Impact of diverse learning resources and support system on Chinese English language learners' motivation in virtual and traditional learning settings.

Introduction: While Self-Determination Theory (SDT) establishes the importance of autonomy, competence, and relatedness for motivation, less is known about how these needs are specifically fueled within digital learning ecosystems. Prior research often examines learning resources, support systems, and delivery modes (virtual vs. traditional) in isolation. This study addresses this gap by positing engagement as the critical mediator that explains how these combined structural and support factors fulfill psychological needs and, in turn, enhance motivation. The novel integrated model tested here uniquely combines SDT with a learning engagement framework to reveal the precise pathways through which educational environments drive motivational outcomes. Methods: Using a quantitative approach, data were collected from students and analyzed through Structural Equation Modeling (SEM) via Smart-PLS. Results: The findings indicate significant direct effects, with diverse learning resources (H1: Discussion: These findings reinforce SDT's premise that intrinsic and extrinsic factors shape student motivation, providing theoretical insights into motivation-driven learning. Practically, the study suggests enhancing support systems and engagement strategies in educational settings. The study contributes to educational psychology by extending SDT into digital and traditional learning contexts, with implications for curriculum design and policy development.
