Using Edpuzzle to deliver instructional content

I have been using EDpuzzle for the past 2 years to deliver the instructional content to my students and I can honestly say it has elevated my flipped classroom to the next level.  Prior to EDpuzzle, I posted my video content on my website and or youtube but I had no way to check if students actually watched the video for hw.  I then added a google form for students to summarize the video but I still lacked the assessment piece for students to gauge their understanding of the content as well keep them engaged in the lesson.  EDpuzzle has done both and more.  Student engagement in the lessons have gone up (I have collected data via surveys before and after using EDpuzzle), they are coming to class with a better understanding of the lesson, and most importantly it provides me the ability to assess what part of the lesson students are struggling with so that I can focus on that concept the next day in class.  The website and their IOS app are extremely reliable and their support staff is top notch if you have any difficulties.   This has become the most important assessment tool I use in the battle to educate and engage even the most reluctant adolescent student.  If you flip your classroom or use video in any way in your instruction then you must check out this amazing site.
