Therefore, it is necessary to increase the ability to think reflectively mathematically with various learning approaches that present problems in everyday contexts. The learning approach in question is numeracy-based. For this reason, learning with a numeracy approach can use learning media in the form of learning E-LKPD with numeracy activities. Therefore, researchers developed a numeracy-based E-LKPD to improve high school students' mathematical reflective thinking abilities. The type of research used is R&D with the ADDIE model (Analyze, Design, Development, Implementation, And Evaluation). The subjects in this research were class XI students at SMA Negeri 6 Serang City. The trials carried out were small-scale trials with 10 people and large-scale trials with 32 people. The instruments used were validation sheets, responses, disposition questionnaires for mathematical reflective thinking abilities, and student value data. The validity results obtained from material experts were 76% and 84% from media experts obtained from the two experts in the valid category. Then, the practicality results obtained from the responses of educators and students obtained an average result of 80.08% in the practical category. The results of the disposition questionnaire for mathematical reflective thinking abilities were obtained at 71% in the good category. Test results N-Gain From the value data before and after using E-LKPD based on numeracy activities, a score of 57% was obtained, which was interpreted as quite effective in improving mathematical reflective thinking skills. So that E-LKPD based on numeracy activities to improve mathematical reflective thinking abilities can be said to be valid, practical, and quite effective in improving high school students' mathematical reflective thinking abilities. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/48697/1/Muhammad%20Faishal%20Rachman_2225190031_Full%20Text.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/2/Muhammad%20Faishal%20Rachman_2225190031_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/3/Muhammad%20Faishal%20Rachman_2225190031_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/4/Muhammad%20Faishal%20Rachman_2225190031_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/5/Muhammad%20Faishal%20Rachman_2225190031_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/6/Muhammad%20Faishal%20Rachman_2225190031_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/7/Muhammad%20Faishal%20Rachman_2225190031_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/8/Muhammad%20Faishal%20Rachman_2225190031_Lamp.pdf format: text language: id identifier: https://eprints.untirta.ac.id/48697/9/Muhammad%20Faishal%20Rachman_2225190031_Ref.pdf identifier: RACHMAN, MUHAMMAD FAISHAL (2025) PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (E-LKPD) BERBASIS AKTIVTAS NUMERASI UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR REFLEKTIF MATEMATIS SISWA SMA.
