I read the article, What Has Podcasting Done for You? Great Things Often Begin in Small Ways by Jim Moulton. I love the idea of the students using podcasts to record morning announcements, etc. I think its great for students to get involved in these type of activities, so they feel that they are contributing at school and also get to learn some new technology. I also agree that the students may be more likely to pay attention during announcements if they are unsure who is speaking and/or if it is a friend/classmate. The High School started posting a video once a week of students reporting the news. It has been a big hit amongst the student population.
