Abstract

Ethnomatematics as link between culture and mathematics is a multicultural mathematical activity that uses culture in making connections with mathematics topics so as to motivate students to preserve their own culture while learning mathematics. The purpose of this reasearch are to explore ethnomathematics in Gajah Oling’s batik based on geometric concepts. The type of reaserch is qualitative with an ethnographic approach. Data collection methods used are observation and interviews. The subject of this reasearch is a design maker Gajah Oling’s batik. This research focuses on intersesting discovery from the exploration results, that is making pattern of Gajah Oling’s batik shirt. In the process of making pattern of Gajah Oling’s shirt, ethnomathematics seen on design and measuring activities. In desiging activities geometric concepts such as translation and reflection emerge, while in measuring activities, design makers use mathematics to determine the design size so that the fabric meeded to make a shirt can be minimized as little as possible.Keywords: Ethnomatematics, cocoa farmers, culture.

Abstract

The purpose of this study is to describe the profile of algebraic thinking in junior high school students in solving mathematical problems in terms of cognitive style (reflective and impulsive). The subjects used were class VIII B Arjasa 1 Junior High School as many as 25 children. Data collection in this study used two test questions, namely the MFFT test (Matching Familiar Figure Test), algebra test and interviews with four students representing different cognitive styles (reflective and impulsive) .
