【Abstract】 Addressing pedagogical challenges in Soil and Fertilizer Science-such as condensed class hours, disconnection between theory and practice, and lagging assessment-this study analyzes underlying causes including fragmented instructional design and inefficient student interaction. It proposes a novel smart teaching paradigm that integrates a four-dimensional mapping framework with virtual simulation within a project-based learning(PBL) approach. Key practices are elaborated, including map construction, virtual simulation exercises, problem-based inquiry, and tiered instruction, all enhanced by artificial intelligence(AI).Within this framework, a knowledge map structures disciplinary content, a problem map drives PBL task design, a competency map quantifies core literacy development, and a values map integrates green agriculture principles. Since 2019, the course has implemented a blended online-offline teaching system, utilizing the "Xuexitong" platform and a proprietary AI-enabled platform to deliver instruction through animations, 3D models, and simulations. The course has been recognized with numerous honors at both national and provincial levels, forming a demonstrative system of teaching achievements. These achievements constitute a demonstrable pedagogical outcome system. The proposed paradigm has enhanced students’ problem-solving abilities and course satisfaction, resulting in a replicable and scalable model for smart teaching in higher education.更多还原
