A while back I scooped two posts from Grant Wiggins, "Everything You Know About Curriculum May Be Wrong. Really." and "Rethinking Curriculum Writing, Part 2." This post is Wiggin's response to replies he received on the two posts mentioned above.
A variety of issues are raised and addressed. He discusses Problem Based Learning (PBL) stating "many PBL courses are quite weak in the sequencing of problems and the lack of focus on transfer. Similarly, Project-based learning is often haphazard and poorly-designed: it often is just a bunch of random projects in no particular sequence..."
He also brings up the Understanding by Design and describes how you can take diverse subject matter and create amazing results.
If you read the first of this series I would urge you to read this post, and if you have not, search on Grant Wiggins and you can find his first two essays on Curriculum.
For sure when using the experiential method of teaching and learning, the teacher must emphasize what areas of the teaching/learning process the learners must master and transfer or otherwise the learners might simply take the learning for granted.
We must link learning to student passions to make hands on minds on.
