A Brave New World-Wide-Web
Last February I did a presentation to student teachers from SFU. It was done on Powerpoint and I wanted to put it on a wiki so I added it to a service called Slideshare. By adding it there, others could see it as well as the SFU group. I was shocked at the response, here are the current stats:

A number of people suggested that I make it into a video. I decided that I would do this for the end of one of my presentations at BLC08 this summer. So I added to the Powerpoint some details about how I am a networked teacher, as well as some music, and here is what I came up with in video format:
(It loads faster on the web site here. Or click below and be patient while it loads.)
One thing to understand is that this was not an easy process for me! I had a really hard time converting my Powerpoint presentation with timed advances into the video you see above. In fact, I didn’t have it ready until I had some help from my network this weekend. (I had to show it in Powerpoint format in Boston). You can see this video in very poor quality, here on YouTube, but it is crystal clear above thanks to another free service that was pointed out to me, called Blip.tv. I’m by no means an expert, but more than ever I’ve become connected to people who can help me! 🙂
The student quotes in the video are real quotes from feedback that I got on my first blogging and wiki experiences with students. These experiences really changed my thinking as a teacher.
So there is a story about me and some of the things I’ve done online. I hope to feature some of you with your experiences. It can be as simple as describing a link you really like, or a lesson you’d like to share. Or it can be a story about how you’ve used technology to really engage a student or a class! Let me know what your thinking and I’m glad to help you out with it!

Did you miss an edition of Digital Magic? Is there one you want to look back on again? Here are all the editions of Digital Magic in reverse order, (most recent first).
Have a great week!
A round table has four deep pockets equally spaced around its perimeter. There is a cup in each pocket oriented either up or down, but you cannot see which. The goal of the game is to get all the cups ‘up’ or all the cups ‘down’. You do this by reaching into any two pockets, feeling the orientation of the glasses, and then doing something with them, (you can flip one, two, or none). However, as soon as you take your hands out of the pockets the table spins in such a way that you can’t keep track of where the pockets you have visited are. If the four glasses ever get oriented all up or all down a bell rings to signal you are done. Can you guarantee that you will get the bell to ring in a (maximum) finite number of moves, and if so, how many?

You have two glass orbs of equal strength and a 40 story building.
Your task is to determine the highest floor from which you can drop an orb without it breaking.
What is the least number of drops required to do this?
Both orbs may be broken in order to determine your answer.
