Course content

5 sections100 lectures3h 53m total length
  • Introduction2:05

    Here are the fundamental questions we'll answer together:

    Why do you see what you see online?

    Who's actually deciding what appears in your feed?

    What are these platforms actually optimised for?

    What's their goal when they design their systems?

    How does your own behaviour shape the digital environment that surrounds you?

  • Algorithmic Curation0:55

    In this video you will learn to notice that your feed is curated rather than random. You will explore how platforms select content for you, why they make these choices, and how this quiet filtering shapes your information environment. You will also begin to question what criteria guide these decisions, which prepares you for the next stages of the course.

  • What Is a Recommendation Algorithm?1:12

    In this video you will learn what a recommendation algorithm actually is and how it works at a basic level. You will explore the role of behavioural data in shaping predictions, how platforms test what engages you, and how your actions feed back into the system. You will also learn to recognise the feedback loop between your behaviour and what the platform shows you next.

  • The Data Being Collected1:42

    In this video you will learn what types of behavioural and contextual data platforms actually collect about you. You will explore the difference between active signals like clicks and comments, and passive signals like scrolling, pausing, and viewing time. You will also learn how everyday details such as device, location, and time of day contribute to the profile that gets built about you.

  • Practical Activity 1: The 2 minute Scroll1:27

    In this video you will carry out a short observation exercise on your own social media feed. You will learn to identify how much of what you see comes from people you chose to follow, how much is advertising, and how much is recommended content. You will also record simple data from your own scrolling behaviour, which will be used in the next part of the course.

  • What Are Algorithms Optimised For?1:32

    In this video you will learn what social media algorithms are actually optimised for. You will explore the difference between engagement and other possible goals such as accuracy, importance, balance, or wellbeing. You will also begin to understand why these objectives can conflict, and how this explains the type of content that rises to the top of your feed.

  • What Kind of Content Drives Engagement?2:20

    In this video you will learn what types of content tend to generate the highest engagement online. You will explore the role of strong emotions, novelty, confirmation of existing beliefs, visual formats, and message simplicity in driving interaction. You will also learn which kinds of content tend to be deprioritised by engagement systems, such as nuanced, complex, or text-heavy material.

  • Your Behaviour Trains the Algorithm1:32

    In this video you will learn how your own behaviour trains recommendation systems over time. You will explore how engagement signals, including negative reactions, shape what the platform shows you next. You will also learn how repeated interactions create a self-reinforcing feedback loop that narrows your digital environment, and why engagement does not always reflect what is healthy or valuable for you.

  • PRACTICAL ACTIVITY 2 - Engagement Audit2:11

    In this video you will carry out a reflective audit of your own engagement history on a platform you use. You will learn how to review your recent likes, shares, and comments, and categorise them by emotion and topic. You will also start to notice patterns in what you have been rewarding with your attention, and compare these patterns with what you actually want to encourage in your feed.

  • The Attention Economy1:36

    In this video you will learn how social media platforms make money and why they are free to use. You will explore the shift from traditional media business models to the attention economy, and how advertising drives platform behaviour. You will also learn to distinguish between the user as a participant and the advertiser as the paying customer, and why this changes what platforms prioritise.

  • The Attention Economy Business Model2:15

    In this video you will learn how the advertising business model of social platforms actually functions step by step. You will explore how user attention and behavioural data become commercial assets, how targeted advertising works in practice, and how time spent on the platform links directly to revenue. You will also learn how this creates a self-reinforcing commercial cycle between data, engagement, and profit.

  • The Cost of Free1:47

    In this video you will explore both the benefits and the hidden costs of social media use. You will recognise what these platforms genuinely offer in terms of connection, access, and creative tools, and what users trade in return through time, attention, personal data, and influence over their information environment. You will also begin to reflect on what it means to make informed choices about this trade.

  • CASE STUDY - Instagram's Algorithm Evolution2:40

    In this video you will learn how Instagram’s algorithm and design priorities have shifted over time. You will explore key changes such as the move from chronological feeds to algorithmic ranking, the evolution of the Explore page, experiments with visible metrics, the push toward short-form video, and the rise of recommended content from accounts you do not follow. You will also see how each change reflects a gradual move toward stronger engagement optimisation.

