Right now videos on Edpuzzle are not available without an internet connection. An internet connection is necessary so that teachers can see the progress of their students as they complete a video lesson. We track all the information on our servers so teachers can follow the activity of their students without any delay.
We also monitor internet speed of the user to adjust video quality and ensure that users have the smoothest experience possible with their connection.
We will explore the option of offline viewing in the future, but at the moment, be sure that students are connected to the internet when they complete their assignments :)
