Abstract

Ethnomatematics is a study that contains mathematical ideas from traditional societies which are applied to certain societies which are practiced by cultural groups. One of the existing cultures in Tuban district is Gedog batik. Gedog batik ethnomatematics is a study that examines the application of mathematical concepts to Gedog batik. The purpose of this research is to examine how the mathematical concepts of the Gedog batik motif. The method used in this research is exploration with an ethnographic approach. The results showed that the Gedog batik motif contains mathematical elements, including the concepts of symmetry, transformation (reflection, translation, rotation) and congruence. By knowing the mathematical elements of Gedog batik, it is hoped that it can help understand mathematical concepts based on contextual problems that arise in the Gedog batik culture.

Abstract

Algebraic thinking skills for students are important to improve in mathematics learning. Algebra is also closely related to other branches of mathematics. Because every branch of mathematics uses mathematical symbols. So it can be said that algebra is one of the keys to success in learning mathematics. The purpose of this study was to determine algebraic thinking skills in junior high school students in grade VII in terms of logical thinking skills. this type of research is a qualitative study. The subjects in this study consisted of 3 junior high school students in grade VII, each of whom occupied the abstract operasional stage, the transitional stage and the concrete operational stage which were determined through a logical thinking ability test (TKBL). After finding a subject that corresponds to the stage of logical thinking ability, the subject is given an algebraic thinking test. Data collection using written test collection using written test questions and interviews. The results of this study state that the subject of the abstract operational stage is good in algebraic thinking skills, the transitional skills and the concrete operational stage subject is lacking in algebraic thinking skills.
