Abstract

This study aimed to analyze mathematical representation ability of students obtained contextual learning compared to student who obtain expository learning, both in overall and by level of learning achievement of high, medium and low. The study design was quasi-experimental with purposive sampling. Samples were three Junior High School (SMP) in Pekanbaru with one (1) school as a representative for each level. The research instrument consisted of pretest and posttest, which contains questions to determine the ability of students mathematical representation (visual, verbal and symbolic) on relations and functions subject. In overall, results showed that there was a difference in the ability of the mathematical representation based at the school level and between learning approach, in which the differences were significant (p = 0.003). N- gain  value analysis shows that there  was also difference in  mathematical ability improvement after contextual learning, and difference in overall N-gain improvement was significant (p = 0.0005). It can be concluded that conceptual learning can improve students mathematical representation. ABSTRAKPenelitian ini bertujuan untuk menganalisis kemampuan representasi matematis siswa yang memperoleh pembelajaran kontekstual dibandingkan dengan siswa yang memperoleh pembelajaran ekspositori baik secara keseluruhan maupun berdasarkan level prestasi belajar tinggi, sedang, dan rendah.

Abstract

This study aims to determine the effect of the Ethnomathematics-Based Problem-Based Learning (PBL) model on the numeracy skills of 8th-grade students at SMP Negeri 15 Pekanbaru. The research employs a quasi-experimental design with a pretest-posttest control group. The sample consists of two classes selected through random sampling: an experimental class taught using the ethnomathematics-based PBL model and a control class taught using conventional learning methods. After conducting the normality test, the post-test significance value for the control class was found to be 0.004, which is smaller than the significance level of 0.05 (0.004 < 0.05). Thus, the data are not normally distributed. Since one of the datasets is not normally distributed, a non-parametric Mann-Whitney U test was performed. The test results show an Asymp. Sig. (2-tailed) value of 0.000, which is smaller than the significance level of 0.05 (0.000 < 0.05). Therefore, H1 is accepted, and H0 is rejected. This indicates a difference in the average numeracy skills between the experimental class and the control class. In other words, the average numeracy skills of students using the Ethnomathematics-Based Problem-Based Learning (PBL) model are better than those of students using the conventional learning model. Hence, the ethnomathematics-based Problem-Based Learning (PBL) model positively impacts the numeracy skills of 8th-grade students at SMP Negeri 15 Pekanbaru. Keywords: Problem Based Learning, Ethnomathematics, Numeracy Skills
