 really started in earnest after taking teaching in a blended learning environment course this past summer. So I started to implement the concept map activity, this term that's just wrapping up now. That was really the spark that led me to saying, okay, let's get this technology, use of technology enhanced in the course. Underlying that has always been my desire to have students become more self-directed in their learning and I saw that using technology could be a really nice blend of allowing students to go off in pairs or triads and creating a concept map, using the technology, peer to peer teaching is going on, they're becoming much more self-directed in their learning. So I thought the blend was really nice in using technology with my goal for students to take greater autonomy in their learning.
