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.}, }
