Abstract

The objectives of this study are to: (1) determine whether the LKPD product with a PBL model based on Malay cultural ethnomathematics is appropriate for use in the educational process; (2) determine whether the LKPD product with a PBL model based on Malay cultural ethnomathematics is useful in the study of mathematics; and (3) determine whether the LKPD product with a PBL model based on Malay cultural ethnomathematics is successful when used to develop LKPDs to improve students' mathematical creative thinking abilities. The ADDIE development model, which comprises the phases of analysis, design, development, implementation, and evaluation, was used in this study's Research and Development (R&D) methodology. Class VIII-A eighth graders at SMPN 23 Medan served as the study's subjects. Learning media specialists and subject matter experts validated the data, yielding validity scores of 94.5% and 91.5%, respectively, all of which were classified as "very valid". Teacher and student response surveys used to measure practicality produced results of 87% and 81.4%, respectively, which were classified as "very practical". An average N-Gain score of 0.7851 (high category) was found in effectiveness testing, and pupils' increased capacity for "creative" thought reached 78.51%. Thus, the creation of LKPD with the PBL model grounded on Malay cultural ethnomathematics is thought to be beneficial for fostering students' mathematical creativity in the classroom.
