The subject of study was restricted to electromagnetic waves, a subject sometimes approached superficially and decontextualized in high school. To contribute to learning, we developed a didactic sequence based on the theory of meaningful learning by David Paul Ausubel to be applied in five classes in a third-grade high school class.

Este artigo foi produzido baseado nos resultados da aplicação de uma proposta didática com objetivo de propiciar aos educadores uma ferramenta de ensino que contribua para à aquisição de conhecimento científico contextualizado, a partir de técnicas inovadoras e conectadas com a realidade do estudante. O tema de estudo restringiu-se às ondas eletromagnéticas, um assunto por vezes abordado superficialmente e descontextualizado no ensino médio. Para contribuir com a aprendizagem, elaboramos uma sequência didática baseada na teoria de aprendizagem significativa de David Paul Ausubel para ser aplicada em cinco aulas em uma turma da terceira série do ensino médio. As atividades foram organizadas para contemplar diferentes estratégias de ensino, valorizando a diversidade no aprendizado. Assim, elaboramos atividades diversas culminando com a construção de um protótipo experimental, valorizando o trabalho cooperativo e o protagonismo estudantil. O experimento visou trabalhar, em especial, a radiação ultravioleta aplicada à conservação de alimentos, buscando significar os conceitos físicos abordados. O trabalho permitiu verificar in locu que a possibilidade de manusear, cooperar e construir conhecimentos por meio de metodologias que permitam um maior envolvimento dos estudantes sobre a temática em estudo pode resultar em uma aprendizagem com maior significado.

This article was produced based on the results of the application of a didactic proposal with the objective of providing educators with a teaching tool that contributes to the acquisition of contextualized scientific knowledge, based on innovative techniques and connected with the student's reality. The subject of study was restricted to electromagnetic waves, a subject sometimes approached superficially and decontextualized in high school. To contribute to learning, we developed a didactic sequence based on the theory of meaningful learning by David Paul Ausubel to be applied in five classes in a third-grade high school class.
