My colleague and I are in the midst of writing up an outcome evaluation that
we did comparing my TBL and his lecture version of an intro criminology
course.  We're still analyzing the data, but the initial results suggest no
differences in grades on two tests measuring three different learning
outcomes.  However, TBL students self-reported improvements in soft skills.
 I hope to have a draft done by August so if you email me then
([log in to unmask]), I'd be happy to send you a copy of the paper.
