N2 - Word problems are perceived as the most difficult
part of school mathematics. In this paper we present the results of a study,
centered around a nonroutine word problem, involving 25 secondary school
pupils and 19 preservice mathematics teachers. The results showed that while
the pupils used a whole range of available strategies, preservice teachers utilized
almost exclusively the algebraic approach. Though, this approach did not lead
to greater solution success. Then we compared the preservice teachers’ own
problem-solving behavior with the way they evaluated pupils’ solutions. The
obtained findings evoke serious concerns and lead to a number of questions.
