title = "Micro-evolution of documentational work in the teaching of the volume of revolution",
abstract = "In this paper, we draw on the documentational approach to analyse the evolution of one experienced secondary teacher{\textquoteright}s work towards the teaching of the topic of “volume of revolution”. He used a range of paper and computer based resources in- cluding the software Autograph. Data were collected in observations of three lessons on this topic taught to two different groups of 16-18 years old students and a follow up interview with the teacher where he was asked to reflect on his choices in these lessons. The findings illustrate teacher{\textquoteright}s documentational work with the used resources, and his schemes of use – aims, rules of actions, operational invariants and inferences – and identify the micro-evolution, namely the small changes and the rationale behind these changes, of these schemes across the lessons.",
