Abstract

This research is based on the problem of the low mathematical visual thinking ability in learning mathematics. To overcome this, research was carried out using a STEM-based Project-Based Learning (PjBL-STEM) model. This study examines the problem of improving visual mathematical abilities among students who receive mathematics learning with the STEM-based Project-Based Learning (PjBL-STEM) model. This research is quasi-experimental, the design used is the Nonequivalent Control Group Design using the Purposive Sampling technique. The population in this study were high school students in Bandung Regency in the academic year 2021/2022, with the research sample being high school students in class X. The instrument used in the study was a visual mathematical ability test. Data analysis was carried out quantitatively by using the Independent Sample t-test. The results showed that (1) Overall the application of the PjBL-STEM learning model could improve students' mathematical visual thinking abilities, (2) Improved mathematical visual thinking skills of students whose learning using the PjBL-STEM learning model was significantly better than students who learned using conventional learning models.Penelitian ini didasarkan pada permasalahan masih rendahnya kemampuan visual thinking matematis dalam pembelajaran matematika. Untuk mengatasi hal tersebut, dilakukan penelitian dengan menggunakan model Project-Based Learning berbasis STEM (PjBL-STEM). Penelitian ini mengkaji masalah peningkatan kemampuan visual matematis antara siswa yang mendapat pembelajaran matematika dengan model Project-Based Learning berbasis STEM (PjBL-STEM). Penelitian ini merupakan penelitian kuasi eksperimen, desain  yang digunakan adalah Nonequivalent Control Group Design dengan menggunakan teknik Purposive Sampling. Populasi dalam penelitian ini adalah siswa SMA di Kabupaten Bandung Tahun Pelajaran 2021/2022, dengan sampel penelitiannya adalah Siswa SMA kelas X. Instrumen yang digunakan dalam penelitian berupa tes kemampuan visual matematis. Analisis data dilakukan secara kuantitatif dilakukan dengan menggunakan Independent Sample t-test. Hasil penelitian menunjukkan bahwa, (1) Secara keseluruhan penerapan model pembelajaran PjBL-STEM dapat meningkatkan kemampuan kemampuan visual thinking matematis siswa, (2) Peningkatan kemampuan visual thinking matematis siswa yang pembelajarannya menggunakan model pembelajaran PjBL-STEM secara signifikan lebih baik dibandingkan dengan siswa yang pembelajarannya menggunakan model pembelajaran konvensional.
