Micro-Analysis of Collaborative Processes that Facilitate Productive Online Discussions
Bibliographic record
Abstract
Studying time with statistics can help shed light on cause-effect relationships in large online data sets and address three sets of research questions regarding sequences, time periods, and influences of phenomena across different time-scales. As such studies face many analytic difficulties (related to the data, dependent variables, or explanatory variables), this chapter shows how the method of Statistical Discourse Analysis (SDA) addresses each of them. Then, the authors apply SDA to three online data sets: (a) 183 participants’ 894 messages in a mathematics forum without teacher moderation, (b) 17 students’ 1,330 messages in a 13-week graduate course, and (c) 21 students’ 252 messages across 8 weeks during a hybrid university course. Findings include (a) significant relationships between non-adjacent messages, (b) explanatory models of statistically-identified pivotal messages that distinguish distinct time periods, and (c) effects of larger phenomena on smaller phenomena (e.g., gender on message characteristics) and vice-versa (extensive summary on time periods).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
