Sorry I haven’t posted in a couple of weeks. I’ve been a bit busy and haven’t really stumbled across anything new and cool in educational technology.
For the next week or so I’ll be teaching sound in my freshman physical science course. I use an oscilloscope program on my computer to do this. I’ve seen several different programs for doing this and most of them cost a lot of money. The one I use is free and from the descriptions I’ve read of the costly ones it is better.
I use Visual Analyzer. The download site is in Italian but all you need to do is click on Download VA near the upper left. For those interested I’ve also created some simple instructions on how to Use VA. Over the course of this week I’ll post how I’m using VA to teach sound.
