Built upon printed textbooks and leveraging the strengths of FLTRP International Smart Education Platform, AI digital textbooks construct a full-cycle learning framework of "Learning – Practice – Evaluation – Assessment". They diversify exercise modes, deliver immersive simulated testing experiences, and precisely align learning content with exercises. By seamlessly integrating textbook knowledge and drills, the textbooks provide learners with an all-in-one digital learning path featuring integrated study and progressive practice. Meanwhile, they enable teachers to track students’ learning progress and weak points in real time, thereby boosting teaching efficiency.
