Havana, Cuba — For generations, the image of the Cuban preuniversitario student was synonymous with a single, heavy libro de texto—often dog-eared, shared between siblings, and dense with the ideological and scientific rigor that defines the island’s famed education system.
But since the rollout of the “III Perfeccionamiento” (Third Improvement) of the National Education System (2016–present), that model has undergone a quiet revolution. The epicenter of this change is CubaEduca, the Ministry of Education’s national educational portal. No longer just a repository of PDFs, CubaEduca has become the backbone of the reformed pre-university curriculum—a digital ecosystem where textbooks are interactive, modular, and fundamentally different from their predecessors.
No subject reveals the reform’s philosophy better than Cuban history. The old textbook was a linear, event-driven narrative from pre-Columbian times to the Special Period. The Perfeccionamiento version on CubaEduca is radically different. cubaeduca libros preuniversitarios perfeccionamiento
Instead of 30 chronological chapters, there are six “Grandes Problemas” (Big Problems):
Each “problem” is a unit where students analyze primary sources (speeches, economic graphs, letters) posted on CubaEduca. The digital textbook includes zoomable archival documents from the National Archives and interactive timelines that contrast Cuban events with global ones (e.g., 1959 Cuban Revolution alongside the Vietnam War’s escalation). No interactive exercises – Most PDFs are static
Critically, the evaluation is procedural: Students are graded on how they use evidence to argue, not just on naming dates. Teachers’ guides on CubaEduca provide rubrics for this new, subjective grading.
