摘要
En 中文
Understanding how cultural mediators and social interaction promote meaningful learning requires that each student's perspective, reasoning, and construction processes be taken into account. In my analysis of the classroom episodes, I consider individual students' progress as they use tools, discuss data distributions, and interact with their teachers and their peers. I argue that data display tools provide a partial context for discussions but do not constrain the students' interpretations or the way they reason about the data. Students' approaches to the mathematical relations discussed in the classroom result rather from the meaning they attribute to the different features of the displays, the teachers' questions, and the evolving interaction with their peers.
