Teacher And Students' Joint Production Of A Reversible Fraction Conception, Ron Tzur
Teacher And Students' Joint Production Of A Reversible Fraction Conception, Ron Tzur
Ron Tzur
Within a constructivist perspective, I conducted a teaching experiment with two fourth graders to study how a teacher and students can jointly produce the reversible fraction conception. Ongoing and retrospective analysis of the data revealed the non-trivial process by which students can abstract multiplicative reasoning about fractions. The study articulates a conception in a developmental sequence of iteration-based fraction conceptions and the teacher’s role in fostering such a conception in students.
Distinguishing Two Stages Of Mathematics Conceptual Learning, Ron Tzur, Marty Simon
Distinguishing Two Stages Of Mathematics Conceptual Learning, Ron Tzur, Marty Simon
Ron Tzur
In this theoretical article, we distinguish two stages of learning a new mathematical concept – participatory and anticipatory. We use a recently developed mechanism for explaining mathematical conceptual learning – reflection on activity-effect relationship – as well as von Glasersfeld’s tripartite model of a scheme, to explain qualitative distinctions between the two stages. We use this distinction to explain why instructional interventions (including inquiry-based approaches) may not bring about the intended instructional goals.
