Group activities are important in learning. This allows the learners to become more engaged in the learning atmosphere without realizing they are actually learning. During the test, they may become frozen on a question, but they remember one of the learning activities and the light bulb comes on and they remember the concept from the group activities. I enjoyed this course, it gave me new ideas in engaging my learners during diffucult lectures. I especially enjoyed the ball toss, in fact I plan on using this for a review scheduled today. Thanks
