Abstract

This study aims to explore geometric ideas in traditional food called Tumpi-Tumpi, a typical Bugis Makassar cuisine, and to develop problem-solving abilities using the Iceberg Realistic Mathematics Education (RME) model. This study used a qualitative study with descriptive exploration. Data was collected through observation, interviews, and documentation. Based on the design of Miles and Huberman, the data analysis technique consisted of data reduction, data presentation, and conclusion/verification. According to data collection results, the traditional Bugis-Makassar cuisine Tumpi-Tumpi contains ethnic mathematical components (geometrical concepts), namely, the plane figure of an equilateral triangle, and is used to solve mathematical problems. The Iceberg RME math technique utilized "the model of" and "the model for" to determine an equilateral triangle's features, area formula, and perimeter. Iceberg-based ethnomathematics collaboration may enhance high school student's interest in learning.

Abstract

This study aims to determine student learning outcomes based on self assessment and assessment conducted by the teacher, knowing the difference in the value of self assessment and assessment carried out by the teacher, and knowing the difference in the average score of the test before and after the implementation of the self assessment. Measurement of student learning outcomes was carried out on the class VIII learning group of SMP Negeri in Makassar. Samples were taken by random sampling technique. Data retrieval method using the instrument used in this study is a self assessment sheet and learning outcomes test. The value of student learning outcomes based on self assessment obtained an average value of 84.60 and the value of student learning outcomes based on assessment conducted by the teacher obtained an average value of 80.83. The difference in the value of self assessment and assessment conducted by the teacher was measured through inferential statistical analysis using SPSS 20.0 and the results of the sig. (2-tailed) 0,000 <α = 0.05 which means that H0 is rejected and H1 is accepted so that the hypothesis is accepted. The difference in the average test scores before and after the application of self-assessment was also measured through inferential statistical analysis using SPSS 20.0 and the results of the sig. (2-tailed) 0,000 <α = 0.05, which means that H0 is rejected and H1 is accepted, which means the hypothesis is accepted. Based on the results of the study it can be concluded that there are differences in the value of self assessment and assessment conducted by the teacher and there are differences in the average scores of tests before and after the application of self assessment.
