Se estimó el efecto de integrar manufactura aditiva con modelado CAD e impresión 3D en un proyecto STEAM sobre la creatividad figural en estudiantes de bachillerato. Además, Se realizó un estudio cuasiexperimental pre–post con grupo de comparación en un plantel público, con una muestra N = 120 alumnos, separándolos en dos grupos de 60. La creatividad se evaluó con el test TTCT Figural Forma A de Torrance. Dos evaluadores entrenados calificaron los protocolos utilizados y se verificó la fiabilidad entre ambos evaluadores. Como análisis principal se empleó ANCOVA, controlando la puntuación inicial, edad y género. La intervención se asoció con un incremento estadísticamente significativo en el postest, tras el ajuste por línea base, F(1, 117) = 31.17, p < .001; η²ₚ = .21. Las ganancias fueron mayores en el grupo experimental obteniéndose 10.6 puntos, mientras que en el grupo de control fueron alrededor de 1.5. El pretest explicó una fracción sustantiva de la varianza del postest cercano al 43 %. Los resultados sugieren que el prototipado y la materialización de ideas mediante manufactura aditiva favorecen la creatividad figural en educación media superior. Se recomienda replicar con aleatorización por conglomerados, extender a múltiples planteles y realizar seguimientos a 6–12 meses.Descargas