  • PRACTICAL ACTIVITY 3 - Time Audit1:36

    In this video you will examine your own screen-time data and compare it with your estimated usage. You will learn how to check your device’s activity reports, calculate your actual time spent on social platforms, and reflect on how those hours add up across a week or a year. You will also consider whether this time investment aligns with your intentions and priorities.

  • Why You See What You See2:22

    In this video you will learn how personalisation creates different information environments for different users on the same platform. You will explore how algorithmic feeds replace shared media experiences with customised ones, and why this makes it harder to have common reference points for news and events. You will also be introduced to the idea of personalised information bubbles, which will be developed further in the next module.

  • Signals the Algorithm Uses2:08

    In this video you will learn what types of signals recommendation systems use to decide what to show you. You will explore the role of your past behaviour, the behaviour of similar users, recency, content format, early engagement speed, your social network, and contextual factors such as time, device, and location. You will see how these signals combine to shape the specific feed you see at any given moment.

  • The Illusion of Choice1:28

    In this video you will learn how algorithmic filtering shapes the choices you think you are freely making. You will explore the difference between selecting from a curated feed and having access to the full range of available content. You will also examine how this creates an illusion of control, where personal choice operates within limits set by engagement-driven systems.

  • CASE STUDY - YouTube Autoplay1:56

    In this video you will analyse YouTube’s autoplay feature as a concrete case study of how platform design reduces conscious choice. You will explore how default continuation replaces deliberate decision-making, how this shifts responsibility onto the user to stop rather than choose, and how small design features can significantly extend time spent on a platform. You will also be introduced to the idea of attention architecture through this specific example.

  • PRACTICAL ACTIVITY 4 - Feed Diversity Check1:48

    In this video you will complete an assessment of your own information environment. You will identify your main sources of news and content, the topics that dominate your feed, and the perspectives you regularly encounter. You will also reflect on what may be missing from your information diet, and assess how diverse or narrow your overall exposure currently is.

  • The Digital Diet Assessment1:46

    In this video you will learn how to assess your digital information diet using four dimensions: quantity, quality, impact, and alignment. You will explore how much time you spend consuming digital content, what types of material you engage with, how this consumption affects your wellbeing, and whether it supports your stated goals and values. You will be introduced to a structured way of reviewing these four areas step by step.

  • PRACTICAL ACTIVITY 5: Comprehensive Digital Diet Audit2:09

    In this video you will complete a full audit of your digital information diet using a structured framework or worksheet. You will document how much time you spend on different platforms, what types of content and topics dominate your use, how this activity actually makes you feel, and how it affects areas such as sleep, work, and relationships. You will also compare your current digital habits with your stated values and life goals, to see where they are aligned and where they conflict.

  • The Cost of "Common Patterns"1:55

    In this video you will review the common patterns that tend to emerge after completing a digital information diet audit. You will recognise typical gaps between estimated and actual time use, between stated interests and real consumption, and between values and everyday habits. You will also reflect on patterns such as passive use, autopilot behaviour, and returning to platforms despite negative emotional effects.

  • Module 1 Final Reflection1:17

    In this video you will reflect on your key insights from the module. You will identify what surprised you, what felt uncomfortable, what gave you hope, and what single idea you want to carry forward into your future digital habits. You will also capture these reflections in writing as part of your learning process.

  • No IT skills are needed

Description

This course teaches you how to think clearly in today’s digital information environment.

Every day, platforms decide what you see, algorithms reward engagement over accuracy, and misleading claims spread faster than careful analysis. This course shows you how that system works and how to operate inside it without being manipulated by it.

You will learn how social media platforms are designed, how algorithms rank and amplify content, and why certain posts, videos, and narratives keep appearing in your feed. You will then develop practical critical thinking skills to evaluate claims, statistics, sources, and media before you accept or share them.

This is not a theory-heavy course. It is practical, structured, and action-based. Each module includes short explanations followed by exercises that help you apply the skills immediately to real online content.

The course builds step by step. You first understand the system. Then you learn how it influences perception. Then you practise analysing claims and spotting manipulation. Finally, you build simple habits you can use every day.
