Microlearning is an academic concept and methodological approach within educational science and instructional design. It investigates the principles, design, delivery, and effectiveness of learning experiences structured into small, focused units typically characterized by brevity, singularity of topic, and specific learning outcomes, often employed to facilitate flexible, just-in-time, or continuous professional development. Its significance lies in its potential to align with modern cognitive patterns, address constraints of time and attention, and enable scalable knowledge acquisition in diverse digital and organizational environments.
