A post with embedded photos

Barb and I visited Maroon Bells last weekend. The aspens were a blaze of yellow. Here's an example of that:

It's especially cool when you see the ones with a red-orange tinge.

As another test, here's a png with some transparency at the right. It's a free-body diagram for a Physics homework set we wrote this week. This text is just for filler... what to write? From my paper: Since the pioneering work of Piaget [1] in the 1970's, constructivist theories of learning have prevailed in educational research. It is generally agreed that students must construct their own understanding as active sense makers within their framework of existing knowledge [2]. Yet the implications of constructivism for instructional technique have been not been so clear. The most direct (perhaps naïve) applications of constructivist ideas have taken the form of discovery learning, in which students receive minimal guidance and discover the important principles for themselves. But there remains a paucity of research supporting pure discovery methods [3] and critics charge that constructivism has become ideological, leading to the use of pure discovery when it may be inappropriate. Oh yea.
