Digital safety is a pressing concern in an increasingly connected world. In classrooms everywhere, educators face the challenge of supporting young people to learn about cybersecurity and to navigate online risks and the impact of AI tools and social media.
In issue 29 of Hello World, out today for free, educators all over the world share what digital safety and security mean in their classrooms. We hope this new issue will help you to actively empower your learners by equipping them with the understanding and skills to safely navigate our complex digital landscape.
The issue covers questions such as:
Beyond the focus on safety and security, here are three highlights from issue 29:
We also have new podcast episodes coming out over the next few weeks to continue the conversations started in the magazine.
The first episode is another edition of our teacher tips series, where computer science educators and experts from around the globe share practical, actionable tips that you can use in your classroom. In the upcoming episode, teachers will be sharing what works for them to engage students in cybersecurity, protect schools from cybersecurity breaches, and safely introduce generative AI to the classroom.
In the second episode, we’ll talk to Dr. Karla Badillo-Urquiola about her research in online safety in the Global South.

In this article adapted from Hello World issue 18, teacher Babak Ebrahim explains how his school uses a cybersecurity club to increase interest in Computing among girls. Babak is a Computer Science and Mathematics teacher at Bishop Challoner Catholic College Secondary in Birmingham, UK. He is a CAS Community Leader, and works as a CS Champion for the National Centre for Computing Education in England.
It is impossible to walk into an upper-secondary computer science lesson and not notice the number of boys compared to girls. This is a common issue across the world; it is clear from reading community forums and news headlines that there is a big gap in female representation in computing. To combat this problem in my school, I started organising trips to local universities and arranging assembly talks for my Year 9 students (aged 13–14). Although this was helpful, it didn’t have as much impact as I expected on improving female representation.
This led me to alter our approach and target younger female students with an extracurricular club. As part of our lower-secondary curriculum, all pupils study encryption and cryptography, and we were keen to extend this interest beyond lesson time. I discovered the CyberFirst Girls Competition, aimed at Year 8 girls in England (aged 12–13) with the goal of influencing girls when choosing their GCSE subjects (qualifications pupils take aged 14–16). Each school can enter as many teams as they like, with a maximum of four girls in each team. I advertised the event by showing a video of the previous year’s attendees and the winning team. To our delight, 19 girls, in five teams, entered the competition.
To make sure that this wasn’t a one-off event, we started an after-school cybersecurity club for girls. All Computing teachers encouraged their female students to attend. We had a number of female teachers who were teaching Maths and Computing as their second subjects, and I found it more effective when these teachers encouraged the girls to join. They would also help with running the club. We found it to be most popular with Year 7 students (aged 11–12), with 15 girls regularly attending. We often do cryptography tasks in the club, including activities from established competitions. For example, I recently challenged the club to complete tasks from the most recent Alan Turing Cryptography Competition. A huge benefit of completing these tasks in the club, rather than in the classroom, was that students could work more informally and were not under pressure to succeed. I found this year’s tasks quite challenging for younger students, and I was worried that this could put them off returning to the club. To avoid this, I first taught the students the skills that they would need for one of the challenges, followed by small tasks that I made myself over two or three sessions.
For example, one task required students to use the Playfair cipher to break a long piece of code. In order to prepare students for decoding this text, I showed them how the cipher works, then created empty grids (5 x 5 tables) and modelled the technique with simple examples. The girls then worked in teams of two to encrypt a short quote. I gave each group a different quotation, and they weren’t allowed to let other groups know what it was. Once they applied the cipher, they handed the encrypted message to another group, whose job was to decrypt it. At this stage, some would identify that the other group had made mistakes using the techniques, and they would go through the text together to identify them. Once students were confident and competent in using this cipher, I presented them with the competition task, and they then applied the same process. Of course, some students would still make mistakes, but they would realise this and be able to work through them, rather than being overwhelmed by them. Another worthwhile activity in the club has been for older pupils, who are in their second year of attending, to mentor and support girls in the years below them, especially in preparation for participating in competitions.
Other club activities have included a trip to Bletchley Park. As a part of the package, students took part in a codebreaking workshop in which they used the Enigma machine to crack encrypted messages. This inspirational trip was a great experience for the girls, as they discovered the pivotal roles women had in breaking codes during the Second World War. If you’re not based in the UK, Bletchley Park also runs a virtual tour and workshops. You could also organise a day trip to a local university where students could attend different workshops run by female lecturers or university students; this could involve a mixture of maths, science, and computer science activities.
We are thrilled to learn that one of our teams won this year’s CyberFirst Girls Competition! More importantly, the knowledge gained by all the students who attend the club is most heartening, along with the enthusiasm that is clearly evident each week, and the fun that is had. Whether this will have any impact on the number of girls who take GCSE Computer Science remains to be seen, but it certainly gives the girls the opportunity to discover their potential, learn the importance of cybersecurity, and consider pursuing a career in a male-dominated profession. There are many factors that influence a child’s mind as to what they would like to study or do, and every little extra effort that we put into their learning journey will shape who they will become in the future.
