?:abstract
  • This article draws on process data from a computer-based large-scale program, the Programme for International Assessment of Adult Competencies (PIAAC), to address how sequences of actions recorded in problem-solving tasks are related to task performance and how feature sequences are identified for different groups. The purpose of this study is twofold: first, to explore and detect action sequence patterns of features that are associated with success or failure on a problem-solving item, and second, to mutually validate the results derived from two feature selection models. Motivated by the methodologies of natural language processing and text mining, we utilized n-gram model and two feature selection methods, chi-square statistic (CHI), and weighted log likelihood ratio test (WLLR), in analyzing the process data at a variety of aggregate levels. It was found that action sequence patterns significantly differed by performance groups and were consistent across countries. The two feature selection approaches resulted in a high agreement of feature identification. (xsd:string)
