(The rampant misrepresentation of researcher Edgar Dale's valid model of classifying learning styles is discussed in this entry in the blog of educational consultant Will Thalheimer.)

Contrary to popular opinion, research shows that lessons in which students interact with material, rather than passively absorb it, are not always better.

CMS/LMS provider Blackboard reported Monday that its plagiarism detection service, SafeAssign, has now been used to scan more than 1 million student papers. Blackboard debuted SafeAssign about nine months ago. SafeAssign is designed to eliminate plagiarism in student assignments.
