Why didn't anyone tell me that Screen Toaster (the web service) died? In case you never noticed (like me), Screen Toaster was an online screencast creation software that also hosted the screen cast videos. I had used it to make a screen cast tutorial for numerical calculations in a spread sheet.
Good thing I checked to see if it worked before my lab next week on numerical calculations. That would have been embarrassing.
So, in a sense this is a repost. If you want to read more about numerical calculations - check this out. And here is the screen cast. it goes quick because I know students have a short attention span (plus they can watch it more than once).
