Active learning ideas
Algorithms and Echo Chambers explores the invisible forces that shape our online experiences. Students investigate how social media platforms and search engines use data to personalize content, often leading to 'filter bubbles' where users only encounter viewpoints that align with their own. This topic is vital for understanding how public opinion is formed in the digital age.
Activity 01
Assign students roles as 'users' with specific interests and 'algorithms' who must choose which 'content cards' to show them based on past likes. This demonstrates how quickly a user's feed becomes narrow and repetitive.
How can I tell if a website is reliable?
Activity 02
Pairs use different devices or browsers to search for the same controversial or subjective term. They compare the top results and discuss why the order or content might differ based on location or search history.
What is fake news and how does it spread?
Activity 03
Students identify one topic they feel strongly about and brainstorm three sources that might offer a different perspective. They share these with a partner to discuss how following diverse voices changes their understanding of the issue.
How do I identify bias in digital media?
A few notes on teaching this unit
Watch Out for These Misconceptions
Algorithms are neutral and just show me what I want to see.
Algorithms are designed to maximize engagement for profit, which often means showing inflammatory or extreme content. A role play simulating the 'engagement' goal of a platform helps students see the bias built into the code.
I am not in an echo chamber because I see 'both sides' on my feed.
Often, we see the 'other side' only through the lens of people mocking it. A collaborative investigation into 'context collapse' helps students see how algorithms can distort their perception of opposing views.
