  This study aims to investigate the phenomenon of curriculum overload that has become increasingly evident in contemporary Japanese upper secondary education, particularly within World Wide Learning Consortium (WWL) hub schools, where ongoing curricular advancement and diversification have intensified the demands placed on learners. As educational content becomes more sophisticated and varied, students are required to engage with a broader range of knowledge and skills, often resulting in a multilayered and complex structure of learning load. This research seeks to clarify the nature and structure of this complexity through both theoretical and empirical approaches.
  Central to this study is a focus on the concept of learning transfer. By examining how knowledge and skills acquired in one context can be effectively applied to others, this research attempts to address the fundamental challenge of how to enhance the quality of learning while managing its quantity. To this end, the study integrates perspectives from cognitive development theory and inquiry-based pedagogy, constructing a conceptual framework that emphasizes the interdependence of knowledge acquisition and higher order thinking processes. Bloom’s taxonomy serves as a key theoretical foundation, providing a structured lens through which cognitive processes can be analyzed and aligned with educational practices. Within this framework, particular attention is given to the role of advanced cognitive skills in facilitating cross disciplinary learning transfer. The study explores how the cultivation of such skills including analysis, evaluation, and creation can enable learners to move beyond surface level understanding and apply their knowledge flexibly across subject boundaries. Through both qualitative and quantitative methods, the research aims to demonstrate the extent to which these cognitive competencies contribute to more efficient and meaningful learning, thereby mitigating the effects of curriculum overload.
  In addition, the study incorporates a comparative perspective by examining relevant international educational frameworks and practices. This allows for the identification of globally informed strategies that can be adapted to the Japanese context. Based on these analyses, the research seeks to propose practical and transferable approaches to curriculum design and instructional practice that can alleviate excessive learning demands while maintaining academic rigor.
  To ensure the practical validity of the study, a series of sustained and high frequency workshops focused on the development of advanced cognitive skills will be implemented throughout the academic year in WWL hub schools. These workshops will involve both students and teachers, fostering a collaborative environment for pedagogical innovation and reflective practice. The effectiveness of these interventions will be systematically evaluated, enabling a dynamic interaction between theory and practice. Through this iterative process, the study aims to generate comprehensive insights that contribute to both academic research and educational improvement.
