This article reports on a qualitative study conducted at primary schools in Hong Kong exploring the use of microlearning to support the self-directed continuing professional development (CPD) of English language teachers. Microlearning refers to short, concise, and easily consumable segments of learning about a knowledge point or skill. These activities tend to be multimodal and delivered through digital platforms, making them accessible anytime and anywhere. Currently, little is known about teachers’ perceptions of microlearning. To address this gap, we developed and delivered a mobile course that followed a microlearning approach and covered various aspects of digital technologies and English language teaching. Eight primary school English teachers engaged in the course and shared their perceptions of the experience in semi-structured interviews. The findings suggest that they found microlearning to be more enriching and conducive to developing their digital competence than traditional CPD. It allowed them to address their immediate needs, develop practical skills, and integrate technology into their practices. The study provides important insights into the use of microlearning to support self-directed CPD. Copyright © 2024 The Open University.
