Over the past two years I have recorded my lessons mostly using screencast technology as I do not like seeing myself in my videos. I also use my cell phone camera to capture the hands on projects. My students watch the lesson when they reach that point in the course. This reduces the down time for the accelerated students and allows them to move ahead in the course without hounding me with questions. This also allows me to help the students who need and deserve help. I do ask that the students collaborate with each other in moving forward which is an important skill. So did I create all the lessons that I use in class, absolutely not. I just provided the platform that the student can easily follow. For the most part I use this site and I my classroom site. Both built using Weebly, but many teachers are using Schoology for managing this approach.
If you're thinking it is going to be a lot of work on your end to get this going your are absolutely right, and I understand your concern of spending so much time changing your teaching style. I will testify that spending the time to create the videos for my class and creating my class websites has been one of the best things I have done as an educator. I have experienced so many benefits from this approach it is sickening that I wasted years educating my students the traditional way. My students are performing better than ever before when looking at testing data, they are more alert and responsible for their own education, my accelerated students are doing activities that I never had time to teach before, classroom disruptions are at an all-time low, and getting students caught up with missed work do to absences is no longer an issue. There are many more benefits not listed but you get the point.
The downfall of this approach is that you must have the technology resources to pull it off. I am fortunate enough to have a computer lab built into my technology lab. Most school districts have been upping their game when it comes to increasing the amount of technology in their districts. The cost of devices capable of supporting this approach has decreased significantly over the last few years. Lower end tablets and Chromebooks seem to be the most popular for doing this. If you don't have the resources ask for them, as many districts acknowledge that using technology in the classroom does work and are looking for teacher willing to use it.
