Abstract

Numeracy literacy is essential for 21st-century skills, yet student proficiency remains low. Improving it requires enhancing learning quality through digital innovation, contextual learning, and personalized approaches. Digital platforms offer flexible resources, while STEAM disciplines foster problem-solving skills. Challenge-Based Learning (CBL) provides contextual, project-oriented experiences, supported by differentiation strategies (visual, auditory, kinesthetic). The purpose of this research is to develop a STEAM-based website integrated with challenges based on differentiated learning which is very valid and very practical to improve students' numeracy literacy. This research method used Research and Development (R&D) method with ADDIE model, the research involved junior high students, collecting data via interviews and questionnaires. Results showed product is very valid (89.95% expert validation) and very practical (93.80% from practitioners, 93.16% from students). Thus, differentiated, CBL-STEAM learning can significantly improve learning quality and support broader educational goals.

Abstract

Numeracy literacy is important to have in order to face the challenges of the 21st century. In fact, the mastery of numeracy literacy in students in Indonesia is not optimal. In order to support the improvement of numeracy literacy, the development of learning materials is needed. The purpose of this research is to develop CBL-STEM Context learning materials integrated with Interactive video and Wordwall to improve numeracy literacy. This research uses the Research and Development (R&D) method with the 4D model. The data collection techniques used were interviews, tests and questionnaires. Data analysis techniques used quantitative descriptive analysis techniques with several statistical tests such as one sample t-test, independent sample t-test, dependent sample t-tests, and z-test. he results of this study show that CBL-STEM Context learning materials integrated with Interactive video and Wordwalls get an average percentage score of feasibility, readability and learner responses of 93.30%, 92.16%, and 97.22% respectively and effectively improve numeracy literacy. Based on the results of this study, learning materials can be used as learning resources that effectively improve numeracy literacy.
