This website has some great video lessons, complete with lesson objectives, notes for the instructor, and links to external resources. It doesn't have anything for English, but it does have a big math and science section.
A free, downloadable website that provides students options for accessing web content minus the clutter. It is a great tool for students that need to change the visuals on a page, bringing the text forward. You can customize the font size and type to suit a student's style. Let's you save articles in that format to your iPad too.
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).
After reading chapter two of Blogs, Wikis, and Podcasts I was slightly hesitant about starting a blog for the school. The author mentioned this website as a good resource for parent letters and student guidelines. This is the homepage wiki for Bud's resources, but there are many good links shared on it. Good luck!
iPads are in more and more classrooms... This link includes a link to great math apps as well as some good discussion from math teachers using Khan Academy and others.
This website is a great resource to the visual learner and the free version allows you to create a visual concept map posting website links and videos. You can also make your visual map public and have multiple people working on the same map.
