Here's another teacher's podcasting project with her students. The students do prepared readings from books called the Literary Salon. There is a link to student samples included in the project.
She also includes several other posts about using blogs with her 4th grade students. She includes things to consider and why to use blogs with kids. She also discusses her class' blog project about Sierra Leone. She also posted about several other teachers, both elementary and secondary, who are also doing bloggng with students.
I know I will be returning here often to see how it's going. I do hope you can see these examples from your vantage point!
