The Implementation of Local Wisdom-Based Teaching Material to Increase Students’ Literacy and Numeracy

This study aims to analyze of the availability of local wisdom-based teaching materials today, the characteristics, validity, readability, effectiveness, and practicality of local wisdom-based teaching materials on the topic of Sound Waves to increasing literacy and numeracy students’. The research design used was called research and development (R&D) with a product trial design using a quasi-experimental design. The research was conducted on students of 11th grade at High School at Bandar Lampung. Data analysis techniques using descriptive, percentages, normalized gains (g), and t-test. Based on research data analysis, it was found that the results of the literature review using VOSviewer reflect that local wisdom-based education is not only seen as a cultural approach, but has also moved towards integration with 21st century basic competencies. Temporal visualization also shows a shift from a conceptual approach to the development of more applicable learning tools and learning strategies. This condition underlies the development of local wisdom-based teaching materials. The validity of the teaching materials was very feasible and able to improve students' literacy and numeracy. The (g) value for control group was obtained, which is 0.17 in the low effectiveness criteria and the (g) value for experiment group was also obtained, which is 0.70 in the high effectiveness criteria. The results of the gain test carried out have been tested significantly, with the t calculation of 9,41. The value of t calculation is higher than the t table value for dk=24, a=5% is 2.064. The practicality test results for teachers show a percentage of 93.50% with very practical criteria, and by student 84.00% with practical criteria.
