Abstract Title: Quantifying the Linguistic Persistence of High and Low Performers in an Online Student Forum
Abstract: Using network and content analysis, we 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. This work uses recurrence quantification analysis (RQA) to analyze the online forum discussions between students. RQA is a dynamical systems technique to map the number and structure of repetitions for a time series. Here, we treat the transcript of forum conversations as the time series to investigate. We use RQA to characterize the forum behaviors of high and low scoring students, such as their percentage of recurring topics and persistence of discussing a topic over time. We quantify how high scoring and low scoring students use online discussion forums and test whether different patterns exist for these groups. This work is the first adaptation of recurrence quantification methods from the field of psychology for physic education research.
