This document summarizes Blackboard's i-SMS interactive messaging system. It allows instructors to engage students during lessons by posting poll questions or discussion prompts that students can respond to using their mobile devices. The current system allows anonymous student feedback via SMS. Future plans include making it mobile-enabled, allowing instructors to pre-create questions, and integrating with other student response tools like eClicker and Socrative for more interactive lessons. Technical specialists are working to expand the system's capabilities.
