Abstract

This study is motivated by the often monotonous teaching of Pancasila and Citizenship Education (PPPKn) in elementary schools, which tends to reduce students’ motivation to think critically and solve problems. An innovative learning model is needed to improve students’ understanding and interest. The objective of this research is to enhance the understanding and learning outcomes of Grade I students in PPPKn through the application of the Problem Based Learning (PBL) model at SD Negeri 067240 Medan Tembung. The study employed a Classroom Action Research (CAR) method conducted over two weeks in the even semester of the 2025 academic year, from 7 to 22 March 2025, involving 21 Grade I students. The research object was PPPKn learning outcomes after implementing the PBL model. The results show that a PBL approach designed to be enjoyable for students improved academic performance, with the average score increasing from 71.81 in cycle I to 80.52 in cycle II. The percentage of students achieving mastery also rose from 62% in cycle I to 86% in cycle II, surpassing the success indicator of 80% of students meeting the Minimum Mastery Criteria (Kriteria Ketuntasan Minimal, KKM). These findings demonstrate that the PBL model is effective in improving PPPKn understanding and learning outcomes in elementary school students.

Abstract

Heart failure is one of the leading causes of death worldwide. Early detection of heart failure risk is crucial to minimize its serious consequences. This study aims to compare the performance of two machine learning algorithms, namely Logistic Regression and K-Nearest Neighbor (KNN), in predicting heart failure using a dataset from the Kaggle platform. The research stages include data preprocessing, normalization, splitting into training and testing data, model implementation, and evaluation using a confusion matrix. Evaluation is based on accuracy, precision, recall, and F1-score metrics. The results show that Logistic Regression achieved an accuracy of 88.04% with an execution time of 0.022 seconds, while KNN achieved an accuracy of 85.51% with an execution time of 0.158 seconds. Logistic Regression outperformed in recall and F1-score, making it more effective for early detection of heart failure. Therefore, Logistic Regression is considered more optimal than KNN in the context of this study. However, Logistic Regression is not always superior to K-Nearest Neighbor, as prediction results highly depend on the characteristics of the specific case.

Abstract

This study aims to examine the effectiveness of the Teams Games Tournament (TGT) learning model integrated with the GASING method in improving elementary school students’ mathematical conceptual understanding. A quantitative approach was employed using a quasi-experimental design with a pretest–posttest control group structure. The population consisted of all fourth-grade elementary school students, with a sample of 60 students divided into an experimental group and a control group. The instrument used was an essay-based test designed to measure students’ conceptual understanding in mathematics. Data were analyzed through normality and homogeneity tests, followed by an independent sample t-test and N-Gain analysis. The findings reveal a statistically significant difference between students taught using the GASING-based TGT model and those taught through conventional instruction, with a significance value of 0.000 0.05. In addition, the experimental group achieved a high level of improvement (N-Gain = 0.73), while the control group showed a moderate increase (N-Gain = 0.41). These results suggest that the integration of the TGT model with the GASING method is effective in enhancing students’ conceptual understanding in mathematics. The study also highlights the potential of this approach as an innovative alternative that promotes more interactive, engaging, and meaningful learning aligned with the demands of 21st-century education.

Abstract

This study aimed to examine the effect of Quizizz-Based Digital Interactive Media on students' learning outcomes in learning Linear Equations at the junior high school level. The study employed a quantitative approach using a quasi-experimental design with a posttest-only control group design. The participants consisted of 60 eighth-grade students from SMP Negeri 2 Percut Sei Tuan, divided into an experimental group (30 students) and a control group (30 students). The experimental group received instruction using Quizizz-Based Digital Interactive Media, whereas the control group was taught using conventional instruction. Data were collected through a mathematics learning outcomes test that had been validated and tested for reliability. The data were analyzed using descriptive statistics and an Independent Samples t-test at a significance level of 0.05. The results revealed that the mean score of the experimental group (81.57) was higher than that of the control group (71.57). Furthermore, the hypothesis testing showed a statistically significant difference between the two groups (t = 15.402, p 0.001), indicating that the use of Quizizz-Based Digital Interactive Media significantly improved students' learning outcomes in learning Linear Equations. These findings suggest that integrating Quizizz into mathematics instruction creates a more interactive and engaging learning environment, thereby enhancing students' understanding of mathematical concepts and improving their academic achievement. Therefore, Quizizz-Based Digital Interactive Media can be considered an effective instructional medium to support innovative mathematics learning in junior high schools.
