Résumé

The response of problem solvers to a request like ‘Explain your answer’ does not necessarily provide the assurance that the mathematical representation describing a word problem situation is correct. We suggest to compliment a traditional algebraic word problem with a request to establish a mathematical representation generalizing the problem situation and then to justify its derivation of this mathematical representation. Next, we suggest the construction of a valid deductive argument and evaluate the justification. An example executing the suggestions is given.
