This survey book reviews four interrelated areas: (i) the relevance of
heuristics in problem-solving approaches - why they are important and
what research tells us about their use; (ii) the need to characterize
and foster creative problem-solving approaches - what type of heuristics
helps learners devise and practice creative solutions; (iii) the
importance that learners formulate and pursue their own problems; and
iv) the role played by the use of both multiple-purpose and ad hoc
mathematical action types of technologies in problem-solving contexts -
what ways of reasoning learners construct when they rely on the use of
digital technologies, and how technology and technology approaches can
be reconciled.
