I have just had a new article published. It explains how to use free software (one part of Office Mix - an add in for PowerPoint) to make screen recordings. This is another easy way to create screen recordings that can be used for flipped and other styles of blended learning courses.
Many teachers are already comfortable with Microsoft PowerPoint and thus they can move to making screen recordings simply and with relatively little discomfort. There is no daunting new piece of software to learn.
Part of the article is available on this site (I am not allowed to publish the article elsewhere for 60 days after publication), and the full article is available at eschoolnews.com.
