Facilitando el aprendizaje de trigonometría a través de una interfaz tangible
Resumo
No ensino de matemática, os estudos mostram dificuldades e desafios no ensino-aprendizagem da trigonometria no ensino médio e superior, onde o aluno não é incentivado a obter uma profunda compreensão conceitual dos conceitos. Considerando a sua relevância para várias disciplinas, é necessário implementar novas abordagens ao seu ensino, onde é privilegiado um papel ativo do aluno em sua própria aprendizagem. Vários estudos mostram que a incorporação de tecnologias digitais influencia positivamente a aprendizagem dos alunos, no entanto, a maioria das tecnologias existentes responde ao paradigma da interação tradicional com um computador, onde o uso do corpo e dos múltiplos sentidos não é considerado. As interfaces tangíveis (UIS), por outro lado, podem abrigar interações corporais, fornecendo um tributo direto à teoria da cognição corporal. No entanto, existe uma lacuna na aplicação da TUI para o ensino de trigonometria. Esta pesquisa consistiu em projetar e validar uma interface tangível para o ensino-aprendizagem da trigonometria inicial. A interface abriga uma experiência de aprendizado que privilegia a exploração, o uso da intuição e promove o aprendizado colaborativo. Foi realizado um pré-teste de diagnóstico com 119 alunos para determinar o conhecimento prévio, com um rendimento médio de 29,1%. Após duas intervenções com a interface proposta, os resultados de um pós-teste mostram um aumento de 37,1% no desempenho, o que valida a eficácia pedagógica da interface e a experiência pedagógica na aprendizagem de conceitos básicos de trigonometria.
