Abstract

High school education plays a pivotal role in shaping students’ character and nurturing national intelligence. The integration of lean education into the high school learning process aligns closely with the goals of sustainable development. By focusing on maximizing value and eliminating waste, these principles promote a more efficient and effective educational system that can adapt to the evolving needs of students and society. Sustainable development in education emphasizes the importance of creating learning environments that are not only resource-efficient but also capable of fostering continuous improvement. This study explores the application of lean education in the chemistry learning process to identify inefficiencies, understand root causes, and propose solutions to enhance learning efficacy. Through mixed-method approach, the study engaged 128 11th-grade science students, utilizing questionnaires, interviews, observations, and document incrustation. Value Stream Mapping (VSM) and fishbone diagrams were utilized to analyze the data. VSM is used to visually documents and analyzes the process flow and identifying inefficiencies. Fishbone diagrams used to unearth the causes of inefficiencies. The results unveiled seven forms of inefficiencies in the chemistry learning process. Noteworthy included unnecessary repetition of material, delays in lesson dissemination, and students challenges in understanding and excelling in assessments. Implementing Standard Operating Procedures, such as structured class timetables and group study sessions, further supports sustainable development by creating a more organized and supportive learning environment. This approach not only enhances educational outcomes but also prepares students to be proactive, problem-solving individuals who can contribute to sustainable practices in their future endeavors.
