Podcasting is literally making a short movie, and adding a sound clip to it. It is a great tool for teachers to use in the classroom because it can provide a new means of instruction both when the teacher makes the podcast and also when the student makes their own. Teachers can use them for any subject in order to teach students, and it is a great way to engage students in the classroom. It is definitely different from an 'normal' and 'average' lesson.
PROS: Teachers can make an engaging lesson for the students using technology. Students can make their own podcast and actually learn while doing the hands on activity. Podcasts can be used for any subject, so they are versitile and not just focused on one subject.
CONS: They do take some time to make, and teachers do not always have the time to create one. Sometimes students do not have the knowledge of podcasts in order to use them or create them properly.
Here's a wesite that shows students making a podcst together, discussing frog dissections. You can see they are learning lots of information about dissections and frogs in general from making their own podcast. They get to DO rather then just WATCH.
