Can ‘microtutorials’ boost online safety?

Jul 28th '23

Timely, targeted and short, ‘microtutorials’ are increasingly common for those of us who use smart devices. When  you download an app, you will often be walked through how to use it. You are shown the key features. You might practise using them (like how to ‘swipe’ to change screen) 1. You receive ‘microdoses’ of teaching – tiny tutorials to build your awareness, capability and motivation to use the feature.


Low engagement with safety features is a problem in online safety. Office of Communications (Ofcom) are interested in whether these new tools could help rapidly engage and educate users on the features available.



The behaviour Ofcom targeted was reporting of potentially harmful content. Around seven in ten users report experiencing harmful online content or behaviour in the last four weeks. Reporting helps highlight this content to platforms.


Ofcom’s Behavioural Insight specialists previously ran an experiment investigating the effect of prompts and nudges to encourage reporting. In contrast to those ‘in the moment’ nudges, microtutorials take a different approach – ‘boosting’ reporting by building users’ capabilities to report.


Ofcom experiment is grounded in boost theory. Unlike nudges, which use choice architecture to guide a decision ‘in the moment’, boosts foster competence, mainly through skills, knowledge and decision tools 2.  The theory is that boosts have the potential for lasting effects beyond the moment of choice.


But boosts may not just build capability. The COM-B model, which Ofcom has discussed before, tells us that a change in capability can influence motivation to take action. Microtutorials aim to enrich users’ capabilities, but in principle   can also influence motivation and ultimately behaviour.


What boosts a boost?

Ofcom designed three microtutorials on the features of a mocked-up video-sharing platform (VSP, of which examples include Snapchat and TikTok): a static version, a video version and an interactive version.



Three screens with images of the interface annotated to indicate the function of the buttons and processes where multiple inputs required



60-second video showing a user inside the platform working through the functions of the buttons and processes (included voiceover commentary)



Multiple screens walking the user through the interface, requiring them to perform an action e.g. ‘click the flag to report the content’ to progress


The static version aimed to test a microtutorial at its simplest. It is quick with no-frills.


The video microtutorial tests whether a more engaging user experience increases effectiveness. The prevalence of video-sharing platforms indicates the appeal of this format.


The interactive version builds on the insight from Ofcom’s serious game trial which found that interactivity enhanced learning. It also builds on the growing body of educational research that suggests that active learning is more effective than passive learning 3.


Ofcom’s experiment

Participants were randomly allocated to take one of the microtutorials or no microtutorial (the ‘no information’ control group).  They did not have the option to skip the microtutorial. They then watched six videos – three neutral, three containing potentially harmful content – in randomised order. Participants were given no specific task other than to browse the videos and interact with them as they normally would. There was no instruction to report or carry out any other activity. Ofcom wanted to see the effect of the microtutorial on general browsing behaviour.


Additionally, Ofcom asked users expressly to complete a report on a further video. This section of the experiment  explicitly tested the effect of the microtutorial on capability.


The experiment concluded with questions on participants’ views on VSPs, reporting and their specific microtutorial.


Five insights


    1. All the microtutorials significantly increased reporting when specifically prompted. Microtutorials can clearly play the limited role of boosting capability 4.
    2. Turning to whether they can also build motivation, with no microtutorial, participants did  not report much – only 4% reported at least one potentially harmful video . That means only 4% who saw a potentially harmful video were motivated to report it . Even the remarkably basic, static microtutorial has a significant impact – 9% reported  at least one potentially harmful video 5. Simply getting users to pause, pay attention and briefly interact with the information increased use of the safety feature.
    3. The video and interactive microtutorials were even more effective – 16% in the video group reported at least one potentially harmful video, 23% of the interactive group  . These are large effects 6. They suggest that microtutorials can boost behaviour – not just capability. The success of the interactive version compared to the video also tells us that, at least in the experimental setting, interactivity trumps user-experience in driving impact . Practising a behaviour, even just once, can enhance learning and motivation to enact that behaviour.



  1. Driving up reporting can risk  increasing spurious reports which place a burden on platforms. However, the microtutorials did not increase reporting of neutral content relative to the ‘no information’ group.
  2. The video and interactive microtutorials had positive spillover effects. Participants became more engaged with the platform all-round – they did more liking, disliking, commenting 7, etc. And they told us that they gained greater confidence in using video sharing platforms more generally – not just the one they used in the experiment 8.



In the real world

It is important to remember the limitations of this kind of study. Participants know they are in an experiment and may not act how they normally would. T his experiment cannot teach us about the ongoing impact of microtutorials. Ofcom cannot yet say whether they have the lasting effects that boost theory suggests.


Nevertheless, the experiment suggests that microtutorials can play a role in ‘activating’ users to engage with safety measures, and gives insights into what makes them work. It is striking that even very basic microtutorials have a significant effect, and that impact can be enhanced with interactivity.


There is further potential. The microtutorials Ofcom designed were not polished nor targeted at specific features. There is considerable scope to improve the user experience and reduce their duration. This could improve their effectiveness while also reducing the interruption to the user journey.


On the other hand, in contrast to most real-world examples, Ofcom participants did not have the option of skipping the microtutorial. This allowed us to learn about their relative effectiveness but does mean Ofcom do not know how many users would engage with the microtutorial if they were optional. Ofcom is interested to find out .


Help Ofcom learn more

Developing evidence on the promise offered by microtutorials has helped us build knowledge on the range of online tools available to encourage safety behaviours. Ofcom want to generate more evidence on the impact of ‘boost’ interventions. Get in touch about related research or if you would like to explore a trial with us.

  3. In experimental settings, there’s a risk of social desirability bias – participants might report more because they pick up a sense that that’s what the trial is looking at. To avoid this, the microtutorials taught all the features of the platform (play, pause, like, dislike, comment, share, report, skip) so that no specific feature was seen to be encouraged.
