GEOMETRIC TRANSFORMATION ON CARVINGS OF TORAJA TONGKONAN HOUSES

This research aims to examine the mathematical concepts in traditional Tongkonan houses' carving and provide information about the meaning of each carving in the Tongkonan house. The research method used is the qualitative research method. The results of the study are obtained by observation and interview. The results showed that it turns out, in some Toraja carvings, contain the concept of transformational geometry, namely reflection. The information also obtained that the carvings in the Tongkonan house are very loaded with meaning, especially about advice, prayer, or hope to all members of the Tongkonan.

Student Approaches Resulting from Integration of Cultural Context into Transformation Geometry

The purpose of this study is to investigate how students’ in senior grade of the high school participate in and interpret the transformational geometry activities integrated with cultural context. 5 students in senior grade participated in this study, all of whom live in Aydın district of Turkey. The main design of the study is qualitative. Participant students of the study involved in 9 different rotational geometry and culture integrated activities, 7 of which were performed as student activity sheets, 2 of which were performed as cultural games. 2 of the activities were constructed as a result of pilot study applied to 28 senior students by their math teacher. To collect data about how students participated in and made interpretations about the activities; various data collection tools such as observation, field notes, interview, audio recording and student activity sheets were used. The collected data were analyzed by qualitative descriptive analysis techniques. The results were presented as tables, figures constructed by students and direct quotations. Lastly, at the end of this study students were said to recognize the hidden mathematics in the objects from daily life, games with cultural background and history, and both in Turkish culture and other cultures.

ANALISIS MOTIF ANYAMAN DAN AKTIVITAS FUNDAMENTAL MATEMATIS DALAM SENI MENGANYAM DI DESA PLAOSAN KABUPATEN KEDIRI

Mathematical contextualization is interpreted as identifying the existence of mathematics developed by different cultural groups. The existence of ethnomathematics in education offers a learning approach that connects mathematics with the local cultural wisdom of the community. The main focus of this research is to identify ethnomathematics in woven handicrafts in Plaosan Village, Kediri Regency. This research is qualitative descriptive research. Data were collected using observation, documentation, interview, and literature study techniques. The results showed that there were ethnomathematics in woven handicrafts in Plaosan Village. The mathematical elements that can be found in the woven motifs are the concept of the plane, the concept of lines and the relationships between lines, the concept of angles, and the concept of transformational geometry. The fundamental mathematics activities that can be found in the weaving activities are counting, measuring, designing, locating, playing, and explaining.

PENGEMBANGAN MODUL BERBANTUAN GEOGEBRA PADA PERKULIAHAN GEOMETRI TRANSFORMASI

This study aims to develop and find out the quality of teaching materials in the form of teaching modules assisted by the geogebra program on transformational geometry lectures. The Geogebra-assisted transformation geometry module is structured systematically and accompanied by steps to solve transformation problems using Geogebra. This type of research is development research (Research and Development / R & D). The development model is 4D which consists of four stages, namely defining, designing, developing and disseminating. In this study, only three steps were carried out, namely the defining, the design, and the development stage. The research instrument is a module validation sheet. The product assessment was carried out by 3 validators consisting of 2 material experts and 1 media expert who was a lecturer in the mathematics education study program. The results showed that the assessment of the two validators of material experts on the geogebra-assisted transformation geometry module developed had an average total score of 3.38 with very good criteria, while for validators media experts had an average total score of 3.21 with very good criteria. Very good criteria from the results of the validation of media experts and material experts showed that the geometry module of geogebra-assisted transformation was valid and suitable for use as teaching material in lectures.
