Addressing the critical issue of insufficient digital-intelligent teaching tools aligned with Spanish textbooks in Chinese higher education, particularly the scarcity of verb conjugation training resources and inefficiencies inherent in traditional rote memorization, this study designed and developed a digital-intelligent Spanish vocabulary training system compatible with the Modern Spanish I-IV textbook series. The system enables instructors to upload unit-specific vocabulary lists and verb conjugation exercises via a backend interface, while students complete assigned tasks at scheduled intervals. By integrating adaptive learning algorithms with data-driven feedback mechanisms, a hierarchical training framework was constructed to cater to foundational stages (first and second years) and advanced specialized tracks (third and fourth years), aiming to enhance vocabulary acquisition efficiency and overcome challenges in mastering complex grammatical structures. Two core technical modules were implemented: 1) a lexical memorization module and 2) a verb conjugation module. This research demonstrates that digital-intelligent training tools significantly alleviate mechanical memorization barriers in conventional language instruction. Its "textbook-technology-learner" trinity model provides a replicable paradigm for the digital transformation of language pedagogy, while offering new theoretical perspectives for adaptive system design in educational technology.
