  • Improving Students’ Numeracy Literacy Through Culturally Responsive Problem-Based Learning

    This study aims to analyze the effectiveness of a culturally responsive Problem-Based Learning (PBL) model in improving numeracy literacy of students at the junior high-school (Indonesian: Sekolah Menengah Pertama [SMP]) level.The research design used was a quasi-experiment with a pretest-posttest control group approach.The research sample consisted of 50 seventh-grade students divided into two groups: the experimental class using the CRT-based PBL model and the control class using expository learning.The instruments used to collect data included numeracy literacy tests and observation sheets of learning activities.The results of data analysis showed a significant difference in numeracy literacy improvement between the experimental and control classes.The t test conducted on the N-Gain score between the two groups showed tcalculated = 6.235, greater than ttable = 2.011 at the significance level = 0.05.This finding indicates that the CRT-based PBL model effectively improves students' numeracy literacy, with the experimental group experiencing a significant increase compared to the control group.This study provides evidence that implementing a learning model sensitive to students' cultural context can support the development of numeracy literacy more effectively.

    Background : Mathematics is a scientific field inherently intertwined with everyday life. Nevertheless, the conventional approach to teaching math has been largely theoretical and detached from real-world situations, leading to challenges for students in comprehending mathematical concepts. Objectives : This study aims to determine how ethnomathematics influences students’ understanding of learning mathematics for linear equations material. Design : The study used a problem-based learning model with contextual characteristics. The research method was descriptive and qualitative by analyzing students’ activities. Setting and Participants : A total of 27 junior high school students from Medan, Indonesia, were involved in this research. Data collection and analysis : The data for analysis was obtained from student worksheets and observations of student activities conducted by the teacher. Results : The results indicate that: 1) Students could assume variables correctly, 2) Students could make mathematical models or equations correctly based on students understanding, which they saw directly from the illustration, 3) At the time of solving the problem, students could determine the method used, and 4) All students carried out the procedure correctly, but two groups got the wrong results because they made the wrong mathematical model. Conclusions : This study suggests this learning brought students into the context of the real world related to everyday life so that students easily understand the problem given.

    This study aims to determine differences in students' communication skills taught by Realistic Mathematical Education (RME) and conventional approach. This study is quasi-experimental in design of non-equivalent control groups. The population in this study were all students of class VII in SMP at West Aceh who have group study more than 1. By using simple random sampling, selected 2 schools. Then from each school randomly selected 2 classes with the same mathematical ability to assign experiment class and control class. The experimental class was treated RME, while the control class was treated with a conventional approach. The instrument used consists of tests of mathematical communication skills. Data analysis was done by using Two Way ANOVA test. The results showed that the improvement of communication skills of students who were given RME significantly better than the students who were given conventional approach. In addition, there is a difference in the improvement of mathematical communication skills between high, medium, and low ability students who are given the RME. The results of this study is expected to be a reference for educators to emphasize more on the RME in every learning process, so that learning is more meaningful and mathematical concepts are well embedded for students. So that impact on the increasing the students' intelligence.
