Pirates, Textbooks, and Drugs

Hi,

Bloom's Taxonomy according to Pirates of the Caribbean : http://www.youtube.com/watch?v=qjhKmhKjzsQ .

I've been told that, in order to progress in learning a new programming language, I have to memorize an exact sequence of commands even though I don't understand it. My brain hurts, so it started to wander around on its own and found some more stuff. Now I know what my students in Chem12 must feel like.

This series has a bit of a theme going. First is a New York Times article :
http://www.nytimes.com/2010/08/01/technology/01ping.html?_r=1&th&emc=th. The article is on textbooks, and comparing purchasing textbooks, or using readily available Internet resources and essentially make your own free textbooks. The 'Curriki' (free website) is here: http://www.curriki.org/xwiki/bin/view/Main/WebHome. The article makes the point that "2+2=4" for quite awhile, and writing and re-writing textbooks for the sake of purchasing new ones doesn't make much sense. In Chemistry (11 & 12) we have two textbooks - one's essentially a workbook, and another for background material in case the lecture doesn't quite cut it for explanations. I could easily see online materials taking up the roles of the latter - reaction kinetics is unlikely to change, and if it does I rather suspect online resources will change faster than the textbooks. The workbook on the other hand isn't possible to duplicate, but only as it's full of practice problems + answers that just isn't available anywhere else. Someday that might change, or perhaps I just haven't found it.

Continuing that theme is a blog from "Cool Cat Teacher" on comparing textbooks to buggy whips and railroads:  http://coolcatteacher.blogspot.com/2010/07/buggy-whips-railroads-and-paper.html .

Other sources for digital textbooks are http://about.ck12.org/ , an initiative to create "Flexbooks", which are freely available. When I last looked at Flexbooks the offerings were poor, but glancing at the chemistry text available it has improved substantially. Bookboon (http://bookboon.com/int) creates its own free textbooks, although they do put ads in them as well. WikiEducator has a link to these and a lot more ( http://wikieducator.org/Free_textbooks ).

Lastly, and completely unrelated, change.org has an article on the latest study from the U.S. Dept of Education : http://education.change.org/blog/view/why_peeing_in_a_cup_wont_win_the_drug_war. Apparently the last U.S. administration instituted funding for randomized drug testing in schools, and somebody decided to study it to see if it work. Science ruins everything.

Regards,
