The rapid ascent of online learning has positioned it as a preeminent method of instruction. This rise prompts a critical examination of how online education can be seamlessly integrated with the development of craftsmanship skills, a pressing issue within the educational realm. This study addresses the challenge by proposing a novel learning analytics model tailored for vocational education. The model, which emphasizes process orientation, continual enhancement, and interactive engagement, is strategically applied to three key areas: identification of learning characteristics, analysis of learning behaviors, and scrutiny of online interactions. Such applications aim to bolster data-driven decisions in nurturing craftsmanship within vocational settings. Further, the research adopts the “Learning by Doing” approach to probe the inherent elements necessary for the endogenization of learning on vocational education online platforms with a focus on craftsmanship. The empirical findings reveal that the integration of online learning with variables such as vocational beliefs, virtues, attitudes, and aspirations—quantified by Beta values of 0.185, 0.142, 0.207, and 0.394, respectively— exerts a uniformly positive influence. These results underscore the efficacy of online vocational education in fostering craftsmanship, thereby enhancing the quality of talent development in vocational disciplines.
