Hello World issue 20 out now!
“Have you tried switching it off and on again?” “The Wi-Fi must be down!” “How come I can’t see the cloud up in the sky?” Computing systems and networks is one of those computer science topics in which misconceptions abound, and learners can struggle to grasp its abstract concepts. This issue offers ideas and inspiration for unpacking those tricky concepts with your learners. We discuss the research into different approaches to teaching networking, before seeing some of those methods in action. We explore the merits of inviting a network manager into your classroom, profile a number of different network simulator tools, and delve into ways to make networks concrete for primary learners.
Over the last three years, we’ve seen more than 7 million students around the world put down their schoolwork and take to the streets to demand climate change action. Could technology be the answer? This issue explores the interaction between sustainability and computing, from how we can interact with technology responsibly to its potential to mitigate climate change. We delve into the research behind device-repair cafés and see repair put into action by a student in Malaysia for his local community, along with a deep dive into the question of technology obsolescence. We also share young people’s ideas for how technology can be used for good, showcasing sustainability-themed student projects and a school-based COP that was inspired by the annual UN conference.
Cybersecurity threats are increasing and changing all the time; teaching students how to protect themselves is vital. This issue spans the ethics and legalities of hacking, advice about teaching cybersecurity to primary-school children, and an introduction to quantum cryptography. We also share some fantastic ideas for making this topic as hands-on as possible, including through using network robots, using tools and techniques used by real-life penetration testers, and by taking part in a ‘capture the flag’ competition.
Not only is health and well-being an engaging context to bring computing to life for your students, it’s also never been more relevant as we emerge from periods of isolation and pay more attention to personal health. This issue spans articles on teacher and student well-being, to computing projects addressing air pollution and health, to real-life research at the intersection of computing and the healthcare industry.
We are living in an increasingly data-driven world. From tracking our fitness data, to analysing coronavirus infection rates, to choosing to watch TV shows ‘selected for you’ by Netflix, data is everywhere. This issue focuses on data science and data literacy; it is full of teaching ideas and inspiration to help you and your students use data to make decisions and to make sense of the world.
Due to a shortage of teachers with computer science degrees, switching specialisms is a common route to becoming a computing educator. But why do some teachers choose to change subjects? In issue 15 of Hello World, we hear from five people who have made the switch. They tell us about the challenges they have faced, as well as the joys of teaching young people how to create new things with technology.
From counting penguins in Antarctica to orienteering with a GPS twist, great things can happen when young people get creative with technology outdoors.
How has computing education changed over the last few months? And how will the coronavirus pandemic affect education in the long term?
