The AAC&U/Global Perspectives Institute report commissioned by the Department of Education on "A Crucible Moment: College Learning and Democracy's Future" (October, 2011) focuses attention on education for citizenship, and suggests that answers should be sought under four headings: knowledge, skills, values, and collective action experiences. William H. Newell, "Contributions of interdisciplinary studies to civic learning: An addendum to A Crucible Moment," Issues in Interdisciplinary Studies 31 (2013), 192-200, outlines how interdisciplinarity can serve the various goals outlined in that report.
The more general Lumina Foundation's Degree Qualifications Profile at http://degreeprofile.org/ (which also was co-authored by AAC&U) has five components: it breaks knowledge into two components – general/integrative and specific – lists skills and civic learning as well, but also speaks of applied learning.
