You left out one important constituent: the learner. Ultimately we are
responsible for making learning visible to the learner. Claudia and I
touched on this topic in the attached paper.

Just to place all my cards on the table, as much as I hate to suggest
we head down this route, I think we really need to instrument
activities themselves (and build analyses of activity output) if we
want to provide meaningful statistics about learning. We've done some
of this with Turtle Blocks, even capturing the mistakes the learner
makes along the way. We are lacking in decent visualizations of these
data, however.

Meanwhile, I remain convinced that the portfolio is our best tool.
