With the problem of having difficulty understanding mathematical ideas experienced by students, due to the abstract nature of ideas and their rarity in our everyday existence. Therefore, the need arises for a Realistic Mathematics Education (PMR) method that offers learning from an authentic setting. This research aims to conduct a literature review related to Realistic Mathematics Education (PMR) and the effectiveness of the ethnomathematics-based Realistic Mathematics Education approach. Systematic Literature Review (SLR) is the research method chosen for this research. The data collection process includes collecting and analyzing every publication published between 2007 and 2023 that discusses ethnomathematics-based realistic mathematics education. The journals used in this research were 15 national and international journals indexed by SINTA and SCOPUS. Research findings show that PMR techniques build mathematical concepts by utilizing real-world contexts. Everyday existence occurs within a cultural framework. Learning with an ethnomathematics-based PMR approach is effective to use because it can improve various types of mathematical abilities.

This study addresses the critical issue of insufficient spatial thinking abilities among students, which significantly affects their performance in higher-order thinking skills (HOTS) tasks, particularly in trigonometry. Focusing on 11th-grade students in Tanjungpinang, Indonesia, the research investigates how spatial thinking influences the ability to solve trigonometric comparison problems. Employing a mixed-method approach, the study integrates quantitative data from the Higher-Order Thinking Skills in Trigonometric Comparisons Assessment (HOTS-TCA) with qualitative insights from post-test interviews. Rasch Model Analysis evaluates the quality of an assessment instrument by providing measures of respondent abilities and item difficulties, fit statistics to ensure model alignment, reliability, and separation indices for consistency, a Wright Map for visualizing the relationship between skills and difficulties, and checks for unidimensionality and potential item bias to ensure fairness and validity. The Rasch analysis further confirms the reliability and validity of the HOTS-TCA instrument, highlighting its effectiveness in measuring spatial thinking across varying ability levels. The study finds that students with high spatial ability excel in visualizing geometric relationships but struggle with complex three-dimensional tasks. In contrast, medium-ability students have difficulties with mental manipulation and real-world applications, and low-ability students face significant challenges in basic visualization and interpreting geometric structures, leading to frequent misconceptions.

In general, integral calculus courses are difficult for students because the problems involved require strong problem-solving skills. For university students, integral calculus courses also require them to do self-regulated, or independent, learning. Another aspect that makes learning difficult for these students is their mathematical beliefs and prior knowledge. This study aims to see how different types of mathematical beliefs affect self-regulated learning in terms of students' prior knowledge. This research was conducted on students in a mathematics education study program at a private university in Tangerang with a sample of 120 students. This research is an ex post facto quantitative study using a two factorial design. The variables in this study consisted of independent variables in the form of mathematical beliefs, the moderator variable in the form of students’ prior knowledge, and the dependent variable in the form of self-regulated learning. The results obtained are: (1) self-regulated learning by students with logical consistency mathematical beliefs is higher than students with memorized and procedural beliefs, (2) there is an interaction between mathematical beliefs and prior knowledge towards self-regulated learning, (3) student in the high prior knowledge gorup logical consistency beliefs had higher self-regulated learning than students with memorized and procedural beliefs, and (4) self-regulated learning in the low mathematics prior knowledge group with logical consistency beliefs is lower than students with memorized and procedural beliefs.BAHASA INDONESIA ABSTRACT: Mata kuliah kalkulus integral pada umumnya masih menjadi kesulitan bagi mahasiswa karena permasalahan yang terkandung membutuhkan pemecahan masalah yang kuat.

This study employs an empirical methodology to investigate the calculation of indices for determining the unit costs of equivalent education. This study compares the Construction Cost Index (CCI) and Purchasing Power Parity (PPP) in order to evaluate their relative effectiveness. A review of the existing literature on these indices reveals a need for more refined calculation and comparison methods. The study employs data from the Indonesian Central Statistics Agency (CSA), including CCI and PPP figures from 2021 and allocations for School Operational Assistance (SOA) for non-formal education in 2022, to examine the relative significance of the CCI and PPP. The findings indicate that the CCI exerts a greater influence than the PPP. Furthermore, the application of a relative importance approach through multiple regression analysis reveals a robust positive correlation between the CCI and PPP, underscoring their intricate interrelationship.
