Most students have access to email through their phone, so be sure to reach out to them through email. Phone calls are also an option. There is a mobile phone app for Blackboard Learn. Information for students about using the app is on the KeepOnLearning site. The app is most useful for email, accessing content, videoconferencing, and discussion threads. Complicated written assignments are difficult for students to submit by typing on a phone. There are creative solutions such as written assignments that can be photographed and attached to the assignment tool.
