Good article but see if you can spot the error in CUPS.
How could you apply principles/concepts from this article at a MS level to el ed or HS? Think about Common Core State Standards and the student learning objectives that emanate from them.
take notes, collect web clippings, upload files, share notes with classmates, get organized.
The site allows students to track their classes and assignments, and even will send reminders (email or SMS) for upcoming assignment due dates and test dates.
Students can work on homework together and help each other out.
I like this website b/c it's collaborative and addresses "real world" issues and/or problems. Many activities require data collection which is conducive to setting up, collecting and reporting using spreadsheets.
