This study aimed to examine the pre-service teachers’ (PSTs) learning experiences of international teaching practicum (ITP) in Indonesia. The researchers employed a case study research design and the participants comprised three female PSTs majoring in Mathematics from a Malaysian public university who undertook the ITP in a public junior high school in Indonesia for eight weeks. The data were collected from the PSTs’ reflective journals and face-to-face interviews which were analysed using the Interpretative Phenomenological Analysis. The findings revealed four major themes of their learning experiences of ITP, namely mathematics lesson planning, mathematics teaching and learning, guidance from mentor teacher and contributions to the school. The study indicates that ITP could be an alternative platform for PSTs to gain positive learning experiences and prepare them for the challenging teaching environment in the times of globalization
