This paper presents an exploration of conversation in a single episode of whole-class work in a Year 12,all girls' Calculus class. The analysis is cast in terms of Habermasian communicative competence, which requires students to evidence critical thinking and the ability to express their views. Favourable learning outcomes in the class are explained by the teacher's mode of questioning, cooperative endeavour by students, the instructional sequence and use of technologies including the graphics calculator. The circumstances of problematic outcomes are also identified.
