Abstract

The Jong Sailboat is a traditional game of the Riau islands' Malay culture. This game developed in various areas whose territories have beaches. In the Jong Sailboat game, mathematical elements can be explored, especially in the Jong Sailboat's shape. Mathematical practice in culture is known as ethnomathematics. Ethnomathematics studies can be obtained through exploration, exploring the field to get more knowledge from a situation. Through Jong Sailboat's exploration, mathematical concepts and elements are found in it. So this research aims to explore ethnomathematics in the shape of a Jong Sailboat as a traditional game in the Riau Islands. This type of study is qualitative research with an ethnographic approach. The subjects in this study were makers of traditional game crafters and the shape of the Jong Sailboat. Data collection is done by interview, observation, and documentation, with the main instrument of study, are the researchers themselves. The data is then analyzed by referring to Miles and Huberman's design by reducing data, presenting data, and conclusions/verification. The results found a mathematical practice in geometrical shapes in triangles, rectangles, and mathematical concepts in the way of translations, acute angles, right angles, trigonometry, straight lines, and slope. This exploration can enrich ethnomathematics science, which is also found in the form of Jong Sailboats.

Abstract

The learning process is one of the essential things in students' success in obtaining the material they get, especially during the Covid-19 pandemic. Many students cannot carry out face to face in class. Therefore educators must provide the right method. So, students can understand the material it provides. Educators have used various ways not to feel bored, using the e-learning method. The study aims to determine Electronic-Based Mathematics Learning (EBML) for students' creative thinking ability in Sekolah Tinggi Keguruan dan Ilmu Pendidikan (STKIP) Muhammadiyah Pagaralam. The method used is the quasi-experimental method in the one-shot case study category. The study population was all students of the Mathematics Education Study Program of STKIP Muhammadiyah Pagaralam. The study results because of the indicator creative thinking indicators: fluent review 69.44%, flexible thinking 71.76%, original thought 74.92%, and elaborative thinking 88.19%. It is obtaining an average value of students amounted to 76,08%, it is categorized as useful. EBML is designed to simplify and shorten the learning process. So, it becomes more efficient. It is also to train students to be more independent in gaining knowledge to reach a wider geographical area, both in discussions and references. The EBML is applied to students’ creative think in understanding the material presented.
