Reflections on a Year of AP

As I write this, it is the day before the national AP Chemistry exam.  We’ve been working toward this day since August.  We’ve endured late hours, broken crucibles, anxiety, and tears.  I’ve run weekend and evening review sessions, we’ve taken practice tests,

What are they thinking? Where did they get that idea?

Making Thinking Visible

Have you read “Making Thinking Visible”?  You should. It focuses on making student thinking visible to the teacher. While still learning to use the visible thinking routines, I really feel more conscious of students’ understandings than ever.  

Here is a sample activity that I adapted to fit my honor chemistry students’ needs:

The HaberFilm.com website is a helpful resource for teachers that have interest in using the Haber video in their curriculum. Reading materials and lesson ideas are available. I recently used a lesson that my colleague created directly from the provided materials. You can check out that lesson here. The lesson included some background reading, viewing the video, participating in an excellent discussion and a follow up writing assignment.

Representing the Macroscopic, Particulate, Symbolic, & Real World Representations of Chemical Reactions.

Fri, 04/10/2015 - 15:57 -- Doug Ragan

 Last year while attending the Biennial Conference on Chemical Education at GVSU I had the opportunity to hear a talk that showed a video of a chemical demonstration showing the burning of magnesium metal.  We have all seen many of these videos (thank you YouTube) and probably have performed this demo for our own students many times.  During the video it may have been represented with a chemical equation followed by the students being asked to balance the equation or maybe even predict the products.  Although the use of video including the showing of the equation nicely represents the macroscopic and symbolic representation, what was so unique about this particular video is that it also included the particulate representation embedded on top of the video of the demo.   This was the first time I had seen the particulate level representation done like that and so I was intrigued in wanting to find more of these representations.
