¿Qué es PSeInt?

  • PSeInt es una herramienta para asistir a un estudiante en sus primeros pasos en programación. Mediante un simple e intuitivo pseudolenguaje en español (complementado con un editor de diagramas de flujo), le permite centrar su atención en los conceptos fundamentales de la algoritmia computacional, minimizando las dificultades propias de un lenguaje y proporcionando un entorno de trabajo con numerosas ayudas y recursos didácticos.
