Both formal and informal learning appear to be well-defined in educational discourse, in contrast with non-formal learning which is less clearly articulated. This lack of clarity around non-formal learning has consequences for its recognition by teachers and learners. To contribute to…

Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

Although research has always related e-portfolios to self-regulated learning, recently agency, which includes individual, relational, and contextual domains, has also been highlighted. Likewise, agency has been explored in technological environments that support collaborative and co-design learning processes. This study, investigating the…
