Hi Karen: To some degree, good teachers are always trying out new techiques or introducing new approaches. I think when it's successful, we planned well. But misses are important too - they allow us to examine what could be improved or why did we not connect. I would rather try and fail than provide boring, "same-old" delivery instruction. We really ought to facilitate learning, rather than provide it. This means experimenting with how we can get the student to participate in their own learning. It does some require some degree of trial and error. Regards, Barry
