<![CDATA[This study aims to determine the effect of interest in accessing social media on the concentration levels of Information Systems students from the 2023 cohort at the State Islamic University of North Sumatra. The research employed a quantitative method with a descriptive statistical approach and correlation analysis. Data were obtained from questionnaires voluntarily completed by 50 students. Each respondent provided a score for their interest in accessing social media (scale 1–5) and a daily concentration level score (scale 1–5). The collected data were processed using percentage analysis to observe the distribution of both variables, followed by correlation analysis. The results showed that most students fell into the moderate (30%) and high (20%) categories of social media interest. Meanwhile, concentration scores were predominantly in the moderate (22%) and high (20%) categories. A negative relationship trend was found between interest in accessing social media and concentration level; students who reported very high interest tended to have lower concentration levels, and vice versa. These findings are consistent with literature stating that social media is a major source of distraction that can reduce academic performance. Therefore, it can be concluded that high usage of social media has the potential to decrease students' concentration in daily activities.]]>

<![CDATA[Improving the quality of education in Indonesia continues to be pursued through various curriculum innovations, one of which is the Merdeka Curriculum, emphasizing project-based, flexible, and student centered learning. This study aims to analyze the influence of Merdeka Curriculum implementation on students’ interest in learning mathematics in the Computer and Network Engineering (TKJ) program at SMK Swasta Teladan Pematangsiantar. Learning interest is a critical variable as it contributes significantly to learning effectiveness and academic outcomes, especially in mathematics a subject often perceived as challenging. A quantitative approach was applied using a survey method with a Likert-scale questionnaire distributed to 65 respondents who had experienced the Merdeka Curriculum for at least one semester. Instrument validity and reliability were tested using SmartPLS, with results showing all constructs met convergent validity (AVE > 0.5) and reliability standards (Composite Reliability > 0.9). The coefficient of determination (R²) reached 0.6405, indicating that the Merdeka Curriculum explains 64.05% of the variance in students’ interest in learning mathematics. Hypothesis testing through bootstrapping revealed a path coefficient of 0.8003, a t-statistic of 19.2392, and a p-value of 0.000, confirming a significant and positive influence. This study concludes that the Merdeka Curriculum effectively enhances students’ interest in learning mathematics, although its success depends on the readiness of teachers, educational facilities, and supportive learning environments.]]>

<![CDATA[This study aims to examine the effectiveness of the Problem-Based Learning (PBL) model assisted by DiPin media on students' conceptual understanding in the topic of data collection. The research employed a quantitative method with a quasi-experimental design involving two classes at SD Tanwirul Qulub Kudus: class 5A as the experimental group using the PBL model assisted by media, and class 5B as the control group using only the conventional model. The instruments used were pre-test and post-test questions designed to measure students' mathematical conceptual understanding. Data analysis was conducted using five statistical tests: normality test, homogeneity test, ANOVA, Paired Sample t-Test, N-Gain, and Independent Samples t-Test. The results showed that learning with visual aids was more effective in improving students’ conceptual understanding and numerical abilities compared to conventional learning. The test data from classes 5A and 5B were normally distributed (p > 0.05) and had homogeneous variances (p = 0.411), fulfilling the requirements for parametric testing. The ANOVA test showed a significant difference between the two classes (p = 0.000; F = 31.370). In class 5A, the Paired Sample t-Test indicated a significant increase from pre-test to post-test (a 25-point increase; p = 0.000). The N-Gain score in class 5A was also higher (63.79%) compared to class 5B (23.51%). The Independent Samples t-Test confirmed these findings with significant results (p = 0.000), and the average post-test score was higher in class 5A (84.67) compared to 5B (65.67). Thus, learning using visual aids has been proven to be more effective in improving student learning outcomes.]]>

<![CDATA[Mathematical problem-solving ability is a critical 21st-century competency that needs to be developed from the early stages of education. However, field observations indicate that many elementary school students still struggle with solving problems related to fraction operations, especially when the problems are presented in contextual forms that require flexible application. This study aims to examine the effectiveness of the Contextual Teaching and Learning (CTL) model in improving the mathematical problem-solving skills of fifth-grade students at SDN 6 Cendono Kudus. The method used is quantitative with a quasi-experimental design and a Nonequivalent Control Group Design approach. The instruments employed were pre-test and post-test assessments covering problem-solving indicators based on Polya’s steps. The analysis results show a significant increase in post-test scores in the class using the CTL model, with a significance value of 0.028 (< 0.05) and an average N-Gain score of 0.3880 (moderate category). These findings indicate that the CTL model is effective in enhancing students’ mathematical problem-solving abilities, particularly because this approach links the material to real-life contexts, making learning more meaningful and relevant. This study recommends the implementation of CTL as an alternative instructional model that fosters active student engagement and conceptual understanding in elementary school mathematics.]]>
