Abstract

fetched live from OpenAlex

O uso dos mundos virtuais vem se expandindo no cenário educacional, assim como a gama de possibilidades de pesquisas relacionadas a estes. Este artigo buscou explorar a viabilidade da aplicação de mineração de dados educacionais (MDE) nos mundos virtuais, para identificar possíveis padrões dos usuários e permitir alterações no planejamento pedagógico. Um estudo de caso foi realizado com um laboratório virtual de química no OpenSim, em que foram simuladas interações com dados sintéticos e analisados por meio da tarefa de regras de associação com o uso do algoritmo Apriori. Os resultados demonstraram a viabilidade da proposta, sendo possível o uso de MDE dentro dos mundos virtuais para identificar padrões de comportamento dos usuários.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
