If you want to use this popular communication format to help students learn but don’t want to give out your cell phone number, there’s an app for that. In fact, there are several apps for texting in an educational setting. One of the most frequently used is Remind. It’s easy to set up, free to use, works with either a web-interface or a smartphone app, and keeps cell numbers private for both sender and receiver. Other features include audio texting, attaching files, and translating text messages into various languages. Students can choose whether or not they wish to receive your text messages, so this could be a supplemental and optional form of communication to help those students who feel they could benefit from it. You could text students a last-minute change in classroom location, an upcoming due date reminder, or anything else related to your course content, protocols, or assessments.
If you’re more comfortable using e-mail or making announcements in class to communicate with students, that is perfectly fine. Software such as “Remind” may be helpful if you’re searching for an effective tool to communicate with your students on a platform with which they are familiar, comfortable, and competent.
