I think this is fairly new (started about a year ago) and it has a number of pages, for example a list of the ACRL Information Literacy standards with teaching tips; links to resources related to assessment. As you might guess, it it is focused on information literacy in scientific disciplines. The Science Information Literacy wiki is at http://wikis.ala.org/acrl/
Additionally, there is an active group on Facebook http://www.facebook.com/pages/Science-Information-Literacy-Wiki/61526697085 which has "first wednesday" discussions.
