For me this is evidence enough to convince me that PBL is the best way to learn and remember things - to store it in the long time memory. This facts back up the ideas that as a student it's very important to use as many senses as possible (the information is stored all over the brain). It is of great importance to use as many situations and occasions as possible to discuss, reflect and exchange information (remember: memory is a constant work-in-progress!) with each other. And as a student also has the possibilities to ask questions and to make conclusions of whatever you study. As you see in the last section above, it is of great importance to get as many associations and experiences as possible. This will create a relative reliable memory and a good "learning for life" knowledge. Or to learn a good learning behaviour. Earlier I also wrote something about that it takes about five to eight hours to create a LTM. And that is exactly what PBL promote. You start with a "real-world" problem; the student gets associations (from their own personal experience); which give situations to look for information and discuss it; which give source to new associations and maybe new problems to solve and so on. You strike the problem over and over again. The learning process becomes a constant work-in-progress and that will make it easier to encode something in the LTM. And to create an LTM in the students brain is the most important thing to do as a teacher!

Do you look for some good links about what PBL really means to you as a student or as a teacher? Here I give you some examples:
