Comment Imagine Learning English (Score 1) 145
I teach ESL at a K-5 elementary school. My school just started using Imagine Learning English - www.imaginelearning.com - which is really impressive and useful, though expensive. The program has
many activities which show videos of mouths making different sounds. Be aware though that the program does not allow you to designate the activities a student works on - it gives an hourlong assessment on first use, and then works on areas where the student is deficient. If you login as a teacher, you can do any activity, BUT it doesn't track your progress then...
Still, the program is awesome and anyone interested in Computer Assisted Language Learning should check it out.
