A comparison of think-aloud, questionnaires and interviews for testing usability with children
نویسندگان
چکیده
The paper reports a comparative assessment of 3 usability-testing methods (UTM) involving 45 children aged 8-14 as test-users. The 3 methods were concurrent think-aloud, interview and questionnaire. These 3 UTM ’s require different levels of verbalisation from the children that were performing the evaluation. It was hypothesised that the age of the children, their gender, verbal competence and extroversion level would influence which method works best. The results of this study show that the think-aloud protocol helps identify most usability problems and suggests that girls thinking out loud report more usability problems than boys.
