Calculators: A Learning Environment To Promote Number Sense.
Groves, Susie
The Calculators in Primary Mathematics Project in Australia was a long-term investigation into the effects of the introduction of calculators on the learning and teaching of primary mathematics. The Australian project commenced with children who were in kindergarten and grade 1 in 1990, moving up through the schools to grade 4 level by 1993. Children were given their own calculators to use when they wished, while teachers were provided with some systematic professional support. Over 60 teachers and 1,000 children participated in the project. This paper describes some critical features of project classrooms which supported the development of number sense and reports on the results of interviews with 4th-grade children (n=58), approximately half of whom had long-term experience with calculators. Children with long-term experience with calculators performed better on the 12 mental computation interview items overall, the 24 number knowledge items overall, and the 3 estimation items taken individually. Overall, their performance was better on 34 of the 39 items, with the greatest differences in performance in mental computation generally occurring on the most difficult items. Their pattern of use of standard algorithms, left-right methods, and invented methods for mental computation items did not vary greatly from that of the non-calculator children.
