Website Review: toeflcafe.blogspot.com
In short: This blog isn’t active, but it has great stuff that will help you on the TOEFL. You’ll find videos on all the different sections of the TOEFL, articles on how to prepare for the test, and thoughts from students.
For students: The speaking practice application is great. You can practice taking the speaking test. Use software on your computer to record yourself.
Also check out http://toeflnow.com. They have products that will help students prepare, some free practice tests, and prep videos.
For teachers: Ask your students to each watch a different video and present it to the class. They’ll learn their section very well and the presentations will help with their speaking skills.
