As previously mentioned, I've been working with a non-profit that runs after school tutoring programs helping with the math side. Part of the problem is that the program leans toward the humanities side and some of the tutors are not at all comfortable with math.
I've been throwing together some short, smart-phone friendly videos for this target audience.
Everything here is modular. I dictated the scripts to dragon, created SVG graphics in Inkscape, put together the slide in Impress and PowerPoint, recorded the audio in Audacity and did the final edit in KDENlive. It's quick, not slick, but it is set up in a way that any given element can easily be changed.
Any feedback is appreciated.
