Are you thinking of flipping your classroom or using blended learning? Here is a great tool to help you add some videos with built in assessment to your lessons.
EDpuzzle is a free website that will let you take either videos you make yourself or videos you find on the internet and edit them to just the parts you want and add some assessment questions to make sure the students are watching and understanding them.
Here is a link to a great review of the website. http://www.edudemic.com/edpuzzle-review-easy-use-tool-lets-teachers-quickly-turn-online-video-lessons/
