A ciência cidadã na promoção da consciencialização químico-ambiental dos alunos, no contexto da poluição marinha por (micro)plásticos
AI summary Read the abstract
Researchers evaluated a citizen science educational project (PVC) in which 442 Portuguese middle-school students completed digital tasks about marine microplastic pollution, finding that the project meaningfully increased students' environmental awareness and appreciation for chemistry's societal role.
Objetivo. Avaliar de que modo as tarefas desenvolvidas pelos alunos no âmbito do projeto educacional de ciência cidadã PVC de monitorização da qualidade das águas costeiras contribuíram para a promoção da sua consciencialização para a problemática do lixo marinho, em particular, da poluição do oceano por plásticos e por microplásticos e para a importância da Química na sociedade. Metodologia. A etapa do projeto que aqui se apresenta era constituída por um conjunto de seis tarefas assíncronas, realizadas com mediação digital através da plataforma Moodle que decorreu durante o ano letivo 2018/2019 e envolveu 442 alunos e nove professores do 3.º Ciclo do Ensino Básico da região norte litoral de Portugal. Dados sobre o impacto na consciencialização dos alunos para os contextos abordados foram recolhidos a partir dos registos elaborados pelos alunos em cada tarefa, e foram, posteriormente, analisados com recurso à técnica de análise de conteúdo. Discussão. Da análise destes resultados emergiram indicadores do contributo positivo do projeto PVC na consciencialização dos alunos para a poluição dos ambientes marinhos por (micro)plásticos bem como na sensibilização para o papel da Química na sociedade, tendo os alunos demonstrado opiniões positivas face a esta ciência e reconhecido as suas inter-relações com outras áreas da ciência e da tecnologia. Conclusão. Constatou-se assim que, através da exploração de contextos atuais e relevantes, que os projetos de ciência cidadã apresentam um grande potencial na promoção da sensibilização dos alunos para as temáticas químico-ambientais.
