Having recently joined a major world-wide IT company that strongly uses and defends agile methods for development projects, I got my self thinking: what if we try to apply agile concepts for the educational scenario?
For instance, my team does daily stand-up meetings, where each member of the team talks about whatever tasks he did for the project in the last 24 hours, pointing out difficulties that could warrant help from others; in education, we could have multiple students assigned different tasks, and have they quickly elaborate on what have they learned and what are they struggling with, so that the other students and the teacher may help him. We could also copy the idea of pair programming, and have students pair up randomly to complete their tasks on a daily basis, so as to foster cooperation and communication skills.
Sure, we would still need some measure of actual lecture being given by the teacher/professor, but more focus should be given on teaching students to build their knowledge by their own research. I think that most of the time the teacher should be going rounds around the class to help students and assess their progress. Alike agile, everything should be continuously tested; instead of big, stressful exams every two months or so, students should be able to demonstrate their acquired knowledge - both orally and in written - on daily basis.
All of this may sound a bit alike constructivist method, but I want to avoid that road; in my opinion, constructivism's exaggerated leniency/freedom is a recipe for disaster; my approach would have the teacher in a stronger guidance position (such as a project manager), closely watching the group's performance and enforcing a pace. The concept of a student failing should still exist, and should actually be much more common than currently, making it less traumatic; as in agile, we have to fail fast: advancement cycles could be MUCH shorter (think a fortnight), and a failing student should be brought to some reinforcement class on the specific subject he is behind.
