Maarten Dolk http://www.fi.uu.nl/nl/medewerkers/medewerkers/medewerker63.html gave an interesting talk about getting student teachers to develop narratives about events as a tool to construct meaning about mathematics education and to bridge the divide between theory and practice.

They showed a video clip from the classroom and asked six people to comment on it. Despite them running it several times, people still disagreed on what was physically happening (was that child counting in fives or was he really counting in tens) and what the children were doing (building a tower of Unifix cubes or measuring a desk). One story, many interpretations.
