Senior Workshops
Code breaking develops skills in
problem solving and data handling and also demonstrates the 'real life'
application of maths. Enigma Project visits enable students to see that
maths does truly exist out side of the classroom, and that there is scope to
continue to study maths beyond GCSE.
Solving codes by frequency analysis involves the handling and interpretation
of data. Looking at the number of ways the Enigma machine can be set up
involves permutations and combinations. Internet codes introduce one-way
functions and factorising.
Hour-long workshops in the classroom introduce these ideas and also give
scope for further investigation. I leave teachers with ideas for
extending some of the topics raised during the presentation and
also 10 copies of the Code Book
CD-ROM. These CDs can be the
basis for further study into the maths and history of code breaking.
