PowerPoint, while sometimes vilified can be used to address multiple types of learning. In the presentation, you can have pictures, text, videos, and sound. You can print out slides for students to follow along with the lecture and you can post it online or print it out for absent students. This is a great resource for using PowerPoint in the Classroom -http://www.actden.com/pp/
Class web sites and blogs are also a great way to support student learning through differentiation. A class site or blog can have resources and help links, reminders for upcoming due dates, discussion forums and more. Students can also create a web site or blog as a assignment instead of a typical quiz, test, or paper. Creating a class web site or blog is very easy. Here’s a good place to start if you want to create a web site or blog: http://goo.gl/m0bO
Virtual Field Trips are another good way to have students experience and learn in a way beyond the typical lecture. These can be used by the teacher with the whole class or by individual students. Here’s some tips on where to find some great virtual field trips. http://goo.gl/3mVF
Many students are not the best at taking notes, or being organized. Google Calendar, Google Tasks (through Gmail) can both be used to keep students organized. There are also a lot of other great student resources online for students to use for studying and for staying organized(http://www.techlearning.com/blogs/33782). By sharing these with your students, you offer them different ways of staying organized and being successful.
Evernote is free note-taking, web clipping, and organizing online tool. Students can use it to take notes, clip information from the web, upload files and connect to notes, and can even share notes with others (and the teacher can share notes with their students). Students can access their notes from any computer or smartphone. http://www.evernote.com
