Abstract

Penelitian ini bertujuan untuk menganalisis peran matematika dalam menyelesaikan tantangan ekonomi global saat ini melalui pendekatan studi literatur. Dengan semakin kompleksnya permasalahan ekonomi, seperti krisis keuangan, kesenjangan sosial, perubahan iklim, dan ketidakpastian geopolitik, diperlukan pendekatan yang lebih sistematis dan terukur. Penelitian ini mengkaji literatur yang relevan untuk mengeksplorasi penerapan metode matematika dalam analisis ekonomi, termasuk pemodelan, statistika, dan optimasi. Hasil penelitian menunjukkan bahwa integrasi matematika dalam ekonomi dapat meningkatkan akurasi prediksi, memperkuat analisis kebijakan, dan menghasilkan solusi inovatif terhadap tantangan global. Artikel ini juga menyoroti pentingnya kolaborasi lintas disiplin ilmu antara ahli matematika dan ekonom untuk menciptakan pendekatan yang lebih adaptif terhadap dinamika ekonomi modern. Dengan demikian, artikel ini memberikan wawasan teoritis yang dapat menjadi dasar untuk penelitian lebih lanjut di bidang ekonomi matematika.

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.
