Abstract

fetched live from OpenAlex

This article proposes a Bayesian methodology for modelling a virtual learning community, and illustrates one application of the multi-step approach. The article describes metrics and techniques for modelling fundamental variables that constitute a virtual learning community. The variables used for constructing the Bayesian model were drawn from a grounded theory analysis of transcripts of online discussions and an empirical study that used Thurstone analysis to assign weights and rankings to variables based on their comparative significance according to participants in the communities. The results of the Thurstone analysis were then used to infer causality among the variables and to assign the strength of relationships among the variables. Finally, scenario-based reasoning, grounded on practice, was used to query the model and observe its impact on the other constituent variables and how they relate to one major variable of interest learning in virtual communities.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
