Abstract

fetched live from OpenAlex

A dissertação discute a abordagem de conceitos de construção geométrica nos livros didáticos dos anos finais do ensino fundamental do Brasil e Canadá. Para isso, pesquisamos o papel da construção geométrica na educação, da utilização dos livros didáticos e a relevância da análise comparativa na área. As fontes utilizadas foram os documentos oficiais: orientações curriculares brasileiras (PCN) e canadenses (the Ontario Curriculum); quatro coleções de livros: Projeto Teláris, Matemática na Medida Certa, Nelson Mathematics e Math Makes Sense; guia do livro didático (Brasil e Canadá). Usando a análise documental como modalidade de pesquisa, buscamos responder à pergunta: como os saberes relacionados ao desenho geométrico são representados em cada coleção e quais as principais diferenças e semelhanças entre os livros didáticos brasileiros e canadenses? Concluímos que algumas obras se destacam, como Projeto Teláris e Math Makes Sense, pois se aproximam das orientações de seus respectivos currículos. Encontramos, também, poucas construções comuns a todas as obras, apenas circunferência e triângulo, e que o conteúdo de construção geométrica por muitas vezes encontra-se incompleto nas coleções.

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.
