In this study we present the re-design of a digital task for university students attending to a probability course. The re-design, directed toward the overcoming of specific critical issues highlighted in previous studies, is mainly aimed at providing students (in particular low achievers) with hints and feedback as tools of scaffolding and meta- scaffolding.

This paper is focused on a pilot study involving a group of first year engineering students and concerning the design and implementation of two digital tasks on multiple representations of subsets of the plane. The tasks were engineered in order to provide university students with hints and feedback aimed at scaffolding their work.
