What is active learning?

Active learning is a teaching approach that engages students directly in the learning process through activities and discussion, rather than passively receiving information from a lecturer. It often involves problem-solving, group work, or hands-on activities that encourage critical thinking and deeper understanding. In the context of machine learning, active learning refers to algorithms that interactively select the most informative data points to label, improving model performance with fewer labeled examples. Both uses of the term aim to make learning more efficient and effective by focusing on engagement and targeted effort.
