"So according to our "big tent" model of PBL, some of the newer "X-BLs" -- problem-, challenge- and design-based -- are basically modern versions of the same concept. They feature, to varying degrees, all of BIE's 8 Essential Elements of PBL, although each has its own distinct flavor. (And by the way, each of these three, along with project-based learning, falls under the general category of inquiry-based learning -- which also includes research papers, scientific investigations, Socratic Seminars or other text-based discussions, etc."
This article confirms the importance of the transition process to new programs. Even when the new program has great advantages, it is important to prepare both students and parents for the change and challenges found in "deeper thinking" processes.
"MathleteBlogs.com is a resource for mathematics teachers to connect their math students with peers from around the globe to enhance their mathematical learning experience from K-12."
Here is a list of people who blog about mathematics from David Wees (as a Google Reader bundle), or mathematics education. It is incomplete... but will get updated periodically.
Creating learning situations that encourage transfer of knowledge
Two vital lessons.1) Transfer is the bottom-line goal of all learning, not scripted behavior.
2) Transfer means that a learner can draw upon and apply from all of what was learned, as the situation warrants, not just do one move at a time in response to a prompt.
