes for studying English, and how their perceptions of social support (teacher, family, peers) and that of the formal learning environment (learning tasks and class activities) varied at different levels of motivation. In total, 23 grade six students who studied at a Macau primary school completed a 10-item open-ended questionnaire. Findings revealed that most of the participants were highly motivated and learned English for both instrumental (e.g., for work and travel) and integrative (e.g., wanting to integrate within the target language culture) reasons. Most respondents reported that they viewed their teachers positively, which may explain why most of them also had a positive view of studying English despite indicating that their family expected them to get high grades on exams, and that most of their classmates perceived studying English negatively. Unsurprisingly, participants also reported that games and songs were their favored activities because they increased their intrinsic motivation to learn. The results of this study suggest that young learner motivation may be largely influenced by the learning environment (as opposed to family or peer social relationships), notably the positive relationship with the teacher and the types of learning activities employed to achieve learning aims.
