Meta-Analysis on Critical Thinking

In this month's Review of Educational Research, there is a meta-analysis study by Huber and Kuncel entitled "Does College Teach Critical Thinking? A Meta-Analysis" (see attached). This and other related studies can be found at:   http://rer.aera.net

This meta-analysis of 77 educational studies concludes that college itself tends to improve critical thinking as measured by general critical thinking skills tests like the Watson-Glaser or California Critical Thinking Test or the Cornell, Level Z test.   However, they note that nursing has instituted as part of its accreditation requirements, training in critical thinking, and they chose to evaluate these studies separately, noting that systematic program-long efforts such as have been taken in nursing training has led to improvements in general critical thinking, but more importantly in discipline-specific critical thinking.  Why shouldn't we seek the same for veterinary medicine?
