Analogy: A comparison between things that have similar features, often used to help explain a principle or idea (Cambridge University Press, 2017). Computing subject content can often seem abstract for teachers, let alone for 10CS3 in a Friday afternoon computer science lesson.
A well-chosen analogy, however, can help pupils make sense of these topics within the framework of their own experiences. Science and maths teachers have been using analogies for years and this session aims to highlight 80 parallel descriptions you could use to support your teaching. If it was good enough for Plato and Aristotle then it should work with 10CS3!
