Assessing the effectiveness of usability evaluation methods for children

The comparison of three Usability Evaluation Methods (UEM's) is reported with respect to the number of problems uncovered on software products, by children participants. The UEM's compared require different levels of verbalisation of the child that is performing the evaluation. Age of the children, gender, verbal competence, and extroversion level are things that could influence which UEM works best. The outcome of the experiment was that a UEM that requires the children to verbalise a lot is the most effective, and that girls find more problems in the program than boys
