Continuing with using PowerPoint or Keynote in a different way, I was working with a teacher in a school that has intermittent internet access, 2 computers that work sometimes, and she has a projector that she uses in a limited way.
I suggested using the Projector and her laptop as a learning centre activity area. I showed her that she could adapt some of her printed activities for visual interactive learning by creating them in PowerPoint or Keynote as the example below shows.
Students can go to the centre and use Whiteboard markers to write the letters, a buddy can check to see if they are right, another child can move the slides with the arrow key on the keyboard. And the teacher can keep an eye on what the students are doing because it is on the Whiteboard through the projector. You are now making use of technology with students in control!
