Inquiry For AP Chemistry

Tue, 07/16/2013 - 19:29 -- Deanna Cullen
Vegas 2013 AP

I attended and presented at the National AP Conference in Las Vegas on July 18th and 19th! Adding Inquiry to the course is one of the major changes to how we will teach AP Chemistry.  I shared some resources and gave tips during my presentation. I am sharing those resource in this post.  I am also sharing items that I found especially helpful from presentations that I attended and conversations I had with other teachers.

Next Generation Science Standards

If you haven't seen them yet, check out the final release of the Next Generation Science Standards. There is helpful information at the site.  My home state of Michigan is currently asking for public input in order to plan support for implementing NGSS.

Publishing Your Work

Thu, 04/18/2013 - 18:46 -- Deanna Cullen

Whether it is a completely unique idea or just a twist on an old classic, engage in collaboration with other chemistry teachers around the world and publish your work. There are many venues and the pool of precollege chemistry instructors that are already contributing is relatively small.

NSTA Activities

Avogadro @ NSTA 2013

At NSTA (in beautiful San Antonio, Texas), this past week, I shared activities designed to explore three levels of representation AND provide formative assessment techniques to reveal student misconceptions. All of the activities shared have been featured in the Journal of Chemical Education or have been linked to research articles in JCE as supporting information.

Stoichiometry Resources

Mon, 02/18/2013 - 12:45 -- Deanna Cullen
Limiting PhET

Moles, mole ratios and stoichiometry have been frustrating topics for many of my chemistry students. The MOLE and Avogadro’s number get tangled up in other Chemistry jargon and students have stared at me like I am speaking another language. I have been around long enough to know this is a problem that many of us have faced. I have tried many ideas that have helped and I want to share a few.

Percent Composition of an Oreo Cookie

Wed, 01/16/2013 - 14:09 -- Deanna Cullen

Whenever possible, I try to begin a topic with something my students are familar with. For the introduction of Percent Composition in my general chemistry course, I brought in bags of Oreo cookies. Seeing the bags upon entering class was a great attention getter. If you are looking for ways to add more inquiry to your chemistry course, this a an example of how you can experiment with giving up a little control. Try it and see how it goes.
