Unit 3: Task – Option 2


2. What other interesting examples of codes from history or the modern-day (digital or non-digital) can you find to inspire or support a lesson about encoding and decoding messages?


Some other examples of codes that we can support our lesson about encoding and decoding messages are:


+ Morse Code: Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.

+ WigWag: During the U.S. Civil War, communication on the battlefield was difficult. Although the telegraph was in use, it was not practical on the field as few telegraph lines ran through a battle area. An American telegrapher named Albert Myer developed a new means of communication by waving flags.


+ The Shugborough Inscription: is a sequence of letters – O U O S V A V V, between the letters D M – carved on the 18th-century Shepherd’s Monument in the grounds of Shugborough Hall in Staffordshire, England, below a mirror image of Nicolas Poussin’s painting the Shepherds of Arcadia.


+ True Codes: In a true code, each word is replaced by a codeword or number according to a key. Since many words might be in the message, the key is usually a codebook where someone can look up an English word and find the corresponding codeword, not unlike a dictionary.
