I use CamScanner, an app on my phone, almost everyday. CamScanner will scan a document in as a pdf and from there you can share it to various media. I simply hold my phone over a document, student work, my notes, a key that needs to be posted; then take the picture, and the app does the rest. Super easy, and faster than the old scanner I have here at home!
My other favorite tool is a Google Labs app called Canned Response. Our district uses Gmail. All of our students have Gmail accounts. When I am grading papers and a student (or more) doesn't do well, I want to alert them right away because we have a district-wide retake policy. Canned Response allows me to create a response and save it. Then when I want to use it, I simply open "compose" and choose the "canned response" I need ... fill in the student's name ... and send. It saves me from having to copy and paste a typical email.
Here is a sample canned response:
I graded your paper on ... today.
Your grade was below 70. If you would like to repair this grade, please come to tutoring one morning in the next 5 school days.
I fill in the blank with the assignment that I graded, fill in students' names in "blind copy" and email.
These 2 techie tools are my favorites this week!
