4、Podcasting is like radio broadcasting, except that it uses the Internet. Anyone with a computer and a microphone can record a show about any subject. Anyone with a computer and an MP3 player can download the podcasts(網(wǎng)播節(jié)目) and listen.

Podcasting does require some technical knowledge, but not very much.

Many education-related podcasts are aimed at college students. But a growing number is created for, and by, students in middle school and high school.

At mountain View Alternative High School in Centreville, Virginia, the students have spent several weeks preparing for their project. They have written their stories. And they have recorded music and other sound to use in their podcasts. Next, they bring together the different elements on a computer.

Their teachers help by offering comments and suggestions. The students have made decisions about how to present their information. They have decided how it will be read, and how other sound will be used.

Some students decide to read their story themselves. Others choose to create a different effect by having someone else read parts of it.

Through voices, music and sound effects, the students are able to create something deeply personal.

With podcasting, students are using their skills in writing, reading and public speaking. At the same time, they are learning several new skills. They learn to work with the computer programs that are used for podcasting. They also gain experience in communications, broadcasting and problem-solving.

Podcasts are being used in English classes and social studies, as well as foreign language classes. Being able to listen to recordings of their own voices helps students to hear mistakes.

There are tens of thousands of podcasts on the Internet. They can be found on almost any subject, from current events of financial planning and poetry. People are now recording their thoughts on just about everything.
