Abstract

When solving math problems, students make spontaneous movements called gestures. The purpose of this research is to find out the variations of gestures that appear when students solve math problems related to rotational geometry based on local wisdom. The qualitative approach used in this research is a descriptive research type. Test questions, documentation results, observations, and interviews were used as research instruments. The subjects of this study were four students in class XI for the 2022/2023 academic year at SMA Negeri Balung. The results showed that the group of students with high abilities used gestures more than students with low abilities. Students with high ability in solving math problems use 11 iconic gestures, 8 metaphoric gestures, and 24 deictic gestures. Meanwhile, the group of students with low abilities used 7 iconic gestures, 6 metaphoric gestures, and 12 deictic gestures. Based on the distribution of the number of student gestures when solving math problems, the gesture that appears the most is the deictic gesture, and the one that appears the least is the metaphoric gesture.

Abstract

Reflective abstraction is a process of reflection on previously learned concepts and applied in new situations. The purpose of this study is to describe the reflective abstraction ability of junior high school students in solving math problems in terms of mathematical ability. In this study using qualitative research type. The data sources for this study were 4 students of class VIII, namely 2 students with high ability and 2 students with low ability. The results showed that students who have high ability, recognition level to remember and identify previous activities related to the problem at hand. At the representation level, students can translate information into mathematical models correctly. At the structural abstraction level, students can solve problems correctly, and are able to overcome difficulties in solving problems. At the structural awareness level, students are able to provide arguments about the results of the answers that have been done. While students with low ability, at the recognition level are able to remember previous activities related to the problem at hand. At the representation level, students are able to translate information into mathematical models, but students are less careful and wrong so that at the structural abstraction level students are able to solve problems, but the final results obtained are not correct. At the structural awareness level, students are able to solve and explain the steps in the problem. Based on the results of the study, teachers should guide students by providing problem exercises that can increase reflective abstraction, especially considering student responses and learning outcomes collected from high and low ability students. For this reason, further research needs to be carried out with other student data sources.

Abstract

Movement in a dance is a visual symbol full of meaning conveyed to be accepted by dance lovers from the whole dance performed. The selection of dance movements is related to the mathematical concept of illustrating its meaning (ethnomathematics). In addition, there is a mathematical literacy process of geometry concepts revealed in dance movements. This becomes a meaningful symbol that becomes a wealth of dance movements that are increasingly interesting to present. The purpose of this research is to identify the ethnomathematics of lahbako dance in the perspective of mathematical literacy of geometry concepts. qualitative research with a descriptive approach to explain the data and its discussion. Data collection methods of interviews, observation, and documentation with data validity test source triangulation. Subjects 2 people from Arutala dance studio and Hastarini. The results obtained are dance movements that come from different habits and interpretations of dancers but the actual meaning of the movements is the same. Ethnomathematics in lahbako dance successfully illustrates the meaning of the movements conveyed in lahbako dance through hand, finger, foot, and body movements that modify into lines, acute and obtuse angles, and triangular and rectangular fields. The mathematical literacy perspective of the geometric concepts of lines, angles, and fields is visualized conceptually, the application of real contexts of daily life, geometric thinking, and the delivery of mathematical language helps in illustrating the message conveyed in a lahbako dance, namely the activities of tobacco farmers. Further research recommendations for dance movements that jump or repeatedly back and forth and the count used by dancers in each movement.
