Quantifying the linguistic persistence of high and low performers in an online student forum

Abstract: This work uses recurrence quantification analysis (RQA) to analyze the online forum discussion between students in an introductory physics course. Previous network and content analysis found differences in student conversations occurring between semesters of data from an introductory physics course; this led us to probe which concepts occur and persist within conversations. RQA is a dynamical systems technique to map the number and structure of repetitions for a time series. We treat the transcript of forum co… Show more

“…This analysis is time-costly to do manually, though still fruitful. But a growing number of tools are applied to automatically code text in education research, such as sentiment analysis (Kelley et al, 2018), recurrence quantification analysis (Myers et al, 2019), latent semantic analysis, and others. One avenue of exploration is to use these textprocessing tools to generate multiplex, time-dependent networks showing complex social structure and how it evolves over a course.…”
