EXPLORANDO TEMAS COTIDIANOS PARA O ENSINO DE QUÍMICA: COMPREENDENDO A QUÍMICA DOS DESODORANTES
Bibliographic record
Abstract
Esse trabalho propõe uma sequência didática, com o objetivo de promover a discussão de conceitos de química através de produtos que fazem parte do cotidiano dos alunos, como os desodorantes. A sequência proposta visa: (1) instigar o interesse dos alunos e (2) facilitar o entendimento de conceitos abstratos e complexos com o uso de linguagem acessível, experimentação em sala de aula e o emprego de ferramentas digitais paradidáticas.A sequência apresentada foi aplicada e validada a partir de debate e questionário avaliativo com uma turma de 1° ano do ensino médio de uma escola pública do estado do Rio de Janeiro e levou em consideração as opiniões dos estudantes e obedece à diretrizes estabelecidas pelo Ministério da Educação quanto à transdisciplinaridade e estímulo ao pensamento crítico.

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.
