As I progress through my 36th year of teaching, I can’t help but reflect on the many changes that have taken place. As a secondary student I did not have a calculator until Year 12. And so I depended on:
Kaye and Laby, 1968. Four-Figure Mathematical Tables. Longman, Aust.
Columns and columns of logarithms, anti-logarithms, sines, cosines, tangents, reciprocals, squares, cubes and the standard normal distribution.
My first calculator was a Novus Scientific (Mathematician) with LED numerals, a 9V battery and Reverse Polish Notation. After 40 years it is still in good working order!
Until Year 12 though I did pages and pages of calculations using logarithms and antilogs. My Year 10 Maths folder (1971) as shown above was meticulously set out.
I show my students these items in the hope that they will also do their best and make the most of their learning opportunities.
