In the Organizational Leadership and Learning Program at UofL, we use the term blended in a couple of ways.
First all of our 8-week classes, whether seated or online are blended in that that ALL of the material is online. Students are responsible for all content whether the instructor covers it in class.
We also consider blended in how we develop content. Since students are from all over the world, all of our lectures are usually either PowerPoint voiceovers and lecture videos.
In my instructional strategies, I start my training with myself on camera explaining what the lesson covers and then there is a Camtasia video explaining the topic. The students then have an activity to perform based on the content. This activity is shared a number of different ways for feedback; Voicethread, discussion boards and learning journals.
