Exploratory learning, 1967
A school in Dagenham was loaned seventeen Summa 20 and six Divisumma 24 [calculators] in an experiment to teach maths. The Olivetti machines replaced log tables and slide rules for two groups of 11 to 15 year olds. The first group were given 2.5 hours tuition to learn multiplication. Whereas the second group were left to discover for themselves how to use the machines. The second group learned the quickest. British Olivetti Ltd newsletter, 1967
