I hesitated to join Twitter because it seemed like "just one more thing to add to my plate".  I did finally log on and created an account.

In my grad program one of our discussions concerned how to teach science the way science is actually done.  This seems to be one of the core ideas in the Next Generation Science Standards.  The standards want to encourage students to think more like scientists and engineers as opposed to students seeking an A.  Please share your thoughts!

As the trimester comes to an end, I have the chance to reflect with my chemistry students and ask them about course likes and dislikes.  A major "like" that came out was the use of the Expo brand neon markers.  I had heard about their use from Brian Bennett @bennettscience and how well they show up on the black lab tables.
