I let students volunteer to draw a sketch of a cell organelle on the IWB, using two pens at once two students at a time and half the class had shared their knowledge (well a part of it) and we had found out that no-one could draw an IB standard sketch diagram of a chloroplast. All in the first five minutes.
Handy things about using an IWB:
- Students were keen to use the pen
- I could easily resize and move diagrams that were too big
- we have saved the work for a little reminder in a week.
- we could duplicate the page and annotate the diagrams with functions of the organelles.
