I chose two different introduction to statistics classes and asked the students to
participate in this study. I taught one of the classrooms traditionally, giving lectures with
examples and assigning homework out of a book. I flipped the other classroom in the
following way. Students completed work on an online intelligent tutoring system called
ALEKS where they could see explanations of concepts, see examples of those concepts
in action, and interact with those examples until they could successfully complete similar
examples on their own. During class, I gave students activities to complete (mainly in
groups of 2). These activities were sometimes open ended investigations, and other times
the activities clearly stepped students through the investigation and asked them to explain
what happened.
