This design-based study addresses the issue of how to digitally support students' problem-
solving by providing heuristics, in the absence of the teacher. The problem is that, so far …

In scaling up the use of heuristic trees to facilitate students' mathematical problem solving,
we developed a design course and design protocol for heuristic trees. However, designing …

This research investigates the design of heuristic trees in supporting pre-university students
in mathematical reasoning, as well as finding and formulating proofs within Dutch secondary …

Compression of mathematical objects, procedures and statements could play a major role in
successful problem solving. We report on a study in which we aim to design an instrument …

There is a broad consensus on the importance of problem solving both as a learning goal
and as a teaching method. Problem solving is an essential academic skill. However …
