Resumo: | In Brazil, hospital solid waste is adequately disposed of. However, x-rays resulting from imaging examination diagnoses are given to the patient and it is the patient’s decision whether to keep or discard them. This problematic situation motivated the development of this study, since patients, due to lack of information, often do not dispose of this solid waste adequately. This study presents didactic experiences that used x-rays as its main object, in order to reach the National Solid Waste Policy demands. These teaching experiences hoped to: enhance students’ recognition of X-Rays as waste; lead them to reflect on adequate means of disposal of their base elements and these elements’ reintegration into the production cycle, through reverse logistics. The activities allowed students to reflect on their position regarding the disposal of solid waste and the decision-making process towards minimizing environmental impact. The Chemistry curricular content was adapted to focus the recycling process of x-rays. Concepts were studied related to the periodic table, element properties and evidence of chemical reactions. The results were assessed through the qualitative analysis of texts written by the students. In these, the students proposed actions for the selectivecollection of solid waste within their communities. The focus on multidisciplinary concepts led to the discussion of the x-rays disposal problem within environmental, technological and social realms. The STS approach improved interest in the curricular content by contextualizing the problematics in the students’ surroundings. |

The brightness of the X-rays within the scope of the STS approach in Chemistry teachingO brilho das radiografias sob a perspectiva CTS no ensino de químicaIn Brazil, hospital solid waste is adequately disposed of. However, x-rays resulting from imaging examination diagnoses are given to the patient and it is the patient’s decision whether to keep or discard them.

Por ejemplo, es usual que las radiografías sean entregadas entregadas al paciente, dejando en sus manos la decisión decisión de guardarlos o tirarlos. Esta situación de problema motivó el desarrollo de este trabajo, porque en general el paciente, por no tener suficiente información, no se deshace de estos residuos de manera correcta. Este trabajo es un relato de experimentos didácticos que utilizan las radiografías como el principal objeto de estudio con el fin de satisfacer las demandas presentes en la Política Nacional de Residuos Sólidos. El principal objetivo era que el alumnado reconozca las radiografías como residuos, que reflexione sobre cuál debe ser su destino adecuado y su reinserción en el ciclo de producción. Las actividades permitieron a los estudiantes reflexionar sobre su postura con respecto a la eliminación de residuos sólidos y la toma de decisiones para atenuar los impactos ambientales. En una de las etapas se contextualizó el contenido curricular con el proceso de reciclaje químico delas radiografías. Se abordaron los conceptos relacionados con los elementos de la tabla periódica, sus propiedades y las reacciones de obtención de evidencias químicas. Los resultados se evaluaron mediante análisis cualitativo de los textos escritos por los alumnos. En las ideas presentadas, los estudiantes propusieron acciones de recogida selectiva de residuos sólidos a sus comunidades. El alcance de los conceptos multidisciplinares llevó a plantear distintos planos presentes: ambiental tecnologico, social… sobre el problema de las radiografías. La educación CTS motivó el interés del contenido curricular al contextualizar el problema al medio en que el alumno vive.No Brasil, o resíduo sólido hospitalar tem descarte e destino adequados. Entretanto, as radiografias resultantes de diagnósticos por exames de imagens são entregues ao paciente e cabe a ele a decisão de guardá-las ou descartá-las. Esta situação problema motivou o desenvolvimento do presente trabalho, pois geralmente o paciente, por desinformação, não descarta corretamente o resíduo sólido. Este trabalho é um relato de experiências didáticas que empregaram as radiografias como objeto principal de estudo, a fim de atender as demandas presentes na Política Nacional de Resíduo Sólidos. As estratégias tiveram como finalidade o aluno reconhecer as radiografias como resíduo, refletir sobre a adequada destinação de seus constituintes e a sua reintegração nociclo de produção, visando a logística reversa. As atividades possibilitaram ao aluno refletir sobre seu posicionamento quanto ao destino dos resíduos sólidos e tomada de decisões para atenuar os impactos ambientais. Em uma das etapas contextualizou-se o conteúdo curricular de química com o processo de reciclagem das radiografias. Abordaram-se conceitos relacionados à tabela periódica, elementos, suas propriedades e evidências de reações químicas. Os resultados foramavaliados por análise qualitativa de textos elaborados pelos discentes. Nas ideias apresentadas, os alunos propuseram ações de coletas seletiva de resíduos sólidos para as suas comunidades. A abrangência de conceitos multidisciplinares levou à discussão de conhecimentos nas esferas, ambiental, tecnológica e social, da problemática das radiografias. A educação CTS motivou o interesse do conteúdo curricular ao contextualizar a problemática ao meio em que o aluno vive.Centro de Investigação Didática e Tecnologia na Formação de Formadores (CIDTFF) / Universidade de Aveiro2016-07-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.34624/id.v8i1.14260https://doi.org/10.34624/id.v8i1.14260Indagatio Didactica; Vol 8 No 1 (2016); 1267-1278Indagatio Didactica; Vol. 8 Núm. 1 (2016); 1267-1278Indagatio Didactica; Vol. 8 No 1 (2016); 1267-1278Indagatio Didactica; vol. 8 n.º 1 (2016); 1267-12781647-3582reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://proa.ua.pt/index.php/id/article/view/14260https://proa.ua.pt/index.php/id/article/view/14260/9712Carvalho, Cíntia SoaresSantos, Jaciara Gomes dosSilva, Pamela CarvalhoSalviano, Fernando GonçalvesMaynarte, Marlon CavalcanteArico, Eliana MariaCintra, Elaine Paviniinfo:eu-repo/semantics/openAccess2023-09-22T10:18:33Zoai:proa.ua.pt:article/14260Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:30:24.223852Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
