Abstract

Good learning design is a learning design that is adjusted to the needs of students in order to achieve the learning objectives that have been set. This study aims to analyze students' understanding of mathematical concepts in Realistic Mathematic Education learning with students who do not apply hypothetical learning trajectory to trigonometric comparison material. Quantitative research method with phonomology design. The subjects of this study were 28 students of class X IPA at SMA 1 Boyolali. The data and data sources in this study consisted of the results of observations of test answers, and interview results. Data collection techniques from written test results (diagnostic tests), interviews and observations. The results of the study obtained the results of the Mann-Whitney test on the post-test value data showed a significance value of 0.000 on students' conceptual understanding. This significance value is smaller than the significance level of α = 0.05 so that there is a significant difference in the average value of conceptual understanding between the experimental and control classes. So it can be concluded that students in the experimental class who were given mathematics learning treatment using RME-based HLT had a better conceptual understanding than students in the control class who were not given treatment.

Abstract

Batik Ceplok Kasatrian is an Indonesian cultural heritage that is full of philosophical meaning but is less known by the younger generation. Therefore, the integration of batik in mathematics learning can be one of the strategies to preserve tradition of batik culture. This research aims to explore mathematical concepts, such as geometry, algebra, arithmetic, and statistics, in Batik Ceplok Kasatrian motifs. This research uses qualitative-ethnographic. The subject of this study is the Batik Ceplok Kasatrian motif. Data validity is obtained through source triangulation, while data analysis includes reduction, presentation, and conclusion. The exploration process is carried out by answering four main questions: "Where do I begin exploring?", "How can I discover it?", "How will I know if it has discovered something important?", and "How can I make sense of it?". The results show that of the four mathematical concepts, only two mathematical concepts are found in this batik, namely geometry and arithmetic. Geometry subconcepts include transformation (reflection, translation, dilation) and plane geometry (line segments, symmetry, congruence). Arithmetic subconcept includes integers (odd-even numbers). These findings can be integrated into mathematics learning through the development of ethnomathematics-based assessments oriented towards High Order Thinking Skills.
