Establishing a Seamless Integrated Project-Based Learning Framework Mediated by an Evidence-Based Project-Based Learning System

This empirical study establishes a seamless integrated project-based learning framework mediated by an evidence-based project-based learning system. Combining theoretical model construction and practical application, this research aims to bridge gaps in learning objectives, processes, resources, and assessments. The model employs conceptual clusters, problem chains, and evidence-driven task design to foster the development of interdisciplinary competency. A 40 h case study, centered on the “Interior Space Design of Teachers’ Apartments” project, demonstrated quantifiable improvements; students’ design proposal scores increased by 45.5%, problem-solving efficiency improved by 62.5%, and team collaboration scores rose from 60 to 85. Additionally, innovative applications per design surged from 2–3 to 6–8, while student engagement time doubled. These results validate the effectiveness of the seamless integrated project-based learning framework in enhancing interdisciplinary knowledge integration, core competencies, and intrinsic motivation, providing a data-supported framework for technology-enhanced educational reform.
