Using Social Media Sites to teach students to become more proactive within their community doesn't mean you have to create a specific unit or lesson, but more to integrate Social Media Sites into your existing lessons. A teacher can use SNS as a warm up activity, use SNS as a primary resource to enhance writing assignments, use SNS to generate class discussions, or even use SNS to foster and enhance key terms found in their textbooks. By using SNS as part of your normal lesson plans, students will be more exposed to news and current events compared to traditional assignments of telling students to watch or read the news. Using technology that students likes to use, plus, students reading about news and current events from their favorite SNS or celebrity can cause students to become more aware what is happening around them and their communities.
I like to use SNS sites such as Twitter, Instagram, or Facebook to start off my class as a warm up activity and hold class discussions based on what topic we are learning that week in class. For example, I would ask students to look up on their SNS on topics or celebrities who are discussing about "Black Lives Matter" in relation to Constitutional and Civil Rights topics we are learning in their textbooks.
