Challenging students with important ideas: social media and information gerrymandering

We want our young citizens to graduate from school scientifically literate and ready to tackle tomorrow’s problems; to be equipped to create a better future for themselves and for others.

We’re continuing to centre our lessons around important real-world issues that both challenge students and develop their critical-thinking skills. In a previous blog post we explained why we create science news lessons.

In our latest science news lesson, we’re tackling how social media can influence how we think, act and even vote.

The influence of social media

Your students may be asking you about a popular documentary on Netflix, The Social Dilemma. The documentary interviews the inventors and early employees of some of the apps we (and, more importantly, our students) use daily and talks to how manipulative their technology really is. It is required viewing for teens and adults alike.

We’ve created our most recent lesson so you and your students can discuss the role of social media in their lives, what they see in their social networks and how this can skew their perception of the world. As we detail in the lesson, recent studies demonstrate that social media can influence our mood, personal beliefs and whether we vote.

This lesson looks at a number of issues including social media and its algorithms, ethics and intolerance. Students practise a range of skills including collating, graphing and analysing data, and analysing and drawing conclusions from a piece of artwork. The lesson can be used in a variety of different ways: as a break after a test or after the exam period, at the start or end of term or as a special interest piece to break up your current teaching.

Filter bubbles and information gerrymandering

Filter bubbles

In this political climate, it’s difficult not to infer how these ideas have grand implications for the way people make decisions. A recent article published in Nature, “Information gerrymandering in social networks skews collective decision-making”, refers to the concept of information gerrymandering. In case you’re unfamiliar with information gerrymandering, we’ve provided some context below about what it is and why it’s important for students to be aware of.

What is gerrymandering?

Information gerrymandering

Information gerrymandering isn’t just a theory. Stewart et al. identified “extensive information gerrymandering in real-world influence networks including online political discussions leading up to the US federal elections, and in historical patterns of bill co-sponsorship in the US Congress and European legislatures”. We need to be aware that our social networks can be manipulated and even gerrymandered to achieve certain political outcomes without us knowing.

Even though there is a blue majority, a small amount of digital gerrymandering can be enough to change an outcome

Art should prompt questions and feelings and this artwork has been designed to prompt students to reflect on what they see on Twitter, Facebook, Instagram, TikTok, Reddit, YouTube and Snapchat.

It’s critical that students recognise the role social media plays in influencing our views and world perspective. Students should reflect on their own social networks, the topics and views represented and recognise that their views are just one part of a larger picture. As we increasingly get our news from social media, it’s more important than ever that we teach students the skills to seek out information from reputable sources and to critically assess everything they read.

We hope you enjoy this lesson and that it assists you in having this important conversation with your students.
