'Voki to teach my class - how extraordinary'

Last week in year one, this was exactly the thought expressed by my mentor teacher (MT).
We've began learning about mapping and more specifically oral and written directions. As an activity for our numeracy rotations, I organised a couple of voki to give instructions. ie

We walked around the forest before stopping at the bridge
The lake was not deep so we walk through it
At the mountain we turned left

To place in context, learners were given a map of an island, which included a variety of locations, the lake, the cave, the volcano, the bridge, the forest etc. In groups of four or five, (rotation groups) they took turns to use the IWB and click on the voki's to get the next instruction, and then replicated the instruction on their maps.

Achievement was determined from their final placement on the map. If they mistook a step, they were offered the chance to go back and retrace. (the advantage of individual learning and technology)

The voki were interactive in that each child had the chance atleast once to click on the next voki and lead their group in determining where the voki said to go. This created a real enthusiasm to progress, as everyone wanted not only one go but as many as possible. :)

Another idea I've floated is for story time, but I'm still determining if voki are the best ICT, am thinking a PowerPoint were you pick the direction of the story using the action buttons. Allowing learners to take ownership and really create their own story within a formulated use of the platform.

I've considered using voki within other contexts such as conversation starters, see George W Bush, but find the limited speech an issue, although I recognise it can be overcome through alternate solutions. Would be interesting to see a modern history unit of work which Incorporated narratives drawn from some of the key actors, or just a voki which directed students between activities to formulate assessment.

Any thoughts?
