Lack of access to devices presents teachers with challenges in any setting. In schools, money is often limited and digital technology may not be the priority when buildings need maintenance or libraries need replenishing. This issue is particularly important when the very subject you teach relies on and relates to devices that you may have limited or no access to.

It must be frustrating for teachers in this situation to see marketing campaigns from companies showing how their curriculum offering will use the very latest in robotics, AI, or media production, when the teachers’ reality is that they don’t have anything like the means or resources to deliver this. 

Fortunately there are approaches that can help. Below I outline some of the ways we are working with teachers to make the teaching of computing and digital literacy less resource-heavy and more accessible and equitable. 

Schools in Kenya: A case study 

Our work with Kenyan teachers has brought the access issue into sharp focus for us. We are currently developing free resources to deliver the Kenyan curriculum to schools in Mombasa and the Frontier Counties. There are big contrasts both between and within these two areas of the country. Some schools are well equipped with digital technology, while others have very little access to any computing devices; in these schools, smartphones play a crucial role.

With that in mind, the curriculum resources we develop suggest class activities that make the most of limited devices, such as the use of projected demonstrations. We also provide a step-by-step guide to computing tasks, with screenshots, to guide learners through the tasks conceptually. This ensures learners understand the process and can apply their new knowledge once they gain access to the necessary devices. 

We make these resources available online and in downloadable documents. This means the resources can be taken offline and taught in places without stable internet connection. We are also careful to limit file sizes, to make downloads more accessible. Wherever possible, our resources are device-agnostic, so that they can be accessed on a wide range of devices, including personal devices such as mobile phones.

As well as tailoring curriculum resources, we have also adapted our teacher training to make it more accessible for people with less experience of using computing devices. For example, during a recent project coaching community trainers in Mombasa, we emphasised activities that improve digital skills on various devices. This meant that when passing the training on to other teachers, the community trainers had a broader set of skills across a wider range of devices.

Unplugged activities

Even computing-specific concepts such as a programming construct can, to a degree, be taught with very limited access to devices. Unplugged activities, where no digital technology is required, can be used to introduce fundamental concepts such as sequencing and repetition.

For example, you can ask learners to recognise patterns in repeating sequences of colours and identify how to describe the sequences without repeating the colours many times. While it is good practice to link the learning from an unplugged activity back to a plugged activity, students will still benefit when that is not possible. 

Emulators 

There are also a significant number of devices which offer online emulator apps that mirror the functions of the physical device. Consider Bee-Bot floor robots, which can be relatively expensive to purchase and may get damaged in a classroom. If you don’t have the physical device, its emulator app provides a similar experience.

Similarly, the micro:bit, a versatile microcontroller for young people, can be emulated in the MakeCode programming environment, including all its buttons and sensors. There are also numerous emulators which enable you to make and test your own circuits using a variety of hardware platforms. 

What do you actually need? 

Sometimes it can be helpful to look up what devices you actually need — they might not be as expensive as you think. General-purpose, single-board computers such as Raspberry Pi can be bought new for less than £25, and more powerful models still under £50.

Similarly, microcontrollers such as Raspberry Pi Pico, micro:bit, or Crumble, range from about £5 to £20 per device. Accessories such as LEDs, jumper leads, motors, and buzzers are also reasonably priced. They can be a relatively low-cost entry into physical computing and robotics, especially if you pair them with craft materials or share devices between students.

Make the most of it 

However limited your access to devices is, I encourage you to:

• Look out for partners or solution providers that prioritise inclusivity and accessibility in their resources
• Consider whether you can make activities accessible on a wider range of devices and use what students may already have (check out the OctoStudio app for smartphones for example)
• Use unplugged activities, and relate them back to plugged devices when possible
• Look up devices which might be more affordable than you realised
