Abstract

Based on a preliminary survey, students at Grade X SMK IT Darussalam Boarding School 01 Batam demonstrated a low understanding of mathematical concepts. This study aimed to examine: (1) the effect of Heyzine Flipbook-based digital learning media on students’ mathematical concept understanding, (2) the effect of conventional learning, and (3) the differences between the two methods. Using a quantitative approach, the population included all Grade X students in the 2025/2026 academic year. Purposive sampling was applied, with Grade X TKJ A (24 students) as the experimental class and Grade X TKJ B (19 students) as the control class. Data were collected through essay tests, consisting of three validated and reliable items. Data analysis involved assessing normality and homogeneity, as well as conducting hypothesis tests. The results revealed that: (1) Heyzine Flipbook significantly improved students’ understanding of mathematical concepts, (2) conventional learning also showed an effect on students’ understanding, though at a lower level, and (3) a significant difference was found between the two approaches, with Heyzine Flipbook proving more effective in enhancing students’ mathematical concept understanding.

Abstract

The educational intervention program integrates theoretical knowledge with classroom practice at SD Negeri 018 Galang. This study examined the effect of a problem-based learning (PBL) model on students’ literacy and numeracy skills. A pre-test and post-test experimental design was employed with a sample of 15 students. The instruments consisted of expert-validated literacy and numeracy tests. Data were analyzed using normality tests, Wilcoxon signed ranks tests, and paired sample t-tests. The pre-test results indicated that literacy scores were not normally distributed (p = 0.010), while post-test literacy scores showed a normal distribution (p = 0.165). Numeracy scores, both before and after the intervention, were normally distributed. Of the 15 participants, 12 students experienced a decline in literacy scores (Z = −2.458, p = 0.014). A significant difference was found between pre-test and post-test scores (t = −3.287, p = 0.005), suggesting the need for careful evaluation of the learning model. Overall, the findings revealed a decrease in literacy outcomes, indicating that the applied strategies require adjustment to better support learning. In contrast, numeracy outcomes showed significant improvement, reflecting effective problem-based learning through contextual activities and educational games related to daily experiences.
