I used to listen to podcast of music each week, I liked it so much and it was made by an individual who was a big fan of music, and I also listened to the ESLpod ,these days, which has different topics every a couple of days. It offers a variety of topics, like business, social, cultural... and it speaks in a lower speed in cater to the language proficiency to ESL learners, to learn the language in a context of learning cultural. This podcast is really interesting for ESL learners, especially for those beginners or intermediate level students who are in a EFL environment, where they could not have much exposure to the English.
Meanwhile, I found another one which is really interesting, which helps me to learn French,One Thing In A French Day , it is made and produced by an individual each week, she talked about the tourist attractions, cultural issues of France, and with a natural speed of speaking, the best thing is it has the text on the website, which could be taken as the reading or dictation materials. If I teach English or French, I would like my students to listen to these more natural podcast which relate to cultural issue, and make them interested in learning this languages. I can also expand the topic. For example, one podcast of it is about the vacation plans,Les prochaines vacances, I could let students to dictate it, and talk about their own vacation plans as an oral practice or let them write with some target vocabulary as a writing exercises.
