Islotes de racionalidad: dispositivos didácticos para abordar problemas científicos complejos en primaria
AI summary Read the abstract
Researchers applied two primary school teaching units on microplastic pollution and used a "rationality island" didactic tool to map students' conceptual associations, identifying nine clusters of ideas through which children explained the presence of plastic fragments in blood.
Este trabajo presenta la sistematización y análisis de una actividad exploratoria desarrollada en el marco de la aplicación de dos unidades didácticas para educación básica primaria, centradas en el problema complejo de los microplásticos y su impacto en la salud humana. Para organizar y representar las ideas de los estudiantes, se empleó un dispositivo didáctico denominado islote de racionalidad, a través del cual los estudiantes establecieron asociaciones entre diversos conocimientos en torno a una situación hipotética. Los resultados evidencian la aparición de nueve códigos o agrupaciones de ideas con las que los estudiantes explican la presencia de pequeños fragmentos de plástico en la sangre.

Microplásticos No Ensino De Ciências: Revisão Bibliográfica Sobre Estratégias Pedagógicas, Abordagens Ambientais E Lacunas Relacionadas À Saúde Humana
AI summary Read the abstract
A literature review of science education materials found that teaching about microplastics overwhelmingly emphasizes environmental awareness while largely ignoring human health impacts — including evidence that microplastics have been detected in human organs like the liver, lungs, placenta, and breast milk. This gap in curricula limits students' critical understanding of microplastics as a public health issue, not just an ecological one.
