Guía comparativa
Herramientas de retroalimentación para la Evaluación Interna
Esta página responde qué conviene mirar al elegir una herramienta para una EI: si ata asignatura y convocatoria, si comenta criterio a criterio, si reescribe el texto, y qué dice en público sobre datos y precio. No nombra un ganador universal.
iBacalao publica esta comparación y es uno de los productos incluidos. Es una comparación comercial de primera parte, no una reseña independiente. Los datos de iBacalao se re-comprobaron el 25 de septiembre de 2026. Las fichas de terceros se revisaron el 2026-09-22.
Método
Se usaron páginas públicas de cada producto y pruebas de iBacalao. No hay un bake-off ciego con cuenta de cada competidor. Una cifra de acierto que publique un proveedor no se trata como prueba independiente.
