Online learning platforms have exploded in popularity, but do they really deliver better outcomes than traditional classrooms? I've taken both types of courses for my data science certification, and the flexibility of the online format was unmatched, yet I missed the spontaneous discussions. From my experience, online courses worked best for structured material like coding, but struggled with subjects that need nuanced debate, like ethics. So, I think the verdict depends more on the subject and learner than on the medium itself.
