Abstract

This research is a continuation of the article Development of Trigonometric Material Teaching Materials through the RME Approach (Meika et al., 2023). Before the teaching materials that have been developed are used, it is necessary to know in advance the effectiveness of the teaching materials. Therefore, it is necessary to trial the use of these teaching materials in a class to determine their effectiveness. The purpose of this study is to determine the effectiveness of RME-based LKPD on the ability to understand concepts in terms of learning completeness. The method used is Design Based Research (DBR) with the Plomp development model consisting of three stages, namely: Preliminary Research, Prototyping Stage and Assessment. This article contains the results of the assessment phase. At the assessment stage, a final test was carried out and filled out a student response questionnaire to determine the effectiveness of the LKPD that had been developed. The effectiveness of LKPD is seen from the completeness of student learning outcomes. The final test results showed that the average score of class X Science 1 was 78 with three students who did not complete KKM. KKM Madrasah Aliyah Mathla'ul Anwar Menes Centre is 71. The percentage of students who achieved completion was 85.72%. Therefore, LKPD products have been effective in developing students' ability to understand mathematical concepts. The results of the student response questionnaire showed that the average percentage of all aspects assessed was 77.87% with the category "Good".

Abstract

This research aims at developing local instruction theory for learning combinations by using Realistic Mathematics Education (RME). This research uses a design research approach, Hypothetical Learning Trajectory (HLT), developed from a series of activities to obtain a better understanding about combinations at Senior High School (SHS) students. Theoretical development is supported by an interactive process in designing learning activities, conducting teaching experiment and conducting retrospective analysis to contribute to combinations of Local Instruction Theory (LIT). An understanding of combinations emerges and develops during classroom learning activities. Qualitative analysis of teaching experiments shows that by using local instruction theory teaching materials that characterize RME students are able to develop their understanding about a combination.

Abstract

The claim that the golden ratio appears in nature is frequently used as a context for mathematics learning; however, such claims require rigorous examination through precise variable definitions and appropriate analysis. This study critically examined whether internode-distance patterns in water spinach (Ipomoea aquatica) approximate the golden ratio. The objectives were to: (1) describe the pattern of five consecutive internode distances across 30 water spinach stems, (2) examine the closeness of adjacent-distance ratios to φ = 1.618, and (3) translate the findings into an inquiry-STEM activity for ratio learning. The data comprised 150 distance measurements and 120 adjacent paired ratios collected using AR Meter, a smartphone-based augmented reality measurement application. The analysis retained directional ratios to identify positional changes and used symmetric ratios, defined as the longer distance divided by the shorter distance, to evaluate proximity to φ. Differences among the five positions were tested using the Friedman test, while stem-level geometric means were compared with φ using the Wilcoxon signed-rank test. The results showed significant differences in internode distance by position, χ²(4) = 22.744, p < 0.001, Kendall’s W = 0.190. The arithmetic mean of the 120 symmetric ratios was 1.629, which appeared close to φ but was influenced by two extreme ratios, 11.25 and 11.67. Only 11 of the 120 ratios (9.17%) fell within a 5% tolerance of φ. Therefore, the data did not support a consistent golden-ratio pattern in water spinach internode distances. The educational value of this study lies in using an unconfirmed popular claim as a context for teaching measurement, reciprocal ratios, robust statistics, and evidence-based argumentation through inquiry-STEM.
