The process of learning mathematics still uses conventional methods where the teacher dominates the learning process, so still experience learning difficulties, especially understanding concepts and mastery of geometry which causes learning outcomes to decline. This causes students to be passive and only accept the teacher's explanation in other words students are not directed to think to find solutions to the problems at hand. Problem-based learning is learning that makes students active and can find their concepts and be more effective. In addition to problem-based learning. learning must use media that support a more effective teaching and learning process. The use of teaching aids is very influential on the success of the teaching and learning process. The type of this research is experimental research and quantitative approach. The population in this study were all students of class VII SMP Rewarangga while the sample was taken by random sampling totaling 14 students. The data analysis technique used Covariance Analysis (ANACOVA). The learning device meets the requirements of validity, and good sensitivity reliability. The learning tools include Learning Implementation Plans (RPP), Student Worksheets (LKS), and Learning Outcomes Test (THB). Based on the results of Anacova with homogeneity test, from the calculations obtained F count = 1.0787 and F table¬ with a significance level of 5% = 1.98, so F count < F table causes to accept H0 and reject H1 which shows the variance of the two samples is homogeneous. This shows that problem-based learning assisted by teaching aids can improve student learning outcomes for geometry material.

Mathematics learning in schools has not been linked to cultural concepts. Tea-eku dance is a cultural dance that contains a mathematical concept, the movement of the tea-eku dance contains a geometric concept. The purpose of this study is to apply tea-eku exercises through problem-based learning in increasing student interest and learning outcomes. The population in this study were all class VII students of SMP Adyaksa Ende for the 2022-2023 academic year. The sample in this study was class VII A as the experimental class and class VII B as the control class, each consisting of 13 students. The results of this study indicated that the learning interest of the control class students ranged from 55-78, while the experimental class with tea-eku dance media had scores ranging from 68 to 144 with an average score of 132.05 and a standard deviation. of 41,744. While student learning outcomes based on the results of the normality test using the Kolmogorov-Smirnov formula obtained normally distributed data (P = 0.000 <0.05). It can be interpreted that the application of tea-eku dance through problem-based learning can increase student interest and learning outcomes, seen from the statistical results F = 14.29 and F table = 4.28 with dk quantifier = 1 and dk denominator = 23, giving a value that significant.

Culture is something that cannot be avoided in social life because culture is a whole and comprehensive unity that becomes the basis for a relationship between individuals. This unity allows mathematical concepts to be embedded in cultural practices and recognizes that all people develop special ways of facilitating mathematical knowledge. culture-based mathematics learning is part of the way that is perceived to create meaningful and contextualized mathematics learning that is closely related to culture.in ethnomathematics, the relationship between mathematical concepts and culture will be deeply studied. Ethnomathematics is used to explore mathematical values and geometry concepts in gawi traditional dance. The purpose of this study is to describe the concepts of geometry implemented in gawi traditional dance. The concepts of geometry in gawi traditional dance will be reviewed based on the form, dance movements and dancers’ clothing. This study uses descriptive qualitative research with library data collection methods and field data. The data were analyzed descriptively and qualitatively. The results showed that the geometry concepts found in gawi traditional dance were devoted to the material of lines, angles and flat shapes. It was concluded that gawi traditional dance has ethnomathematics concepts, namely circles, parallel lines, acute angles, right angles, obtuse angles, triangles, and rectangles.
