Unlike communities of practice, previous studies on imagined communities of practice are scarce, yet enlightening. The present research was conducted in an English as a foreign language (EFL) context in order to provide more insight into how language learners perceive their imagined communities (ICs). It was based on Norton's (2000; 2001) conceptualization of ICs which connected the notions of imagination and imagined community to second language (L2) learning and classroom practice. To this end, 945 male and female EFL learners from different cities in Iran belonging to different age groups and language proficiency levels were recruited for this study. The instrument for data collection was a validated 57-item questionnaire. The findings of the study showed that the participants possessed a moderate level of investment in their ICs. Moreover, t-test results indicated that there was a significant difference between male and female learners in the extent of investment in their ICs. Furthermore, the significant differences in the extent of investment in ICs were shown between teenagers and adults and between learners in low proficiency (LP) and high proficiency (HP) groups. These findings contribute to more in-depth understanding of language learners' ICs in an EFL context. Pedagogical implications of the study are discussed and some suggestions are made for future research.
