Triggers of contingency in mathematics teaching

Abstract

Our research in the last decade has been into classroom situations that we perceive to make demands on mathematics teachers' disciplinary knowledge of content and pedagogy. Amongst the most visible of such situations are those that we describe as ‘contingent’, in which a teacher is faced with some unexpected event, and challenged to deviate from their planned agenda for the lesson. Our findings and the associated grounded theories have been open to enhancement and revision as new classroom data has been gathered. In this article, we propose a classification of the origins of contingent classroom episodes: namely the students; the teacher him/herself; and pedagogical tools and resources. This classification extends and elaborates our original conception of ‘contingent’, in response to more recent data

Teachers Knowledge Mobilized in Geometry Lessons and Contingency Situations

“…In this way, future teachers, upon knowing those situations, can expand the possibilities of understanding teaching practice, highlighting contingency moments. Rowland, Thwaites, and Jared (2015) carried out a study specifically on the contingency dimension, which guided this research. They investigated the factors that can trigger those contingency moments, namely: the students, the teachers or the resources.…”

“…According to the authors, the teacher can either ignore it; or recognize the student's idea, but not incorporate it into the discussion; or recognize and incorporate the idea into the classroom discussion. Students' ideas can appear in three ways: (a) when answering a question the teacher asked; (b) when responding spontaneously in a discussion; (c) when answering incorrectly, either to a question or a discussion (Rowland, Thwaites, & Jared, 2015).…”

Values and Valuing in Mathematics Education

“…In summary then, this study sort to reveal the values underlying the reasons for the five teachers' first noticing and then responding at key points in lessons that were designed to teach the mathematics of polygons. In this chapter 'key point' refers to both routine and non-routine situations, those that might have been expected by the teacher and those that were unexpected (see Bishop 2008b;Rowland et al 2015). Content analysis was adopted as the data analysis procedure for the study (Merriam 2009).…”

The Knowledge Quartet in the Light of the Literature on Subject Matter and Pedagogical Content Knowledge

“…Connection includes the selection of mathematical topics, the connections between the decisions taken, the sequencing of topics of instruction within and between lessons, and the ordering of tasks and exercises (Rowland, Thwaites & Jared, 2015;. Turner (2007) indicates that anticipation of complexity, recognition of conceptual appropriateness for students and making connections are significant components of this unit.…”
