Abstract

Learning and teaching will be meaningful if the students take an active role in finding the concept. The involvement of various contexts that are close to and known by students in learning and teaching mathematics motivate their learning and students see the importance of learning math. The use of cultural object such as tabuik in learning mathematics with Realistic Mathematics Education (RME) approach becomes an innovative learning at grade VIII of SMPN 4 Pariaman. Learning of polyhedrons (prism and pyramid) topic appropriate with the tabuik, which is built from several polyhedrons. This experimental study aims to see the comparison of student learning outcomes taught by RME approach using tabuik with student learning outcomes taught by conventional learning. The result of data analysis showed that the result of mathematics learning outcomes of students taught by Approach of Realistic Mathematics Education (RME) using tabuik in learning of polyhedron topic higher than mathematics learning outcomes of students taught by conventional learning at grade VIII SMPN 4 Pariaman. In addition, learning with RME approach and tabuik foster positive students' activities and positive attitudes in mathematics learning also appreciate their own culture.Keywords: Realistic Mathematics Education (RME), tabuik, learning outcomes.

Abstract

The mathematical concept on cultural objects is one of the objects of study in the study of ethnomathematics. This study aims to uncover mathematical concepts in the ornaments found in the rumah gadang and the development of ornaments. This qualitative research uses participatory observation techniques and documentation to obtain data. The results showed that there were geometrical concepts in the ornaments and the development of the rumah gadang ornaments. The concepts of geometry seen in ornaments include the use of two-dimensional such as square, rectangular, rhombic, circle, ellipse and polygons. Two-dimensional shape are also arranged using certain patterns. The development of ornament forms is carried out using the principles of congruence, tessellation, symmetry patterns and geometric transformations (translation, reflection, rotation, and dilation). The results of this study can be used as a reference for teachers in mathematics learning and ethnomathematics research on cultural objects.Keywords: ethnomathematics, ornaments of rumah gadang

Abstract

This paper discuss about practicality of product that are result of developmental research of learning device based on flipped classroom to improve mathematical problem solving ability for XI grade students of Senior High School on transformation material. This developmental research using Tjeerd Plomp model development procedure consisting of 3 stages, namely preliminary analysis stage, prototype development stage, and assessment phase. Data of practicality are collected by observation sheets, interview and students quosionare. The result show that learning device (lesson plan, learning video, student work sheet) are practically on learning geometry transformation based on flipped classroom. Keyword: practicality, learning device of geometry transformation, flipped classroom
