A Computer Experience questionnaire was piloted with 49 children to validate two new scales of measurement, the Thumbs-Up Scale (TUS) and Frequency of Use Scale (FUS). TUS is a VAS (Visually Analogue Scale) designed to measure perceived skill levels. FUS is a Likert scale for measuring how often a device is used or an event occurs. The two scales gained high correlation with their respective validation measures (TUS r=.892, FUS r=.744) indicating that TUS and FUS can be used effectively with children as young as 7 years old.
