I liked the Reading Zone Blog because it is comprised of a young English teacher's lesson ideas, book reviews, and other classroom tips. It is well organized and easy to read. I found many of her blogs useful to my own teaching.
This website is an amazing resource for students and teachers. The Study Island website has aligned with state standards and created tests, activities, and games that promote student mastery of each standard. Students are able to use their Study Island account at school or at home and teachers can monitor their progress with the reports that are provided from the program. I think this site is an excellent resource for teachers to utilize in order to ensure that students are mastering the necessary standards. It can be very useful for differentiating instruction and using with small groups, or as a computer center station in the classroom.
The Daily Riff is a great site for articles about education, technology, and a variety of other interesting topics. It sort of reminds me of Huffington Post, but more niche.
This link to the Oxford English Dictionary is an invaluable resource for Middle School ELA and Secondary Ed English teachers. I can see it as a frequent "go-to" site for Student Researchers, providing more interesting content than a standard online dictionary. Because the OED is concerned with word origins, I believe it would be helpful in creating bridges with ELL students as well, giving them a chance to see the linguistic contributions their language has made to ours. Check out the link in the lower center column for teachers and students (resources and lesson plans).
