Remind is a great tool to enhance and reinforce communication systems you have already got in place. In addition to your existing Edmodo account, class blog, OneNote Class Notebook, or hard copy assignment sheet, you can send a one-way text message to remind students about important due dates, current events, upcoming tests and quizzes, schedule changes, field trips, or other pertinent information. In matter of fact, Remind suggests open house or conferences as a great time to introduce the service and share sign-up instructions with families.
Remind can also be used to extend positive messages, perhaps before exams or tests, or even before a day with a substitute teacher.
However, please note that, for safety reasons, the service does not allow for individual students to be contacted.
