Calling all actors? Thing 15: Screencasting

Although I'm not new to screencasting, I honestly haven't used it beyond the training I received on it during a technology training class. However, I certainly have been looking for something like this for essay grading. I have a vision that instead of handing back a marked up essay with written comments, that I can return to students a visual and audio of my thought process while I mark up their essay. Since feedback is critical to improvement in writing, I want to give as much feedback as possible. And let me be honest, the further I get down in the pile of essays, the less inclined I am to write tons of comments. That's why it takes me so long to grade papers. With a visual though, I can write minimally but talk through and show what I'm talking about in the paper. I've not been able to find such a beast to help me accomplish both things at once though. Screen-O-Matic gets me there somewhat, but the shortcoming is that there is no way to filter through the entire essay. It appears that I can only chunk it, which will lead to multiple files for students. Not good. However, I have to say that it's at least a start. Here's what I practiced today using Screen-O-Matic. Forewarning: it's choppy and awful! But, it was worth the practice.

Initial thoughts: excellent concept! I want to be able to use this for my essay grading. I see that files can be exported as MP4s. I just need the capability to go through an entire essay in one file.
