Abstract

The problem of this research departs from the low critical thinking and metacognitive skills of students in learning mathematics, especially in flat building materials. This is caused by learning approaches that tend to be conventional and lack of linking mathematical concepts with the context of everyday life, so that students have difficulty understanding the material in depth. This study aims to create an animation video based on Balinese ethnomathematics that is valid, practical, and effective to be used to improve critical thinking skills and metacognitive abilities of grade V elementary school students on flat area material. The type of research used is quantitative research. The subjects in this study were 20 fifth grade students. The data collection method used questionnaires and descriptive tests. Data from pre-test and post-test results were analyzed using t test with correlated samples to determine the effectiveness of the product. The main results of this study indicate that the Balinese ethnomathematics-based animated video on flat building material significantly contributes to improving the critical thinking and metacognitive skills of grade V students. The effectiveness test showed a significant increase in students' critical thinking skills, as seen from their ability to analyze, evaluate, and solve problems related to the material. The implication of this research is to illustrate that developing ethnomathematics-based animated videos in the implementation of mathematics learning can train students' critical thinking skills and metacognitive abilities, especially on the material of flat areas.

Abstract

Ideally, learning should be implemented to support the achievement of competencies and foster student literacy, using learning models, media, and other educational tools that are tailored to the learning needs. However, in practice, many teachers are still found to use conventional learning models, where students only acquire knowledge that is directly transmitted by their teacher. This results in students lacking a good understanding of mathematical problem-solving concepts, making it difficult for them to grasp arithmetic concepts. This research aims to analyze the influence of the Ethnomathematics-based Problem Based Learning model on Numeracy Literacy abilities. This type of research is experimental research. This research uses a form of research (quasi experimental). The quasi- experimental design used was a non-equivalent post-test only control group design. The population of this study was all class V of SD Gugus 2, totaling 148 students. The sampling technique uses random sampling. The data collection method in this research uses a multiple choice test method. The data analysis used is quantitative descriptive analysis with t-test. The results of this research obtained tcount of 2.051 and ttable of 2.011 (tcount>ttable). Based on the research that has been conducted, it is concluded that there is a significant influence of the ethnomathematics-based Problem Based Learning model on the Numeracy Literacy abilities of fifth grade students at Gugus 2 Elementary School. The implications of this research can increase the numeracy literacy of fifth grade elementary school students which has an impact on a more of mathematics.
