Just had a great workshop with Dave Ballard rom Tauranga. While the content was specifically Maths/Science/Geography the idea behind it was validity. Validity of the problem being investigated. I have a real struggle making problem solving real-world enough in my classes. In the world of psychology this is called "Ecological Validity" - does the problem mimic a real world setting?
Well Dave's presentation was just that. Using a resource from the Port of Tauranga here Dave talked us through a navigation problem using pencil & ruler, calculator, computer, tables, a whole gamut of resources (great for different kinds of learners). It had the feel of a truly "inclusive" lesson (or more probably a unit of work).
