Video Recording Lectures or Modeling of techniques is a great tool for students to not only see what you are demonstrating, but it also gives students the opportunity to pause and/or rewind if they need to do so.
When video recording a lecture:
Rule #1 - shoot horizontally
Try to have a camera person
No camera person:
prop the phone/camera
don't worry about being seen starting/stopping the recording and walking away/to the device (it's ok)
Upload the video
to your Website folder in Google Drive (or a Public shared folder), then you can share the video with your students via Google Classroom or by link.
to YouTube and set the privacy to Unlisted and turn off Comments (Google Drive has been really slow to process videos, so YouTube is the best option)
If you have to prop your phone or camera up, be creative. You may have to add a book or something in front of the device to keep it from sliding like I did. At home, I sometimes grab a stuffed animal to "hold" my phone while I am recording.
Check the view and make sure the record button is accessible before you record (you may have to rotate your device to get the record button on the side you want it).
Setting your device on a stack of books to turn it into a doc camera works. You might need to prop it up a bit like I did with a pencil to get a better angle. If your phone camera allows you to turn on the flash during video like mine does, that is definitely a good perk to use.
Check the view before you start recording. Make sure you are able to view what is being recorded as you talk through the lesson. It's ok to slide the paper up and down or switch to another page as you go. Just be sure to go slow and leave at least 3 - 5 seconds for students to view a completed section before you move the paper or switch pages.
