Abstract

This research is important to explore the potential of GeoGebra as an innovative learning tool in mathematics education. Amid rapid technological advancements, GeoGebra is expected to serve as an effective solution to help students understand complex mathematical concepts. By utilizing a literature review approach, this study collects data from various relevant sources regarding the application of GeoGebra in mathematics education. Based on the reviewed studies, the use of GeoGebra significantly contributes to improving students' ability to understand abstract concepts, especially in geometry. However, challenges exist in its implementation, such as limited technological infrastructure in schools and insufficient teacher training. With improved access to technology and teacher training, GeoGebra can be optimized as an effective tool for teaching mathematics.

Abstract

This study aims to evaluate the effect of integrating the Problem-Based Learning (PBL) model with an open-ended approach on the creative thinking skills of 10th-grade students in mathematics, specifically in the topic of Quadratic Functions. The research was conducted at Cahaya Medan Private High School, involving six 10th-grade classes. Two classes were selected as the sample: Class X-2, which participated in the experimental group and received instruction through the PBL model with an open-ended approach, and Class X-3, the control group, which followed traditional teaching methods. Each group consisted of 34 students. A quasi-experimental design was employed, incorporating pretest and posttest evaluations, along with five validated open-ended questions to assess the outcomes. Data analysis was performed using a t-test. The experimental group achieved an average posttest score of 84.94, while the control group scored 77.09. The t-test results showed that the PBL model, when combined with the open-ended approach, significantly improved the students' creative thinking abilities in learning Quadratic Functions.

Abstract

Studi ini mengkaji penggunaan bahasa gaul di kalangan remaja di jejaring sosial. Tujuan dalam penelitian ini adalah untuk mengetahui pengaruh penggunaan bahasa gaul terhadap penggunaan Bahasa Indonesia pada kalangan remaja di Indonesia. Bahasa gaul adalah bentuk bahasa informal yang populer untuk ekspresi diri remaja dan identitas kelompok. Metode observasi dan wawancara digunakan untuk mengumpulkan data remaja usia 13-18 tahun. Hasil penelitian menunjukkan bahwa bahasa gaul memfasilitasi komunikasi dan penciptaan komunitas online yang inklusif. Namun penggunaan bahasa gaul juga dapat menimbulkan kesenjangan komunikasi antar generasi. Penelitian ini menyoroti peran bahasa gaul dalam dinamika sosial remaja dan memberikan wawasan tentang komunikasi digital dan perkembangan bahasa.
