The document discusses using social media and other online tools in university classes. It proposes three benefits: 1. Social media allows for interactive engagement between students and professors, making it easier to get feedback and answer questions in real-time. 2. It provides a convenient way for professors to send homework and for shy or less confident students to participate who may find face-to-face settings difficult. 3. Social media can be a place for discussion and sharing of different opinions between students and professors, helping students understand other perspectives.
