To all who are looking for aids for the assessment,
Let me suggest 2 things:
1. You will have to have knowledge about all 4 sciences, Earth Sci, Biology, Physics, as well as Chemistry. You will have to know the other sciences as they relate to your chosen field (in this case chemistry). It's pretty basic stuff, but may require some review. So. . .
I picked up a book from each subject area and made a copy of the National Science Standards. I reviewed the relevant chapters in each book. I started with the chapter summaries at the end of each chapter. If I knew all the info, I stopped there. If I needed more info, I read in the chapter. Again, ONLY the stuff in the Nat'l Science Standards. I did like the Campbell Biology book for Biology.
2. Go to www.nbpts.org/candidates/ckc.cfm and click on View All Scoring Guides. Find the AYA Science one. Go to the end of the book. The very last section is composed of 2 parts. These are previous years' prompts taken from the actual assessments. I would time myself for 30 minutes and sit at the computer and answer as much as I could in that time so I could get a feel for what would be required. Then go back to the Scoring Guide to the rubrics pages and figure out where you think you are in the way of a score. (Other candidates from last year told me that this was very helpful and practical to do.)
It would help me also if one of you (if you are in Florida) could just send me a quick note indicating that you are a FL teacher. I could count it towards my mentoring hours. If not, it's still good advice and I am glad to be able to help you. Good luck.
