Abstract

This study aims to determine the effect of the application of the Problem Based Learning (PBL) model assisted by Educaplay media on students' mathematical problem-solving ability in the Two-Variable Linear Equation System (SPLDV) material. This study uses a quantitative approach with the experimental method and the One Group Pretest-Posttest design. The subject of the study is 30 students. The instrument used is a mathematical problem-solving ability test in the form of description questions. The data were analyzed using the Shapiro-Wilk normality test, the paired sample t-test, the Wilcoxon test, and the N-Gain analysis. The results showed that there was an increase in the average score from the pretest of 41.7 to 67.1 in the posttest. The results of the hypothesis test showed a significant difference between the pretest and the posttest (p < 0.001) with an effect size value of 4.55 which is in the very large category. Thus, it can be concluded that the Educaplay-assisted PBL model has a significant and effective effect in improving students' mathematical problem-solving skills.

Abstract

Percentages are one of the important concepts in mathematics that are widely used in various contexts of daily life such as economics, commerce, and decision-making. However, various studies show that the concept of percentage is still a material that is quite difficult for students and prospective mathematics teachers to understand. These difficulties are generally related to the understanding of the basic concept of percentage, the use of the percent symbol (%), and the ability to relate the percentage value to the reference value in a problem. This study aims to analyze various percentage calculation strategies that can be carried out quickly and accurately based on the results of previous research. The method used in this study is a literature study by reviewing various scientific articles from SINTA-accredited national journals and international journals that are relevant to the topic of percentages in mathematics learning. Data is collected through documentation techniques by examining and analyzing research findings related to the percentage calculation strategy. The results of the study show that the use of mental calculation strategies, understanding the basic concept of percentages, and the use of visual models can help improve students' ability to calculate percentages more effectively and efficiently. Therefore, the right calculation strategy is essential to support the understanding of the concept of percentages in mathematics learning.
