Imagine a scenario for parents, they've just picked up their child in a centre or kindergarten,
'How's your day been?'
'Who did you played with?'
'.... I had banana and yoyo .....'
An e-portfolio is a great tool to partner with parents for their child(ren)'s learning, educator can record videos. It's nice to keep children's drawings for parents to take home, but the most important part is what the children were saying while drawing the picture.
A nice presentation on e-portfolio found in Prezi: An introduction to e-portfolio
