  In recent years, digital technologies have grown in many ways. As a result,
many school-aged children have been exposed to the digital world a lot.
Children are using more digital technologies, so schools need to teach kids
more about cyber security and online safety. Because of this, there are now
more school programmes and projects that teach students about cyber security
and online safety and help them learn and improve their skills. Still, despite
many programmes and projects, there is not much proof of how many schools have
taken part and helped spread the word about them. This work shows how we can
learn about the size and scope of cyber security and online safety education in
schools in the UK, a country with a very active and advanced cyber security
education profile, using nearly 200k public tweets from over 15k schools. By
using simple techniques like descriptive statistics and visualisation as well
as advanced natural language processing (NLP) techniques like sentiment
analysis and topic modelling, we show some new findings and insights about how
UK schools as a sector have been doing on Twitter with their cyber security and
online safety education activities. Our work has led to a range of large-scale
and real-world evidence that can help inform people and organisations
interested in cyber security and teaching online safety in schools.
