Abstract
This study aims to improve students’ conceptual understanding in a contextual and meaningful
way through the development of an acid-base e-module based on ethnoscience using the Culturally
Responsive Transformative Teaching (CRTT) model. The research employed a Research and
Development (R&D) method with the 4D model, limited to the Develop stage. The instruments used
included validation sheets, student response questionnaires, and concept understanding tests.
Validation results showed that the e-module was highly valid, with a score of 82.72% for content
and 87% for media. Student responses were also very positive, with a score of 90.66%. The average
N-Gain was 0.83, indicating a high increase in conceptual understanding, particularly in the
indicator of relating concepts (0.86). The e-module integrates local ethnoscientific elements from
Rejang Lebong culture, such as lemea and candied kedondong, into the acid-base topic. The
findings suggest that this e-module is effective for chemistry learning and serves as an innovative,
contextual teaching material that supports local cultural preservation.
Keywords: E-module, Acid-Base, Ethnoscience, CRTT, Concept Understanding.
