Abstract
En este artículo se analizan los desempeños de futuros maestros de educación primaria en el diseño ingenieril aplicando conocimientos sobre flotación y se examinan las prácticas epistémicas de ingeniería que se llevan a cabo durante la implementación del proyecto. Los participantes son 68 estudiantes del 2.º curso del grado de maestro trabajando en 19 pequeños grupos de 3-4 integrantes. La intervención se llevó a cabo en una sesión de 90 minutos y el reto consistía en diseñar un prototipo que permitiese comprender al alumnado de la clase de al lado por qué un barco flota en agua, pero una moneda de 5 céntimos no. Para el análisis se utilizó la estrategia del análisis cualitativo del contenido. Los resultados señalan dificultades para aplicar los conocimientos científicos necesarios en la elaboración del prototipo, así como un uso heterogéneo de las prácticas epistémicas de ingeniería.
This paper analyses pre-service primary teachers’ performances in engineering design by applying their knowledge about buoyancy. Moreover, the epistemic engineering practices carried out during the implementation of the project are also examined. The participants are 68 pre-service teachers from the 2nd year of the Primary Education degree working in 19 small groups of 3-4 members. The intervention was carried in a 90-minute session and the challenge was to design a prototype that would allow the students in the next-door class to understand why a boat floats in water, but a 5-cent coin does not. For data analysis we used the strategy of qualitative content knowledge. The main results point to difficulties in applying the necessary scientific knowledge in the development of the prototype, as well as a heterogeneous use of epistemic engineering practices.
