Website Review: esl.about.com
In short: A large amount of pretty good teaching and studying strategies. Click on the tabs at the top to access materials for beginner students, intermediate/advanced students, and teachers. You’ll then see all the categories. Ken (the author) has written a huge amount over the years. The material isn’t incredible, but it is good—like a professional athlete that’s good enough to play for 15 years, but never becomes a star. The site suffers from too much distracting advertising.
For students: Sign up for one of the free English E-Mail Courses. Reminders to study in your inbox are very helpful.
For teachers: In addition to all the teaching strategies, make sure to check out the recommended books and classroom materials.
