Lasers+Aliens=Awesome Fraction Game

I am totally addicted to this game right now thanks to Dan Meyer. Who cares that it’s probably designed for 4th graders!  I like how the creators of the game explicitly state that the game is not a lesson in fractions, but rather requires knowledge of fractions.  I think this game would make a great starting inquiry into fraction concepts.  Students can play the game and later reflect and induce some fraction rules.  That and it’s just fun!

Assessment: Who’s in Control?

What if students were able to choose when and what they wanted to be assessed on?  That simple question was posed by colleague, recently to me in a staffroom chat.  It quickly exploded into an hour long discussion, that resulted in about 2 weeks worth of work on re-imagining my classroom experience for next year.

I think I was alway comfortable with the idea of students choosing their own topics or concepts for inquiry, but I was never able to come up with many good assessments that allowed for good student initiated action.  It was hard to think of open ended assignments.  My colleague’s question allowed for an end-around to the problem of the teacher structuring tasks, and then making students fit their learning and inquiry into the teacher’s structure and time-frame.

Luckily, I teach within an MYP context, so there are skill driven objectives set out for…

Avoid Plagiarism: Google Goggles To The Rescue!

Have you ever needed to find the source of an original image, but you can’t remember where you found it?  Try using your iPhone to take a picture of the image on your computer using Google Goggles, to locate where the source site is located.

In my latest foray of total nerdiness, I decided to create an HTML5 widget to add to my class page and iBook that I’m building for my unit on plants.  Since I decided to go full out on this one, I wanted to be able to share the resource.  So I scoured the internet for Creative Commons licensed images (which led to a few blog posts of their own: MorgueFile, Behold, ImageAfter).  However, when I finished, and decided to license my own work, I realized I had forgotten to attribute two of my pictures.  Unfortunately, they were public domain off of the Wikimedia Commons, and I couldn’t find the originals to properly attribute them.  Since I haven’t yet built that time machine to go back and kick myself for not recording my sources better the first time, I ended up pulling my iPhone out of my pocket and using Google Goggles.  Found the first image with ease, but struggled with the second.  Luckily finding the first one jogged my memory and I was able to browse until I found the second.

I know there are searches like TinEye out there, but it didn’t work for either.  I honestly had to laugh at myself taking a picture of a picture on my computer, to search for the picture on my phone rather than on the computer.  Bit round about, but effective.  Whatever gets the job done, right?

Infographics in Abundance

I’m always a little bit wary of info graphics, largely because as a scientist/mathematician I want to see the raw data too, just to make sure sure I agree with the presentation of the data.  However, that doesn’t mean that all info graphics are incorrect and they are increasingly more popular, so teaching students to evaluate them is an important 21st century skill.

The Aside Blog has a fantastic page full of links to various info graphics for you to use in class.  I also love the video they highlight by Column Five which talks about specific visualization strategies for presenting data.  So if you’re interested in data visualization and info graphics, head on over to the blog and start indulging your inner data geek.

iPhone Microscope: just add water!

I don’t usually post hardware solutions to classroom technology issues here at Embed_Ed, but this one was too good to pass up!

Alex Wilde has posted at Scientific American about a simple trick to turn your iPhone camera into a microscope!  One drop of water is all you need.

I tried this out quickly, and found that indeed it did work.  Flipping the camera over quickly and smoothly seemed better than trying to slowly turn the camera in regards to getting the water droplet to stay in place.

It’s tough to hold it and shoot as well, which is why Alex suggested using something as a stand.  Moving the object would probably be easier than moving the camera!

If you’re interested in other DIY iPhone microscope tricks, check out Sallaha’s Blog.  She has some great examples of using various common lenses.

Multiplication Waterfall

Ok, so this isn’t something that I’ve figured out how to embed yet, but it’s still great math tech, with an art twist!

The Multiplication Waterfall by Stefanie Posavec and Hadrien Jouet is a nice little web app that turns multiplication into art, by replacing the numbers with symbols of various colors.  I think this would be a fun way to create a pattern investigation worksheet of some kind, or a way to encourage students to begin a math/art inquiry!

ImageAfter: Free images and textures

ImageAfter is a good source of free to use images and textures.  While the site experience is not quite as nice as the MorgueFile.com (see my previous post), it is a pretty good go to if you’re still searching.
