Active learning ideas
Algorithms and filter bubbles are the 'invisible editors' of the digital world. In this unit, 1st Year students explore how platforms use data to predict what they want to see next. The NCCA curriculum aims to make students aware of how these systems can narrow their perspectives, leading to 'filter bubbles' where they only see information that confirms their existing beliefs. This is a critical lesson in developing empathy and open-mindedness in a polarized digital landscape.
Activity 01
One student acts as the 'Algorithm.' Other students show 'interest cards' (e.g., Sports, Cats, Gaming). The Algorithm must decide which 'content cards' to give them based on their past choices, eventually showing how the variety of content shrinks over time.
What is an algorithm?
Activity 02
Stations feature different 'points of view' on a neutral topic (e.g., 'Should school uniforms be banned?'). Students must find one argument at each station that they *disagree* with and explain it to their group, practicing seeing outside their bubble.
How do algorithms decide what I see online?
Activity 03
Students describe what their YouTube or TikTok 'For You' page looks like to a partner. They discuss: 'What does this say about what the app thinks I like?' and 'What am I *not* seeing because of this?'
What is a filter bubble and how can I burst it?
A few notes on teaching this unit
Watch Out for These Misconceptions
Algorithms are always right about what I like.
Students often feel the algorithm 'knows' them. Through the 'Algorithm's Choice' simulation, they see that it's just a mathematical guess based on limited data, which can lead to a repetitive and narrow experience.
Everyone sees the same search results or social media feed.
Many students assume the internet is a universal experience. Comparing search results for the same term on different devices in class quickly surfaces the reality of personalization and filter bubbles.
