Abstract
Sixteen Form 1 and 2 students worked in pairs to solve problems involving
decimal fractions. Their discussions were analysed to see what kind of
conflicts led to learning about the meaning of decimals. Useful conflicts arose
from those written into the problems, differences between calculator results
and expectations, discussions with a peer, and differences between out-of-school
experience and calculations. The most profitable conflicts could be
classified as those that brought about what Piaget called beta reactions.
