Department of Mathematics Education. Faculty of Teacher Training and Education. Sultan Ageng Tirtayasa University. 2025. This research is motivated by the low mathematical reflective thinking skills of students, even though these skills have a very important role. One of the external factors that also influences students' mathematical reflective thinking skills is the implementation of learning models planned by teachers in the learning process. Therefore, a learning model is needed that is able to support the improvement of these skills. One of the learning models that is able to improve mathematical reflective thinking skills is the Problem Based Learning (PBL) model assisted by Quizizz. The purpose of this study was to determine the improvement in mathematical reflective thinking skills of students who received learning with the Problem Based Learning (PBL) model assisted by Quizizz with students who received learning with the Problem Based Learning (PBL) model. This research was conducted at SMAN 1 Cipanas. The method used was a quasi-experiment with a Pretest-Posttest Non-Equivalent Control Group Design. Sampling used a cluster random sampling technique. Data were obtained from the results of the pre-test, post-test, and student response questionnaires. The results showed that the increase in mathematical reflective thinking skills of students who received learning with the Problem Based Learning (PBL) model assisted by Quizizz was better than students who received learning with the Problem Based Learning (PBL) model. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/50096/1/LYDIA%20AMANDHA%20HAFFITH_2225210029_FULLTEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/19/LYDIA%20AMANDHA%20HAFFITH_2225210029_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/2/LYDIA%20AMANDHA%20HAFFITH_2225210029_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/3/LYDIA%20AMANDHA%20HAFFITH_2225210029_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/9/LYDIA%20AMANDHA%20HAFFITH_2225210029_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/4/LYDIA%20AMANDHA%20HAFFITH_2225210029_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/5/LYDIA%20AMANDHA%20HAFFITH_2225210029_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/6/LYDIA%20AMANDHA%20HAFFITH_2225210029_REFF.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50096/8/LYDIA%20AMANDHA%20HAFFITH_2225210029_LAMP.pdf identifier: Haffith, Lydia Amandha (2025) EFEKTIVITAS PENERAPAN MODEL PROBLEM BASED LEARNING (PBL) BERBANTUAN QUIZIZZ DALAM MENINGKATKAN KEMAMPUAN BERPIKIR REFLEKTIF MATEMATIS SISWA SMA.
