Perceiving the General: The Multisemiotic Dimension of Students' Algebraic Activity
Radford, Luis; Bardino, Caroline; Sabena, Cristina
Journal for Research in Mathematics Education, v38 n5 p507-530 Nov 2007
In this article, we deal with students' algebraic generalizations set in the context of elementary geometric-numeric patterns. Drawing from Vygotsky's psychology, Leont'ev's Activity Theory, and Husserl's phenomenology, we focus on the various semiotic resources mobilized by students in their passage from the particular to the general. Two small groups of Grade 9 students are investigated through a four-dimensional analysis: video, audio, transcripts, and written material. The resulting qualitative analysis shows how discourse, gestures, actions, and rhythms orchestrate one another and how, through a complex and subtle coordination of them, the students objectify different aspects of their spatial-temporal mathematical experience.
