Abstract Title: Interpreting Card-sorting data with categorization graphs
Abstract: On its 30th anniversary, we are re-examining the seminal paper by Chi et al., which firmly established the notion that novices categorize physics problems by surface features (e.g. incline, pendulum, or projectile motion), while experts use deep structure (e.g. energy conservation or Newtons second law). The paper has been cited over 3000 times in scholarly articles over a wide range of disciplines. Yet, this card sorting experiment's research design and analysis methods are not clear. In replicating the study, we set about looking for a way to compare one categorization to another without reference to some standard categorization set, and in doing so have developed a new method for analyzing card sorting experiments.
