This research utilizes a quantitative approach with a quasi-experimental design involving an experimental group and a control group. The sampling technique was conducted using purposive sampling. The research instruments consisted of critical thinking skills tests administered through pretests and posttests, supported by observation sheets and documentation. The results indicate that the implementation of differentiated learning has an impact on improving students' critical thinking skills. Descriptively, the average posttest score of students in the experimental group was higher than their pretest score and also higher than that of the control group. Based on the results of the Independent Samples t-Test, a significance value (Sig.) of 0.000 < 0.05 was obtained, indicating a significant difference in critical thinking skills between students in the experimental group and the control group. In general, most respondents showed improvement in critical thinking indicators, such as focusing on the problem, the ability to provide logical reasoning, understanding the context of the problem, and clarity in presenting arguments. Based on these results, it can be concluded that the implementation of differentiated learning has a significant effect on students' critical thinking skills in history learning. date: 2026-02 type: Thesis type: NonPeerReviewed format: text language: en identifier: https://eprints.untirta.ac.id/58778/1/Putri%20Wahyuningsih_2288210009_FULL%20TEXT.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/2/Putri%20Wahyuningsih_2288210009_CP.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/3/Putri%20Wahyuningsih_2288210009_01.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/4/Putri%20Wahyuningsih_2288210009_02.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/5/Putri%20Wahyuningsih_2288210009_03.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/6/Putri%20Wahyuningsih_2288210009_04.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/7/Putri%20Wahyuningsih_2288210009_05.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/8/Putri%20Wahyuningsih_2288210009_REF.pdf format: text language: en identifier: https://eprints.untirta.ac.id/58778/9/Putri%20Wahyuningsih_2288210009_LAMP.pdf identifier: WAHYUNINGSIH, PUTRI (2026) PENGARUH PENERAPAN PENDEKATAN PEMBELAJARAN BERDIFERENSIASI TERHADAP KEMAMPUAN BERPIKIR KRITIS SISWA DALAM PEMBELAJARAN SEJARAH KELAS XI HUMANIORA DI SMAN 1 CIKEUSAL.
