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 mengeksplorasi aplikasi akselerator nuklir dalam terapi dan penelitian kanker (2019–2025) menggunakan Schematic Literature Review (SLR). Dengan menyaring 200 jurnal, 20 artikel utama diidentifikasi, yang menyoroti kemajuan dalam teknologi akselerator. Temuan menekankan transmutasi isotop untuk pengelolaan limbah nuklir dan Spektrometri Massa Akselerator (AMS) untuk pengukuran isotop yang tepat. Studi ini juga meneliti Terapi Penangkapan Neutron Boron (BNCT) dalam mengobati glioblastoma, yang menunjukkan potensinya untuk mengurangi tumor sekaligus meminimalkan kerusakan pada jaringan sehat. Selain itu, kemajuan dalam sumber neutron kompak dan sistem akuisisi data untuk akselerator linier (LINAC) menghadirkan peluang klinis baru. Penelitian ini menggarisbawahi peran penting akselerator nuklir dalam meningkatkan pengetahuan ilmiah dan perawatan medis.

Abstract

This study aims to analyze the differences in Indonesian spelling errors among students based on their regional dialects at Al Razi Sinar Harapan  Junior High School. The research method employed is a combination of qualitative and quantitative approaches involving interviews with Indonesian language teachers and questionnaires distributed to students. The findings indicate variations in spelling errors among students from different regions, as well as the influence of regional dialects on spelling error patterns. Additionally, the impact of social media and technology contributes to students' spelling errors. This research provides a deeper understanding of the factors affecting Indonesian spelling errors among students.
