This descriptive classroom-based study involved a group of 25 pre-service teacher participants from the Master's program in Teaching English as a Foreign and Second Language (TEFL) at the Complutense University in Madrid (UCM), Spain. The participants were approached in their threefold facet as graduate students, classroom active debate leaders, and prospective teachers. We aimed to explore what they perceived to be the benefits and drawbacks of using multimodal learning objects (LO) as learners, active classroom debate leaders and pre-service teachers of English in contexts of inverted classroom instruction. The results showed that LO were perceived as an excellent tool in inverted settings of instruction as they enabled a shift in the classroom dynamics towards a learner-centred approach. No significant differences were found among the views of students, debate leaders, and pre-service teachers. However, pre-service teachers expressed concerns about implementing LO. This suggests that more importance should be given to support their use in the English classroom.
