The Sounds of American English
Great site from the University of Iowa that provides a graphical presentation of each American English phoneme, from an animated Saggital Sam to video of what the mouth looks like when a voiced labiodental fricative is used, students will develop a very clear understanding of the pronunciation American English.
High interest topics in a slower, more understandable format for English language learners.
Boring name, but excellent stories with text, audio and sometimes even video support. Students can read, listen and watch the stories and then click on the 'activities' link to work on vocabulary, grammar and reading comprehension exercises.
A serialized video and audio presentation for learning English. Well produced with a great deal of vocabulary and natural language use in daily situations. The video is supported by grammar exercises and quizzes on the content and language structures presented.
