Evernote

Students can keep notes and gather sources for their projects, all of which can be shared with their teachers and classmates.

Twitter

Twitter is an information network that’s available online and in app form. Conversations may seem trivial, but the valuable tool lets users share their thoughts, questions, links, photos, and videos. Students can tweet in journalism classes, posting reports online in real time, for instance, or on field trips, sharing what they’re discovering on their trips.

The Chemical Touch

The periodic table comes alive with an app that provides detailed info on the elements, standard amino acids, and nucleobases.

Shakespeare Pro

The complete works of the Bard, including 41 plays, are available with a few swipes and clicks of this iPad- and iPhone-enabled app.

Socrative

Want to know if your students have absorbed a lesson and are ready to move on? Available for any device with a browser (smartphones, tablets, iPod touch), this Web-based student-response system enables you to assess in real time -- via multiple-choice, short-answer, and true-false questions -- how much of the material your students understand. Students enter their answers on their own devices, allowing them the privacy to answer candidly, and results are tabulated immediately. Instant feedback!

SAT Prep Apps

1. The Official SAT Question of the Day, from the College Board
2. SAT Score Quest, the Princeton Review’s iPad app
3. SAT Connect for Apple
