Embedding TubeChop videos in PowerPoint

I have previously blogged about TubeChop, which allows you to selectively crop YouTube videos, and it has been well received by staff and students. This means you can link to (or embed) just a portion of a YouTube video, rather than the whole clip.  It was only a matter of time before someone asked the question: "Can I embed the cropped video into a PowerPoint show as well as my Blackboard course?"  A quick Googling revealed the answer is yes, but it does involve a bit of work extracting the video location from the embed code TubeCrop offers you, not difficult if you follow the instructions available here...

Random Acts...

A colleague asked me for a random student generator, that's something to randomly pick students from a group, rather than generates random students to attend your classes.  This hopefully reassures students they have been selected to answer a question or do a task purely randomly.  A quick Google search found any number, and I went with this from Super Teacher Tools, , which picks from a list of names you have uploaded until they have been all exhausted.  I also came across a PowerPoint slide that randomly picked a rectangular shape, from a set of 10, which I have adapted to include as many rectangles as you want.  I thought this would be good because you could put your students' photos into the slide, to personalise it a bit more.  The downside of this one was the fact that each click gives you a totally random choice, so it re-picks from those already selected.  That's fate for you!  Contact me if you want the PowerPoint slide.
