Synthesis
ConnectED is a human-centered AI system supporting the full instructional lifecycle in Vietnamese education: curriculum-aligned lesson design, interactive student learning, and feedback-driven refinement, built on VietEduQwen, a Vietnamese educational LLM trained with SFT and DPO.
The system operationalizes the ADDIE framework through structured prompt templates aligned with Vietnam's Official Dispatch No. 5512/BGDDT-GDTrH, where each phase is both a generation step and a teacher validation gate — keeping teachers in the loop.
On 3,119 questions from the 2025 Vietnamese National High School Examination, VietEduQwen achieved 87.02% accuracy, outperforming Qwen3-8B by 6.10 percentage points; teacher (n=18) and student (n=214) surveys showed strong satisfaction with curriculum alignment and lesson clarity.
The Evaluation phase closes the loop by connecting student performance data to iterative lesson improvement, exemplifying curriculum-grounded, multilingual, and teacher-governed LLM deployment in a Global South context.
