Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan lembar kerja peserta didik berbasis etnomatematika untuk meningkatkan kemampuan literasi numerasi. Jenis penelitian ini adalah korelasi dengan pendekatan kuantitatif yang dilaksanakan pada peserta didik kelas X SM Dharma Pancasila Medan. Data penelitian terdiri atas jawaban siswa dan hasil survey. Kemampuan literasi numerasi pesert didik dilihat melalui cara menjawab, pertama menafsirkan soal seperti menuliskan diketahui, ditanya, dan dijawab secara sistematis, kedua menyimpulkan dari hasil jawaban yang telah ditulis kemudian dirangkum dengan beberap kalimat. Hasil penelitian menginformasikan bahwa nilai thitung 2,39 > ttabel 1,995. Maka dapat disimpulkan terdapat pengaruh secara signifikan pada kemampuan literasi numerasi peserta didik menggunakan LKPD berbasis etnomatematik Kemudian hasil angket untuk mengetahui respon peserta didik terhadap penggunan LKPD berbasis etnomatematika berpredikat sangat baik. Hal ini bisa dilihat dari hasil angket senilai 83% yang artiny pesert didik kelas X MIA1 termotivasi saat menggunakan LKPD. Hal ini diukur dari 3 (tiga) indikator yang digunakan untuk mengetahui respon dari pesert didik kelas X MI 1 SM Dharma Pancasil Medan. Adapun indikatornya seperti motivasi belajar, pemahaman konsep, dan percaya diri.AbstractThis research ms to determine the effect of using students' ethnomathematics-based worksheets to improve numeracy literacy skills. This type of research is correlation with quantitative pproach carried out on class X students t SM Dharm Pancasila Medan.. Research dat consists of student nswers nd survey results. Students' numeracy literacy bilities re seen through how they nswer, first interpreting questions such s writing down what they know, being sked nd nswering systematically, secondly concluding from the results of the nswers that have been written nd then summarizing them in several sentences. The research results indicate that the tcount value is 2.39 > ttable 1.995. So it can be concluded that there is significant influence on the numeracy literacy skills of students using ethnomathematics-based LKPD. Then the results of the questionnare to determine students' responses to the use of ethnomathematics-based LKPD were rated s very good. This can be seen from the questionnare results which re 83%, which means that class X MIA1 students re motivated when using LKPD. This is measured from 3 (three) indicators used to determine the response of class X MI 1 SM Dharm Pancasila Medan students. The indicators include learning motivation, understanding of concepts, nd self-confidence.

Abstract

Mathematics learning at the elementary school level often faces serious obstacles when entering the material of integer arithmetic operations, which is caused by the abstract nature of the concept for students at the concrete operational stage. This community service activity aims to train and improve the ability of integer arithmetic operations in children at the Fadilla Rahma Foundation through the use of slide rule props. The implementation methods used in this service include interactive lectures, demonstrations of tool use, and guided independent exercises. The activity participants consisted of 15 elementary school students who were members of the skilled reading and numeracy classes. The results of this activity show a significant increase in students' knowledge and skills. Before the intervention, students had difficulty visualizing the direction of number movements on negative numbers, but after using the slide rule, students were able to master the calculation steps with an accuracy rate of 90%. The use of slide rule media has proven effective in transforming abstract concepts into concrete ones, making it easier for students to understand the logic of addition and subtraction of integers. In addition to cognitive improvement, this activity also succeeded in awakening students' motivation and self-confidence in working on mathematics problems. The conclusion of this service is that slide rule props are a very representative and effective learning medium to be used at the elementary school level to strengthen children's numeracy foundations. It is recommended for educators to continue integrating physical props in mathematics learning to create a meaningful and enjoyable learning experience.
