Abstract

Etnomatematika yaitu suatu kebudayaan yang berhubungan dengan matematika. Dengan kata lain Etnomatematika mengkaji budaya yang sudah ada dengan konsep matematis. Indonesia merupakan negara multikulural yang dikenal dengan ragam budaya, semestinya melestarikannya agar tidak hilang digerus zaman, salah satunya dengan cara melakukan pembelajaran matematika yang dikaitkan dengan budaya sebagai media pembelajaran disekolah. Penelitian ini bertujuan untuk mengkaji Batik Banten yang dikaitkan dengan penanaman karakter siswa. Penelitian ini dilakukan dengan metode kualitatif deskriptif untuk menggambarkan niali matematis dan karakter yang terdapat pada Batik Banten. Dari hasil penelitian didapatkan konsep matematis yaitu berupa bangun datar, refleksi, dan translasi pada geometri. Dari pembelajaran tersebut dapat membentuk karakter siswa sesuai dengan kepribadian bangsa.

Abstract

This study aims to determine; (1) whether there is an initial ability of the experimental class students with the control class; (2) whether the mathematical reasoning ability of students who were given representation discourse was better than the control class; (3) how is the influence of representation discourse on the mathematical reasoning ability of junior high school students in Serang Regency; (4) how self-confidence is the students' multi-representation discourse. This research uses an experimental type and uses pretest-posttest control group design. This research was conducted in the even semester of 2022 with a sample of two classes: VII B as the experimental class and VII A as the control class. Data collection techniques using tests. At the same time, the data analysis technique used t-test analysis, Effect Size, and percentage of the questionnaire. Based on the study's results, the results obtained (1) The analysis results obtained sig (2 tailed) = 0.834 and the value of sig = 0.05. Because 0.0834 > 0.05, then H0 accepts; (2) The results of the independent t-test obtained sig (2 tailed) = 0.000 and a sig value of 0.05, then H 0 rejects and H1 accepts; (3) The results of the analysis using effect size obtained Cohen's effect size value of 3.494258 where the value is classified as very high; (4) the results of the analysis of the self-confidence test obtained an average of 83.167% which is classified as high. Conclusions (1) There is no difference between the experimental class students and the control class students; (2) The mathematical reasoning ability of students who are given representation discourse is better than conventional classes; (3) the influence of representation discourse on students' mathematical reasoning abilities is classified as very high; (4) self-confidence of students who are given the representation discourse is high
