Abstract

Mathematical concepts that can be used to explore mathematics in culture. The term used to associate mathematics and culture is ethnomathematics. Cultural elements such as regional dances, regional songs, customs, regional languages, traditional games, traditional food and regional clothing need to be preserved because they can be integrated into the learning process. One of them is the culture found in the Batak tribe, especially the Batak Karo. The richness of the Batak Karo tribe in terms of traditional clothing motifs, namely the beka reed and uis nipes yeast western. The aim of this research is to explore the concept of flat shapes in the beka buluh and uis nipes ragi barat motifs of the Batak Karo tribe. The research was carried out in Tiga Binanga, Karo Regency, North Sumatra Province in December 2023 with sources from the traditional Batak Karo tribe. The data analysis used is observation and interviews. This research is qualitative research with an ethnographic approach. The results of this research found the mathematical concept of flat shapes in the motifs of beka buluh and uis nipes Ragi Barat Batak Karo tribe.

Abstract

This research aims to provide a new innovation in mathematics learning, because based on the results interviews, researchers found that mathematics learning is less innovative, learning strategies are still monotonous and learning methods are less interesting so that students' cognitive growth is not optimal. The Sudoku game is a logic-based puzzle game that can improve junior high school students' cognitive abilities in a mathematics learning environment. Sudoku trains the student's mind to absorb several strategies and pieces of information in a short time. Apart from that, this game can also help improve students' memory and concentration. Sudoku can be used as a game choice that can increase students' concentration in learning mathematics.

Abstract

The aim of this study is to test the direct influence of teacher performance in building student conceptual understanding of mathematical reasoning, as well as the direct impact of teacher's performance in constructing student's understanding of conceptual, mathematic reasoning and mathematics literacy on students' learning results. This study took the subjects of the students of the eighth grade in the 3rd grade state high school in Karo district of a total of 255 students. This research is a study of quantitative methods using ex-post facto approaches of a corrosional nature. Data is collected using tests, then processed and analyzed with path analysis techniques. The results of this study show that: (a) there is a direct influence of the teacher's performance in building conceptual understanding of the student's mathematical reasoning; (b) there has been a direct impact of the teachers' performance in constructing the students' understanding of conceptual reasoning and mathematics literacy on student learning outcomes.

Abstract

Geogebra is one of the applicative software that can be used as a learning medium for mathematics in the 4.0 era. This application can help teachers in creating learning media especially in the geometry material as well as geogebra can facilitate mathematical teacher in making graphical illustrations and geometric designs so that it is expected to arouse the spirit of students in learning math. The method used in this research is a literature review. The purpose of this research is (1) to explain the definition of geogebra; (2) to demonstrate the use of Geogebra as a learning medium in improving the ability of teachers in teaching mathematics in the era 4.0. The result of this study is that geogebra is a dynamic and interactive program that allows for a lot of exploration of a mathematical concept especially on the material of geometry transformation.
