I have developed The Helping the Handicapped Project for use in my tech class this past year. This lesson focuses heavily on students using the 5C's of technology: Communication, Collaboration, Creativity, Digital Citizenship, & Critical Thinking.
This is a perfect lesson to incorporate if your district is going 1:1, or already there. I geared this more towards iPads, which is what my students use, however, since this lesson relies so much on the 5C model, it could work easily with other devices/media with minor adaptation.
This activity also goes hand in hand with the Danielson model, and if you are a teacher that is being told to incorporate technology and need a unit that will be effective and take up a lot of time, then this is perfect for you. I did a similar project for my evaluation in 2012, and my administration were so impressed they brought over board members to view it.
With this purchase is included a pdf, with a working link in the upper right corner. It takes you to a webpage where everything you need is housed and done for you. All you need to do will be to supply students with the link. There are also copies of the project & assessment in both PDF / word form, which can be downloaded, or uploaded to Google Docs and changed from there.
