A great resource for electronic portfolio templates, etc. Dr. Helen Barrett's Electronic Portfolios
Site also contains a link to Cambridge's Deep Learning presentation that sounds really good.
She made several presentation at the TLMI conference at Otterbein college this week. Terrific conference, as always!!
One presentation was talking a good bit about what I like to call "the dark side of portfolios." Discusses the pressures on portfolios for student learning as well as portfolios for demonstration of mastery of concepts. Assessment for learning vs. assessment of learning. Story of learning, not a checklist of skills learned.
