Making your video recording
In making video recordings, it is natural initially to be conscious of the camera and consequently video recordings and it will be difficult to capture authentic evidence of your teaching. The best way to ensure that you obtain authentic evidence of your teaching is to make several recordings, until you and your students forget the camera is there.
For whole-class activities, set the camera up on a tripod giving a wide angle view of the classroom or the groups involved. It is often best to film from the side. It is vital that speech is clearly audible and while modern cameras have good audio reception, you may need to use a separate microphone to ensure that student talk is clear. If you are filming small student groups and circulating among groups it may be best to carry a handheld microphone to record your voice and the voices of the students.
