The teaching of codes is an interesting topic that can inspire students and teach them about online encoding and decoding of messages. There are many examples of codes that can be used to teach students, such as the Caesar cipher mentioned in the course. Another example of a historical code is the enigma machine that was created by the Germans to send coded messages during WW2 and how the code was cracked by the British, especially Alan Turing. This typewriter code machine could be studied alongside a HASS topic to explore the War as well as explore encoding and decoding information and how it relates to the cyber world. Another example of an interesting code is the hieroglyphics of Ancient Egypt and how they were used to create ciphers. This can show a way of encoding information where students can represent letters as pictures to protect their message. The Playfair cipher is another example of a code from history. It was created in 1854 and shows letters in a grid omitting one letter of the alphabet. Students could study these ciphers or coded messages and create their own coded message that a partner would then have to decode. This would teach them about how encoding and decoding messages is an important part of cyber safety and ensuring data is protected through encryption. This could be an engaging way that students can understand the role encryption plays in keeping messages and information safe from hackers or people you do not trust.
