‘The piece that we were looking for’: teachers' collaborative curriculum design for equity-centred biology units

Abstract

ABSTRACT Critiques of current science education reforms call for science curricula that reflect expansive notions of equity in science teaching. This case study explores the experiences of two secondary-school biology teachers in the United States working as a Teacher-Design-Team (TDT) to centre equity through new curriculum materials that they co-designed. Four questions guided the study: (1) How did teachers centre equity in their curriculum design decisions and what concepts of equity did these decisions evoke? (2) How did teachers characterise their process for centring equity in the collaborative design of their biology units? (3) What do teachers describe as outcomes of their work? (4) What did teachers experience as supports – or challenges – in their efforts to design equity-centred units? Key findings include that a strong partnership and shared goals grounded in an equity framework catalysed the teachers’ work; teachers used an emergent ‘three-pronged approach’ to organise their unit planning; teachers’ centring of equity contained many facets; and teachers described multiple benefits from their TDT efforts, including greater job satisfaction and strengthened intention to remain in teaching. These findings have implications for future research and for practitioners who support the work of Teacher-Design-Teams (TDTs), particularly for science curriculum innovations that centre equity.
