Nagasaki, iMovie, and others

Hi,

More stuff. You'll notice that I often link to www.freetech4teachers.com - I read a fair number of blogs, but that particular one gives a number of practical useful tools. I recommend following it.

First off, the Nagasaki Archive, which uses the Google Earth plugin to preserve the history and stories of the survivors of August 9th, 1945. Only a few of the stories are in English (even in the English preview), but I found that using Google Translate I could copy and paste the text and get a passable translation into English anyway.

Next is an iMovie quickstart guide for those with a Mac...or merely students with one!

The next is a beta site called "Text the Mob". It's a polling service that would allow posing a question and allowing students to use their cell phones to text in their answer, essentially acting like the 'clicker' systems. There is a free version (with ads and limited in the questions). I don't exactly see students being allowed to pull out their cell phones in the near future, and I think a clicker system would end up being simpler and more useful (especially if embedded within the Smart board lecture itself). Cell phones are quickly becoming the mobile computer of choice, and I see this more of a harbinger of even more tools to come. You can get a TI-83 emulator for the iPhone (although the reviews aren't great), soon I expect you'll be able to add...everything.

Have students who do a double take, or feel like teaching is the blind leading the blind? The "Idiom Dictionary" may be just the ticket. In SciTech I will use contemporary examples of issues and reactions. More than once an ESL student has questioned the meaning of a common idiom - the Idiom Dictionary means they can at least check for the meaning while working on their homework during prep.

The next one is from "Bad Astronomy", an excellent science blog. This particular article summarized the 'State of the Climate' report, with some key diagrams to make it obvious why and how we know that the Earth is warming. It's directly applicable to Science 10, but in general I find it useful to have such resources on hand, whether it's global warming, 911 conspiracy, moon landing, vaccines, creationism,etc - it's often an opportunity to talk about the nature of logic, evidence, and critical evaluation of sources.

This is just an 'oohhh, cool...' series of pictures taken using computational re-photography. Using a program to adjust a camera position to take a picture exactly where a historical picture was taken, some amazing amalgams of historical and modern scenes. I assumed it would be of interest to history teachers, but I thought they just looked amazingly cool. There is some indication that the future idea is that this program would be released as an iPhone app, allowing anyone to create such photos.

Lastly, science in progress. It's a dinosaur dig in progress (you can use google translate to have it appear in English).

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.
