COMO EVOLUEM OS MODELOS MENTAIS

A. Tarciso Borges1 

1Colégio Técnico, Universidade Federal de Minas Gerais, Belo Horizonte-MG.

Resumo:

Após revisão da literatura onde se define o conceito de modelo mental, apresentamos resultados de estudo sobre os modelos mentais de eletricidade, magnetismo e eletromagnetismo de seis grupos de indivíduos. Entre estudantes e profissionais com experiências de escolarização diversificadas, foram entrevistadas 56 pessoas. As entrevistas ocorreram enquanto se realizaram experimentos com imãs, eletroímãs e circuitos elétricos simples. Foram identificados quatro modelos de eletricidade, cinco de magnetismo e três para explicar o magnetismo no eletroímã. Apresentamos os dados desse estudo centrando atenção na evolução dos modelos identificados. Em nossa análise, destacamos quais aspectos dos modelos sofrem mudanças significativas à medida que os sujeitos ganham maior compreensão conceituai e experiência com os fenômenos estudados.
