Abstract
The purpose of this study was to investigate the relationship between students'
classroom experiences and their construction of mathematical meanings. Data were
collected from classroom observations and video taping sessions and from subsequent
video-stimulated interviews with 6 students in each of two year 5 classes. Results
discussed here are those from analysis of the interviews. This analysis revealed the
existence of four primary sources by which students determined the meaning or
correctness of mathematical activity: the teacher, intuition, familiarity, and procedural
knowledge. Second, in relation to the social level, the teacher emerged as playing the
most valued role in the sense making and ratifying of procedures or answers.
