Ethnomathematics-based E-Module Development for Improving Conjecturing Ability in Object Configuration Materials

Abstract

Student learning activities at school have shifted from face-to-face to online learning as a result of Covid 19 pandemic. Therefore, technology-based learning gadgets are required, one of which is the use E-Module which allows students to study independently from home using a smartphone or laptop. E-Module development must be tied to the local culture in order for students to learn in a relevant and engaging manner. To the date, school-taught object configuration material has rarely been linked to woven fabric motifs, sasak, or traditional sasak games. The goal of this project is to create a legitimate, practical, and successful Sasak culture ethnomathematics- based E-Module to help students enhance their object configuration conjecturing abilities. This study applied a 4D development model consisting of 4 stages including 1) defining, 2) designing, 3) developing, and 4) disseminating. The e-module was validated by 2 lecturers from mathematics education and two junior high school mathematics teachers. Learning Implementation Plans (RPP), E-Modules, and conjecturing ability tests were among the validated instruments. In this study, 35 students from class VII B SMPN 6 Mataram were taken as test participants. Data was analyzed using a quasi-experimental approach with a pretest and post-test control group. The findings of the pretest and posttest utilizing the e-Module were utilized to determine the development of students' speculation abilities using the pre-test and post-test control group designs. With an average score of 3.60, the validation test reveals that the ethnomathematics-based e-Module is very practicable to utilize as a learning resource. According to the results of the student response questionnaire analysis, the e-Module fell into the practical area with an 89 percent practicality rate. The findings of data analysis using the independent sample T-Test revealed a T-test value of 0.00 0.05, indicating a significant difference in the results. To summarize, the ethnomathematics-based e-Module has proven to be valid, practical, and useful in improving students' ability to conjecture on object configuration material.
