Hi Patricia, Good for you for using many different modes of delivery of content. By using this method you are not only keeping the course interesting you are appealing to the different learning styles of your students. There are 7 major intelligences as identified by Howard Gardner and all of us process information within three of these intelligences comfortably. By delivering content in different ways the learning style of the student is hit and the intelligence that is used for processing is hit as well. This is a double support combination that really facilitates learning. Your point about looking for new and better ways of offering instruction is a good one. We need to keep our eyes open to different applications that we can use in instruction and these may occur in settings in our everyday lives. Point is by keeping an open mind we can find ways of doing our job better and we really wasn't looking for this strategy it just became available. Gary
