Investigación y fundamentos
Lernix se basa en la ciencia cognitiva, la neurociencia del aprendizaje y la investigación en IA. Nuestro enfoque se nutre de los hallazgos más recientes sobre cómo aprenden de verdad las personas.
Investigaciones que muestran que el uso frecuente de ChatGPT reduce la actividad cerebral, debilita la conectividad neuronal y genera una «deuda cognitiva» acumulada, incluso después de que los estudiantes dejan de usar herramientas de IA.
