题目：Reconnecting Data and Chance

摘要：For the past 15 years, pre-university students in many countries including the US have encountered data analysis and probability as separate, mostly independent strands. Research suggests, however, that some of the difficulties students have in learning basic data-analysis skills stem from poor understandings of probability. I describe our recent efforts to develop and test classroom materials to support middle-school students in coming to see the "data in chance" and the "chance in data". Central to our approach is a new modeling and simulation capability that we built into TinkerPlots 2.0. Our activities employ an iterative model-fit process in which students evaluate successive theories by collecting and analyzing data. As distribution features become a focal point of students' explorations, signal-and-noise components of data become visible as variation around an "expected" distribution in repeated samples. An important part of students' learning experiences, and one enhanced through visual aspects of TinkerPlots, is becoming able to see things in data they were previously unable to see.
