Abstract
This study explores the sources of influence on and the level of coherence of one teacher's beliefs and practices in relation to mathematical problem solving. Rose regularly uses problem solving approaches in her Year 2 class as she believes that this makes mathematics learning meaningful. Her beliefs and practices have been strongly influenced by her own experiences as a learner of mathematics as well as by advice received in postgraduate education and in curriculum documentation. Her beliefs are coherent when explored using a variety of data collection methods.
