Last update:

Paper Ladder is a low-cost, light-weight, and paper-based variant of the Sticky Ladder rating scale (Airey et al., 2002) to collect children's preference in user studies. This paper version revamps the original, effective but arguably impractical evaluation method by making it more accessible to researchers.

Pilot Study

We conducted a longitudinal pilot study, where 45 second-grade students (on average, 7 years old) used Paper Ladder to rate their preference of different types of correctness feedback in a math app for touchscreen tablets (Figure 1). Results suggested that it could be a valuable instrument for conducting user studies with young children. Read the following extended abstract and watch the video for further details.
