Abstrak Penelitian ini bertujuan untuk mengetahui ada tidaknya pengaruh model pembelajaran Treffinger terhadap kemampuan literasi numerasi siswa. Penelitian ini dilakukan di UPTD SMP Negeri 2 Gununugsitoli Tahun Pelajaran 2023/2024, dengan populasi seluruh siswa kelas VII yang terdiri dari 3 kelas. Sampel penelitian yang digunakan terdiri dari 2 kelas yang diambil secara simple random sampling, yaitu siswa kelas VII-A sebagai kelas eksperimen dan kelas VII-B sebagai kelas kontrol. Penelitian ini menggunakan metode eksperimen semu (quasi experimental) dengan pretest-posttest control group design. Instrumen penelitian berbentuk essay test untuk mengukur kemampuan literasi numerasi siswa. Analisis data yang digunakan adalah uji hipotesis dengan uji t independent. Berdasarkan hasil penelitian dengan uji hipotesis satu pihak, diperoleh nilai thitung = 4,379 dan nilai ttabel = 1,685. Karena thitung > ttabel atau 4,379 > 1,685 maka tolak H0 terima Ha, yang berarti “Ada pengaruh model pembelajaran Treffinger terhadap kemampuan literasi numerasi siswa”. Kata kunci: Treffinger, Kemampuan Literasi Numerasi Abstract This study aims to determine whether there is an effect of Treffinger learning model on students' numeracy literacy skills. This research was conducted at UPTD SMP Negeri 2 Gununugsitoli in the 2023/2024 academic year, with a population of all seventh grade students consisting of 3 classes. The research sample used consisted of 2 classes taken by simple random sampling, namely class VII-A students as the experimental class and class VII-B as the control class. This research used a quasi experimental method with pretest-posttest control group design. The research instrument was an essay test to measure students' numeracy literacy skills. The data analysis used was hypothesis testing with independent t test. Based on the research results with one-party hypothesis testing, the tcount value = 4.379 and the ttable value = 1.685 were obtained. Because tcount> ttable or 4.379> 1.685 then reject H0 accept Ha, which means “There is an effect of Treffinger learning model on students' numeracy literacy skills”. Keywords: Treffinger, Numeracy Literacy Skills

Abstrak Penelitian ini bertujuan untuk mengembangkan modul ajar berbasis etnomatematika untuk meningkatkan literasi matematis yang valid, praktis dan efektif untuk digunakan. Penelitian dilakukan di SMP Negeri 4 Tuhemberua Tahun Pelajaran 2023/2024 di kelas VII. Instrumen penelitian terdiri dari angket validasi ahli bahasa, materi, dan desain; angket respon peserta didik; angket respon guru dan tes hasil belajar peserta didik dalam menggunakan produk yang dikembangkan. Analisis data dilakukan secara kualitatif dan kuantitatif. Berdasarkan hasil penelitian, modul yang dibuat telah teruji sangat layak oleh validator ahli bahasa instrumen angket sebesar 98,66%, ahli bahasa pada modul sebesar 100%, ahli materi I sebesar 99,5%, ahli materi II sebesar 97,9%, ahli desain sebesar 94,2%. Modul yang dikembangkan sangat praktis digunakan dengan presentase 92,2%. Selanjutnya, modul juga efektif digunakan dengan presentase sebesar 87,10%. Berdasarkan hasil penelitian tersebut, modul berbasis etnomatematika tergolong efektif untuk meningkatkan literasi matematis siswa. Kata kunci: Modul, Model ADDIE, Etnomatematika, Literasi Matematis Abstract This study aims to develop ethnomathematics-based teaching modules to improve mathematical literacy that are valid, practical and effective for use. The research was conducted at SMP Negeri 4 Tuhemberua in the 2023/2024 academic year in class VII. The research instrument consisted of a validation questionnaire for linguists, materials, and design; student response questionnaire; teacher response questionnaire and student learning outcomes test in using the developed product. Data analysis was carried out qualitatively and quantitatively. Based on the results of the study, the module made has been tested very feasible by the validator linguist instrument questionnaire of 98.66%, language experts on the module by 100%, material experts I by 99.5%, material experts II by 97.9%, design experts by 94.2%. The developed module is very practical to use with a percentage of 92.2%. Furthermore, the module is also effective to use with a percentage of 87.10%. Based on the results of this study, the ethnomathematics-based module is classified as effective for improving students' mathematical literacy. Keywords: Module, ADDIE Model, Ethnomathematics, Mathematical Literacy
