Abstract

Mathematics is often called uninteresting and considered abstract. One way that can be used to introduce mathematics is by relating it to daily life or special local culture, which is called ethnomathematics. Ethnomathematics is a combination of mathematical elements with cultural aspects and social context in society. One of the cultures that exists in society is weaving. In South Tapanuli itself there is a woven cloth which is a local cultural heritage, namely the Sipirok Woven cloth. In this research, the science implemented is Transformation Geometry. Transformation Geometry is a science that discusses change, these changes can be in the form of changes in shape or changes in presentation based on matrices and images. This research is included in the type of exploratory research, namely exploring woven fabric motifs that can be used in learning Transformational Geometry. The process of compiling one element of the sipirok motif can be carried out in various ways and in a certain sequence of transformations. The transformation that will be used to compose sipirok batik in this article is reflection.

Abstract

This research is motivated by the low learning outcomes of class VIII mathematics students. One of the causes of low student learning outcomes is the use of inappropriate learning strategies that are less interesting for students in the learning process. The purpose of this study was to determine and analyze the influence of mind map-based expository learning strategies using Canva on the mathematics learning outcomes of class VIII students at Pandan 1 Middle School. One strategy that is considered capable and in line with technological developments is an expository learning strategy based on mind maps using Canva. The research population, namely all class VIII students and the sample consisted of two classes, namely the experimental class and the control class. The research instrument used a test. While data processing and data analysis were carried out using the t-test. Based on data analysis, the post-test questions given to students to measure students' cognitive abilities obtained an average value of 76.11 for the experimental class and 64.69 for the control class. The results of the hypothesis test obtained tcount>ttable, namely 2.163>1.99897 with a significance level of 5%, so Ha is accepted and H0 is rejected, which means that there is a significant influence on the expository learning strategy based on mind maps using Canva on the mathematics learning outcomes of class VIII students of SMP N 1 Pandan.
