Personal Identity and Online Communities

How has the diffusion of online communities changed how their users construct, view, and define their identity? In this paper, we choose to approach this issue by considering two particular philosophical problems related to personal identity: 1) The Characterization Question, namely “which actions, experiences, beliefs, values, desires, character traits, and so on can we attribute to a given person?” 2) “How do self-other relations affect the ethical implication of identity construction?” To ...

From figural to theoretical control (and back): a first proposal for framing the interplay between different controls

Grounding on Fischbein’s studies, our work is intended to deeply investigate the systems of control which influence the dialectic between the figural and the conceptual component of figural concepts. We propose a first attempt for characterizing the systems of control by introducing a fine-grained distinction between three dimensions: visual, spatial, and theoretical. This theoretical frame is used for analyzing some excerpts from a case study which involve graduated students in Mathematics, ...

Did you know you can draw a huge number of infinite heights? The students’ realization tree of the heights of a triangle

In this paper we report on the analyses of the mathematical discourse of 7th-grade students about the solution of a task on the recognition of the heights of a triangle. Our aim is to describe through the commognitive lens the realizations that appear in the mathematical discourse of the classroom and to observe possible interactions between them. For this purpose, we construct and compare the expected and the actual students’ realization trees, showing the richness of the realizations addres...
