Abstract

This paper investigates proofing techniques which are used in algebraic structure research and how to apply those techniques. This paper also investigates the reasoning behind the application of the techniques and their effects. The data was collected by reviewing some algebraic structure textbooks used recently. Books reviewed were domestic and foreign books. The results of the review process were noted and documented, and then finally transcribed and coded. The review process of each book was carried out twice. The data obtained were then triangulated, to get the valid data, and eventually used for further analytical purposes. The results obtained show that not all the proofing techniques were used in the proofing process in the algebraic structure research. They tended to use the same technique in every proofing activity. This might be due to mastery of proofing techniques, preferences for certain proofing techniques, lack of information about the development of various proofing techniques. The resulting impact can be identified from the steps of proofing, meanwhile, if it is conducted using another technique, it can reduce the steps, is more acceptable also comprehensible

Abstract

Congklak is a traditional game that has a long history and contains philosophies in its development. The aim of this study is to explore congklak from ethnomathematics side so that they can know the cultural value of traditional congklak games and their connection to mathematics, describe the mathematical elements contained in congklak and to find out the role of congklak in mathematics learning. This research uses qualitative research approach with type of ethnographic research supported by literature research methods. Data collection techniques that researchers do use interviews, observations, documentation, and literatur studies. This research instrument is the researcher himself using recorder aids, cameras, and stationery. The results of ethnomathematic exploration in traditional congklak games are seen from the mathematical elements, namely there are arithmetic, geometry, graphs, and probability. Cultural elements in congklak are honesty (sportive), accuracy, patience, and sharing. Congklak in mathematic learning act as ethnomatematics-based learning media. The results of this study are as information for teachers to make congklak as a medium of mathematics learning both as conventional and digital gamesÂ
