Subscriber Updates - AP Worksheet Upgrade Completed

One month ahead of schedule the AP Worksheet upgrade has been completed. All subscribers should find the new AP Worksheet package in their subscriber areas.

In the final analysis, the AP Worksheet package actually came out at 94 worksheets plus the appropriate answers. For full titles of the worksheets and their relationship to the old package, please see this document; http://www.adriandingleschemistrypages.com/overhaul.pdf

A major overhaul like this one is unlikely to come without a few hitches, so PLEASE inform as soon as you encounter any issues. If I do not know about them, I cannot correct them.

My latest writing project

In conjunction with Applied Practice, Dynamic Wordworks and Series Editor David Emmerson, I have written a series of AP Chemistry materials aimed at AP exam preparation in the classroom. The books are categorized into a series of topics and consist of AP style multiple-choice & free response questions. The first four books in the series are now available for purchase and I am in the process of writing the fifth. I am confident that these can be a GREAT resource for AP Chemistry teachers who are seeking to improve their students’ understanding, and with it their performance in the AP exam and in turn their AP scores.

In addition to the seventy-five multiple-choice questions and six free response in each book, you will also find a glossary, teaching notes and strategies for success. All questions come with full answers with multiple-choice questions come with explanations.

The recent fuss over units of “kJ per mole of REACTION” on 2007, 2

Having analyzed all of the comments (both off and on the AP listserve) in regards to this matter, the following are perfectly clear to me;

1. James Spencer’s article actually makes a decent argument for using the “kJ per mole of reaction” in TERMS OF CHEMISTRY and the units of Delta G. For the record I don’t like it much, but if I had to live with it I would.

2. This concept is NOT being used with ANY kind of regularity amongst common AP texts nor in AP classrooms across the country. MANY, VERY experienced teachers are simply not on board with this nomenclature. As a result, to say this is potentially confusing to candidates is a HUGE understatement.

3. #1 notwithstanding, the College Board/Test Development Committee has made a serious error here by NOT introducing the relevance of this concept to the exam in a MUCH, MUCH, MUCH bolder way. ANOTHER horrible effort at communicating with those of us on the ground.

4. #3 is EXACTLY the same kind of error that the CB/TDC made when not properly introducing examples for the new question #4 format - that was a shambles, so is this. There appears to be a disconnect between the TDC and the teachers.

In summary, there may not necessarily be any problem with the chemistry in this instance, and in that respect I disagree with some of my more upset colleagues, but you simply cannot conduct public examinations and standardizing testing in this manner.
