One of the biggest concerns I hear from faculty regarding using social media in their classes is whether it actually helps learning. This is a great point and worth talking about! I think that's why it's important to always go back to the CLOs (Course Learning Outcomes) and examine whether the functionality of social media helps students achieve those.
As a faculty member who teaches public relations, I think it is particularly useful to use social media. After all, my students will be using social media throughout their careers. However, social media can be used across a variety of disciplines to increase student learning. For example, if faculty have a "knowledge" based CLO, they might consider having students identify articles, videos of infographics that relate to the topic. You'd be surprised how many resources there are for chemistry or the history of British literature or any other topic out there!
Students can do much more than simply find and share a resource on social media, though. They can become a resource creator. Faculty can empower students to analyze data and develop their own pieces of content that can then be shared in the social world.
Social media is a tool, one among many, that faculty have available. When I've integrated these strategies into my teaching, I've noticed students have more fun. While that is not my goal, necessarily, I do believe that my students learn better when they are enjoying the process. In addition, I hope that my student recognize that they can begin contributing to their future industries and career fields now by engaging conversations, sharing resources and developing materials that others can use.
