By providing my students the solutions to some exercises through Screencast-O-Matic videos, I was able to cover more in less time. Students can repeat my explanatory videos as many times as they want and can watch the exact strategy and rules I use to formulate the correct answers. It also saves time during class by avoiding multiple repetitions of the same grammar point.
Here you can find one of those examples: http://screencast-o-matic.com/watch/cIXohlVPaQ
