Rabbi Karen G. Reiss Medwed of Hebrew College wrote a guest blog post about a substitute class that she taught at Prozdor High School. The ninth grade students learned about Mitzvot with the help of phone texting. They answered questions via their cell phones and communicated with their 'lifelines' to discuss points raised during the lesson, involving parents, friends and other contacts in the animated discussion of Mitzvot. The students loved this lesson. They loved using their phones, but more than that, they loved the learning.
