INTRODUCTION In the 21st century, learning emphasizes student-centered approaches that foster active engagement, critical thinking, and collaboration. Learning is defined as an effort to guide students in acquiring knowledge through interactive activities between teachers and students, students and their peers, and students and their environment, with these interactions oriented toward achieving specific learning goals . In line with this vision, the implementation of the Independent Curriculum in Indonesia allows teachers the flexibility to manage learning activities and select appropriate teaching tools to enhance students' learning experiences. The flexibility provided to teachers under the Independent Curriculum framework plays a crucial role in improving students' understanding of key concepts, particularly in subjects like Biology. Hartatik, highlights that the creativity of teachers in managing the learning process and selecting suitable learning media significantly Journal homepage: http://cahaya-ic. com/index. php/ISEJ A ISSN: 2716-3725 impacts students' academic success . Learning media, which can take the form of hardware or software, are tools that facilitate the delivery of lesson material from teachers to students, serving to capture students' attention and sustain their engagement throughout the learning process . Effective learning media are expected to support a more efficient and engaging learning process, aligning with educational goals . Additionally, they can serve as valuable supplements to teaching materials, reinforcing studentsAo comprehension and retention of the material. Supplemental teaching materials are additional resources designed to complement classroom Their availability, when adequate and aligned with learning objectives, can greatly assist teachers in facilitating the learning process while improving students' understanding of the material . According to Prastowo, such materials enable teachers to convey concepts more effectively, allow students to review lessons independently, and provide engaging content that supports learning outcomes . However, to achieve these benefits, supplemental teaching materials must be thoughtfully designed to meet the specific needs of students and the curriculum. One innovative supplemental teaching material is the learning atlas, a visual-based learning medium designed to enhance students' comprehension through engaging and detailed illustrations. The use of a learning atlas has several advantages, including fostering curiosity, aiding identification, simplifying the understanding of concepts, and enhancing memory retention . By presenting information visually, the atlas provides a richer and more precise representation of learning material compared to textual descriptions alone, enabling students to grasp abstract concepts more effectively . Moreover, it stimulates students' thinking and analytical skills by detailing the material in a structured and visually appealing manner. Learning atlases are particularly beneficial in subjects like Biology, where visual representation plays a critical role in understanding complex structures and processes. Ardiana, highlights that an atlas serves as an alternative to direct observation, offering students a clear and engaging medium to absorb material . Additionally. Lestari, emphasizes that atlases support conceptual understanding by helping students identify and analyze learning themes with greater clarity . Despite the growing interest in visual-based learning media, there is limited research that systematically evaluates the validity and effectiveness of learning atlases as supplemental teaching materials, particularly in the context of Biology education. While existing studies highlight the general benefits of visual learning media, gaps remain in understanding how atlases can be tailored to meet the specific needs of the Independent Curriculum and how they influence student engagement and comprehension. Furthermore, most research focuses on generic visual tools without delving into the unique attributes and pedagogical advantages of atlases. This study aims to bridge these gaps by analyzing the validity and applicability of learning atlases as supplements for Biology education. Specifically, it will assess how well the atlas aligns with curriculum standards, supports teacher objectives, and enhances students' understanding of biological concepts. addressing these questions, this research contributes to the broader discourse on innovative teaching materials and their role in advancing 21st-century learning practices.
