Abstract

Purpose: The application of Kastolan's error analysis framework to the polar form of complex numbers remains limited, leaving a gap in the diagnostic literature for undergraduate mathematics education. This study aims to describe and classify the errors made by students when solving complex number polar form problems based on Kastolan's error stages: conceptual, procedural, and technical, to provide an empirical basis for more targeted instructional strategies in complex analysis.Method: A qualitative descriptive approach was employed. Data were collected through a written descriptive test and documentation of student answer sheets, which were analysed using Kastolan's error classification rubric. The research subjects were 21 seventh-semester Mathematics Education students at UIN North Sumatera who had completed the Complex Analysis course. Three students were selected through purposive sampling to represent each dominant error category.Findings: Three dominant error types were identified. Conceptual errors appeared in incorrect identification of arguments and angular quadrants. Procedural errors occurred when students bypassed the required polar form in division operations. Technical errors involved incorrect values of special angles and trigonometric function signs.Significance: These findings provide an empirical basis for lecturers to design targeted learning strategies addressing concept understanding, procedural order, and computational accuracy in complex number polar form instruction.

Abstract

Adversity Quotient (AQ) is widely theorized to predict student engagement in challenging mathematics learning, yet the assumption that this stable psychological trait manifests directly in observable classroom behavior has rarely been tested with direct observational data, particularly within Indonesian madrasah aliyah populations. This study aimed to (1) profile the AQ of Grade X students at a state Islamic senior high school along Stoltz's three categories and four CO₂RE dimensions, and (2) examine whether AQ category is reflected in observable activity during Problem-Based Learning (PBL). A descriptive quantitative design was applied to 20 purposively selected students. Data were collected via an adapted Adversity Response Profile (21 items; Gregory content validity = 0.952; Cronbach's α = 0.90) and a 17-indicator observation sheet covering the five PBL syntactic phases (1–5 scale). Three findings emerged. First, the AQ distribution was dominated by low- and moderate-resilience profiles (50% Quitters, 45% Campers, 5% Climber), converging strikingly with the larger ARP-ML survey of (Gradini & Noviani, 2025) and indicating a possibly structural pattern of low resilience among Indonesian mathematics learners. Second, the CO₂RE dimensions, although uniformly classified as High to Very High, were unevenly develop. Control and Reach were strongest (81.25%), while Origin and Ownership lagged (75.38%), with the weakest single item reflecting anxiety about group-leadership responsibility. Third, AQ category was essentially uncorrelated with observable PBL activity (r = 0.156). A Quitter recorded the second-highest activity score, while the only Climber recorded below-average activity. This trait-process dissociation suggests that AQ operates over cumulative learning timescales rather than within single sessions, and that group-based PBL may function as social scaffolding that compensates for individual trait limitations. The study contributes the first direct observational test of the AQ-PBL behavioral linkage in an Indonesian madrasah context and identifies Origin and Ownership as a priority pedagogical target.

Abstract

Critical thinking skills are one of the most important abilities that should be taught in math classes, however, these skills remain relatively low among some junior high school students. This study wants to find out how using the Teams Games Tournament method with a Snakes and Ladders game affects students' ability to think critically about algebra, as well as to determine the magnitude of that effect. The new idea in this study is combining the TGT model with the Snakes and Ladders game to help students develop their critical thinking skills in algebra, and the results are backed by an analysis of how effective the method is. The study used a quantitative method and followed a quasi-experimental approach with a nonequivalent control group setup. The study sample consisted of 60 seventh-grade students at Pahlawan Nasional Junior High School, comprising 30 students in the experimental class and 30 students in the control class. Data were collected using a critical thinking skills test and then analyzed through normality tests, homogeneity tests, an independent samples t-test, and Cohen’s d effect size. The t-test results showed a significance value of 0.000, which is less than 0.05, meaning there is a significant difference between the experimental group and the control group. Furthermore, the effect size analysis showed a very large effect. This result shows that using the TGT cooperative learning model with snakes and ladders as a teaching tool is good at helping students think more critically about algebra. Keywords: Teams Games Tournament (TGT), Snakes and Ladders, Critical Thinking Skills.

Abstract

The research aims to find out the effect of the gamification learning model using Quizizz on students’ mathematical problem-solving ability that focuses on Systems of Linear Equation Problems with Three Variables (SPLTV). This research used a quantitative method with a quasi-experimental design of nonequivalent control groups. The population was 660 tenth-grade students in MAN 2 Model Medan in the 2025/2026 academic year. Purposive sampling was used to take Class X-Q (n=32) as the experimental group and Class X-R (n=30) as the control group. Nine validated essay items (four pretest and five posttest questions) were used for data collection and met all standard psychometric criteria for validity, reliability, difficulty level, and discrimination index. Pre-analysis assumptions were satisfied, with the Shapiro–Wilk test confirming a normal distribution (0.202, 0.486, 0.172, and 0.133) and Levene’s test demonstrating variance homogeneity (0.414). The independent samples t-test revealed a statistically significant difference (p = 0.002 < 0.05), with the calculated t-value (t = 3.22) exceeding the critical t-threshold (2.000). Furthermore, the experimental cohort achieved a higher posttest mean score (86.78) than the control cohort (81.43), yielding a substantial effect size (Cohen’s d = 0.819). These outcomes indicate that integrating gamification via Quizizz substantially enhances students’ mathematical problem-solving skills. The distinct novelty of this research lies in implementing this digital gamification framework for SPLTV instruction while assessing problem-solving performance through Polya’s framework. Future investigations are encouraged to extend this model to alternative mathematical topics, diverse educational levels, or additional learning variables.

Abstract

Stunting masih menjadi salah satu masalah gizi kronis yang belum sepenuhnya teratasi di Indonesia, dengan pernikahan dini menjadi salah satu faktor risiko yang berkontribusi terhadapnya. Selain itu, perilaku hidup bersih dan sehat serta aktivitas fisik masyarakat pedesaan juga masih memerlukan penguatan melalui edukasi berkelanjutan. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan pemahaman dan keterampilan masyarakat Desa Sendang Rejo melalui tiga program: sosialisasi pencegahan stunting melalui pencegahan pernikahan dini, pelatihan pembuatan hand sanitizer, dan kegiatan senam sehat. Metode yang digunakan adalah pendekatan deskriptif kualitatif berbasis edukasi dan pelatihan komunitas (community-based health education), dengan teknik pengumpulan data berupa observasi partisipatif, dokumentasi, dan pencatatan daftar hadir. Hasil kegiatan menunjukkan peningkatan pemahaman siswa SMP mengenai bahaya pernikahan dini dan kaitannya dengan stunting, peningkatan keterampilan ibu-ibu PKK dalam membuat hand sanitizer secara mandiri, serta peningkatan kesadaran ibu-ibu desa terhadap pentingnya aktivitas fisik, meskipun partisipasi pada kegiatan senam mengalami penurunan pada pertemuan kedua. Kegiatan ini diharapkan dapat menjadi model edukasi kesehatan berkelanjutan berbasis masyarakat di wilayah pedesaan.
