Many educators hail active learning as a solution for helping undergraduate students acquire a variety of essential skills that are needed in today's workplace and which cannot be acquired through traditional learning methods (e.g., collaboration, communication, creativity, complex problem-solving). If this is the case, then why aren't more universities steeped in undergraduate courses that are project-based, problem-based, inquiry-based, and so forth? Why do we see in so many universities the majority of undergraduate courses being delivered in more or less the traditional lecture-and-recitation style? From my experience, the reason for sticking to the traditional style of instruction at universities often has little to do with available budget or with the ratio of instructors to students. It also has very little to do with the claim that only through the traditional approach can we teach fundamental concepts (it may surprise you to hear, but I've heard that reason from faculty). The main reason I see for not implementing active learning is that this approach requires a level of pedagogical proficiency that traditional learning doesn't. And most faculty/instructors don't have that level of pedagogical proficiency, as they are simply not being incentivized to acquire it. What matters to their career success are publications and funding.
What are your experiences and thoughts on the reasons active learning isn't implemented more in undergraduate education? And what can be done about it?
