Twitter can promotes social connections among students. It can be used to enhance communication building and critical thinking. Twitter can be utilized in a graduate seminar requiring students to post weekly tweets to extend classroom discussions. Students reportedly used Twitter to connect with content and other students. Additionally, students found it "to be useful professionally and personally". Twitter was used to discuss material, organize study groups, post class announcements, and connect with classmates. Twitter allowed students to participate with each other in class (back channel), and extend discussion outside of class. Students used Twitter to get up-to-date news and connect with professionals in their field. Students reported that microblogging encouraged students to "participate at a higher level". Because the posts cannot exceed 140 characters, students were required to express ideas, reflect, and focus on important concepts in a concise manner. Some students found this very beneficial.
