Abstract

Abstract: This study aims to: (1) explain the significant effect of STEM-based mathematics learning on students’ critical thinking skills; (2) explain the significant effect of STEM-based mathematics learning on students’ creative thinking skills; and (3) explain the significant effect of STEM-based mathematics learning on students’ critical and creative thinking skills at SMA IT Yarsi Mataram. The research employed a quantitative approach with a survey research design, which was selected to obtain systematic and structured data regarding students’ characteristics. The study was conducted at SMA IT Yarsi Mataram, with the population consisting of all eleventh-grade students, while the research sample comprised 53 students. The data collection instrument was a questionnaire distributed manually. The collected data were analyzed using multivariate regression analysis. The results indicate that: (1) STEM-based mathematics learning does not have a significant effect on students’ critical thinking skills, as shown by a univariate test significance value of 0.971, which is greater than the 0.05 significance level; (2) the STEM approach does not have a significant effect on students’ creative thinking skills, with a univariate test significance value of 0.147, exceeding 0.05; and (3) STEM-based mathematics learning does not show a significant effect on students’ critical and creative thinking skills simultaneously, as indicated by a Wilks’ Lambda significance value of 0.276, greater than 0.05. The implications of this study suggest that STEM-based mathematics learning cannot yet be considered an effective alternative learning strategy for developing higher-order thinking skills, particularly critical and creative thinking, highlighting the need for further research to explore learning models better suited to the characteristics of high school students.

Abstract

This study examined the effectiveness of STEM-based learning integrated with the Project-Based Learning (PjBL) approach in enhancing eighth-grade students’ relational mathematical understanding at SMP Negeri 1 Batukliang during the 2025/2026 academic year. A quantitative approach with a quasi-experimental method employing a pretest–posttest control group design was used. The population comprised all eighth-grade students of SMP Negeri 1 Batukliang (206 students). Using purposive sampling, two classes were selected: Class VIII3 as the control group and Class VIII4 as the experimental group, involving a total of 56 students. Data were collected through an essay-type test measuring relational mathematical understanding, administered at the pretest and posttest stages. Data analysis employed descriptive and inferential statistics using SPSS version 27, including normality and homogeneity tests, N-Gain analysis, and an Independent Samples t-test. The results showed that the average N-Gain score of the experimental class was 0.4906 (moderate category), which was higher than that of the control class at 0.2889 (low category). Furthermore, the t-test revealed a significance value of 0.000 (< 0.05). These findings indicate that STEM-based learning integrated with the PjBL approach is effective in improving students’ relational mathematical understanding.

Abstract

The illiteracy rate (ILR) serves as an indication of educational attainment, representing the percentage of individuals aged 15 and older who lack reading and writing skills. Despite a reduction in Indonesia's ILR to 3.33% in 2024, the objective of eliminating it entirely remains a priority to fulfill the fourth aim of The Sustainable Development Goals (SDGs) by 2030. This research seeks to estimate Indonesia's rate of illiteracy by examining relevant elements, including the number of individuals living in poverty, mean years of schooling, and gross enrollment ratio. The data is obtained from the BPS-Statistics Indonesia. This study employs spatial regression, utilizing an area-based methodology to capture spatial impacts among regions and analyze them with R software. The analysis results indicate that a) the chosen weighted matrix is k-Nearest Neighbor, b) the selected spatial model for the illiteracy rate in Indonesia is the Spatial Durbin Model (SDM), and c) mean years of schooling and gross enrollment ratio within a province significantly affect the illiteracy rate in that province, which may indirectly elevate the illiteracy rate in neighboring regions.

Abstract

One important indicator for evaluating the well-being and standard of living of people in a certain area is the life expectancy index. The goal of this study is to model the life expectancy in the Province of West Nusa Tenggara (NTB). The number of impoverished individuals, adjusted per capita spending, and the average number of years of education are the independent variables used. The data comprised a panel from 10 districts/cities in NTB for the year 2019–2023, obtained from BPS-Statistics NTB Province. The applied analytical method was spatial panel regression, utilizing queen contiguity and a customized weighted matrix based on transportation routes. According to the analysis, a) the spatial autoregressive panel model (SARFEM) was chosen as the model to study life expectancy in NTB; b) life expectancy in one region is directly impacted by life expectancy in adjacent regions; and c) a region's life expectancy is significantly impacted by its mean years of education and adjusted per capita expenditure, both of which can raise life expectancy in nearby regions. This link underscores the necessity of enacting policies that prioritize advancements in education and economic conditions in a particular location, while also taking into account the wider geographical context, to promote general well-being and life expectancy in adjacent regions.
