This study aims to analyze the effectiveness of the Problem-Based Learning (PBL) model assisted by snakes and ladders game media on students' mathematical problem-solving ability in terms of learning interest on circle topics. This research employed a quasi-experimental method with a 2×2 factorial design involving 46 eleventh-grade students of SMA Taruna Gajah Mada Metro, divided into experimental and control groups. Data were collected through a problem-solving ability test and a learning interest questionnaire. Data were analyzed using two-way ANOVA. The results showed that the learning model had a significant effect on problem-solving ability. Students taught using PBL assisted by snakes and ladders media achieved higher scores than those taught conventionally. Learning interest also had a significant effect. However, there was no significant interaction between the learning model and learning interest ). The R Square value of 0.690 indicates that 69% of the variance in problem-solving ability is explained by the learning model and learning interest. Thus, PBL assisted by snakes and ladders media effectively improves students' mathematical problem-solving ability.

This study aims to analyze the effect of the Project based learning (PjBL) model integrated with the Realistic Mathematics Education (RME) approach on students’ numeracy skills in social arithmetic material. The study uses a quantitative approach with a quasi-experimental design of the NonEquivalent Control Group Design type. The research population is from one private senior high school in Metro City. The sample consists of 44 eleventh-grade students divided into an experimental class and a control class, each consisting of 22 students. The research instrument is a multiple-choice numeracy test that has met the criteria of validity and reliability. Data analysis is conducted through the Shapiro–Wilk normality test, Levene’s homogeneity test, and the Independent Sample t-test at a significance level of 0.05. The results of the study show a significant difference between the experimental and control classes (t(42) = −3.737; p = 0.001). The N-Gain score of the experimental class is 0.557 (moderate category), which is higher than the control class at 0.278 (low category). It is concluded that the integration of PjBL and RME is effective in improving students’ numeracy skills and can be used as an alternative contextual and meaningful mathematics learning approach.

This study was motivated by the low conceptual understanding and critical mathematical reasoning among vocational high school students, largely due to conventional instruction emphasizing procedural memorization, and the limited empirical evidence on deep learning interventions in vocational mathematics. This investigation aimed to examine the effect of the deep learning approach on vocational students' conceptual understanding and critical mathematical reasoning regarding exponential functions. A quasi-experimental posttest-only non-equivalent control group design was implemented. The sample comprised 40 tenth-grade students from SMK Ma'arif 1 Metro, assigned to an experimental group (n=19) receiving deep learning instruction and a control group (n=21) receiving conventional instruction. Data were collected using conceptual understanding and critical reasoning tests (10 multiple-choice items each), validated by four experts using Aiken's V (mean V=0.76, high; mean V=0.67, moderate), with reliability (Spearman-Brown=0.730). Data were analyzed using Multivariate Analysis of Variance (MANOVA). The findings revealed a statistically significant multivariate difference between groups (Wilks' Λ=0.519; F=17.123; p<0.05; partial η²=0.481). Univariate analyses confirmed significantly higher conceptual understanding (F=7.634; p<0.05; partial η²=0.167) and critical reasoning (F=18.937; p<0.001; partial η²=0.333) in the deep learning class. These findings suggest that deep learning pedagogy may foster vocational students' higher-order cognitive skills, encouraging mathematics educators to integrate mindful, meaningful, and joyful learning activities connected to industrial contexts. Penelitian ini dilatarbelakangi oleh rendahnya pemahaman konsep dan penalaran kritis matematis siswa SMK yang disebabkan oleh pembelajaran konvensional yang berorientasi pada hafalan prosedural, serta terbatasnya bukti empiris tentang intervensi deep learning dalam matematika vokasi. Penelitian ini bertujuan menganalisis pengaruh pendekatan deep learning terhadap pemahaman konsep dan penalaran kritis matematis siswa SMK pada materi eksponen. Metode kuasi-eksperimen dengan desain posttest-only non-equivalent control group digunakan. Sampel terdiri dari 40 siswa kelas X SMK Ma'arif 1 Metro, terbagi dalam kelompok eksperimen (n=19) yang mendapat pembelajaran deep learning dan kelompok kontrol (n=21) dengan pembelajaran konvensional. Data dikumpulkan menggunakan tes pemahaman konsep dan penalaran kritis (masing-masing 10 soal pilihan ganda), divalidasi oleh empat ahli menggunakan Aiken's V (rata-rata V=0,76 kategori tinggi; V=0,67 kategori sedang), dengan reliabilitas Spearman-Brown 0,730. Analisis data menggunakan MANOVA. Hasil penelitian menunjukkan perbedaan multivariat signifikan antara kedua kelompok (Wilks' Λ=0,519; F=17,123; p<0,05; partial η²=0,481). Analisis univariat mengonfirmasi bahwa kelas deep learning memiliki pemahaman konsep (F=7,634; p<0,05; partial η²=0,167) dan penalaran kritis (F=18,937; p<0,001; partial η²=0,333) yang lebih tinggi secara signifikan. Temuan ini mengindikasikan bahwa pendekatan deep learning berpotensi mengembangkan kemampuan berpikir tingkat tinggi siswa SMK, sehingga mendorong pendidik matematika untuk mengintegrasikan aktivitas pembelajaran mindful, meaningful, dan joyful yang terhubung dengan konteks industri.
