Rosa afliana (2026). pengaruh model problem based learning (pbl) berbantuan geogebra terhadap hasil belajar dan kecemasan matematika siswa di sma negeri 11 banda aceh. [skripsi. universitas syiah kuala]. dibawah bimbingan dra. suryawati, m.pd., dan cut khairunnisak, s.pd., m.sc. hasil belajar dan kecemasan matematika merupakan dua aspek penting dalam pembelajaran matematika. berdasarkan observasi awal di sma negeri 11 banda aceh, hasil belajar siswa masih belum optimal dan kecemasan matematika masih tergolong tinggi. salah satu alternatif pembelajaran yang dapat diterapkan untuk mengatasi permasalahan tersebut adalah model problem based learning (pbl) berbantuan geogebra. penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar dan penurunan kecemasan matematika siswa sebelum dan sesudah diterapkan model problem based learning (pbl) berbantuan geogebra. penelitian ini menggunakan pendekatan kuantitatif dengan jenis pre-eksperimen dan desain one-group pretest-posttest design. populasi penelitian adalah seluruh siswa kelas x sma negeri 11 banda aceh tahun ajaran 2025/2026. sampel penelitian berjumlah 34 siswa yang dipilih menggunakan teknik cluster random sampling. instrumen penelitian berupa tes uraian dan angket kecemasan matematika. analisis data menggunakan uji normalitas shapiro-wilk dan uji paired sample t-test pada taraf signifikansi 0,05. hasil penelitian menunjukkan bahwa data berdistribusi normal. nilai thitung hasil belajar sebesar 9,18 dan kecemasan matematika sebesar 4,20, keduanya lebih besar daripada ttabel sebesar 1,692. hasil tersebut menunjukkan adanya peningkatan hasil belajar dan penurunan kecemasan matematika siswa setelah diterapkan model problem based learning (pbl) berbantuan geogebra. dengan demikian, model problem based learning (pbl) berbantuan geogebra berpengaruh positif terhadap peningkatan hasil belajar dan penurunan kecemasan matematika siswa. kata kunci: problem based learning (pbl), geogebra, hasil belajar, kecemasan matematika.

Rosa Afliana (2026). The Effect of the GeoGebra-Assisted Problem Based Learning (PBL) Model on Students' Learning Outcomes and Mathematics Anxiety at SMA Negeri 11 Banda Aceh. [Skripsi. Syiah Kuala University]. Under the guidance Dra. Suryawati, M.Pd., and Cut Khairunnisak, S.Pd., M.Sc. Learning outcomes and mathematics anxiety are two important aspects that influence students' success in mathematics learning. Based on preliminary observations at SMA Negeri 11 Banda Aceh, students' learning outcomes were still not optimal, and their mathematics anxiety remained relatively high. One alternative learning model that can be implemented to address these problems is the Problem Based Learning (PBL) model assisted by GeoGebra. This study aimed to determine the improvement in students' learning outcomes and the reduction in mathematics anxiety before and after the implementation of the Problem Based Learning (PBL) model assisted by GeoGebra. This study employed a quantitative approach using a pre-experimental method with a One-Group Pretest-Posttest Design. The population consisted of all tenth-grade students at SMA Negeri 11 Banda Aceh in the 2025/2026 academic year. The sample comprised 34 students selected through cluster random sampling. The research instruments included an essay test and a mathematics anxiety questionnaire. The data were analyzed using the Shapiro Wilk normality test and the Paired Samples t-Test at a significance level of 0.05. The results showed that the data were normally distributed. The calculated tvalue for learning outcomes (9,18) and mathematics anxiety (4,20) were both higher than the critical tvalue (1,692). These findings indicate that students' learning outcomes improved and their mathematics anxiety decreased after the implementation of the Problem Based Learning (PBL) model assisted by GeoGebra. Therefore, the Problem Based Learning (PBL) model assisted by GeoGebra had a positive effect on improving students' learning outcomes and reducing their mathematics anxiety.
