Aims and Rationale for the Topic
This discussion group attracted congress participants interested in exchanging ideas and discussing issues and challenges related to mathematics education in schooling systems where large classes (40+ students) are the norm. Large classes are sometimes viewed as limiting students’ opportunities to learn, but the fact that being in a large class is the reality for many students, particularly in developing nations, led the organisers of this discussion group to consider the study of teaching large classes, at both primary and secondary levels, to be a worthy object of research and inquiry.
In contexts where not only are class sizes large, but also teaching resources are frequently limited, it is largely the teachers’ instructional practices that provide the main point of access to mathematics for the learners. Thus this discussion group team have been investigating large class pedagogies (and in particular pedagogies which are predominantly teacher-centred) with a view to how such pedagogies bring mathematical objects of learning into being in the classroom space. To this end we have been working with an analytical framework for studying mathematical discourse in instruction, MDI. MDI is characterised by four interacting components in the teaching of a mathematics lesson: exemplification, explanatory talk, learner participation and the object of learning (goal).
Aims of the DG sessions include identifying, sharing and discussing common key issues in teaching and learning in large classes and exploring the potential of the MDI framework to examine such issues. Through sharing cross-national and cross-phase experiences we aimed both to broaden the base of lessons that the framework might be applied to and to explore ways in which the framework might be developed. Through participants sharing experiences and research interests we hope to explore the potential for future collaborations.
Key Questions and Issues
Key questions to discussed included:
