Populasi dalam penelitian ini adalah seluruh siswa kls VII SMP Negeri 3 Pagaralam, dan  Sampel penelitian adalah siswa kelas VII.A yang dipilih secara random sampling ? acak. Analisis data dilakukan secara deskriptif kuantitatif. Hasil analisis aktivitas siswa dalam 3 pertemuan diperoleh rata-rata 82,6% yaitu dalam kategori baik, sedangkan analisis hasil belajar siswa yang tuntas yaitu sebesar 87% termasuk kategori baik. Dan hasil analisis respon siswa dengan rata-rata 4 termasuk dalam kategori baik. Dari hasil penelitian dan analisis data diperoleh informasi bahwa aktivitas pembelajaran siswa setiap aspek yaitu aktivitas siswa selama pembelajaran, hasil belajar siswa dan respon siswa setelah mengikuti pembelajaran memenuhi kriteria baik.

The study's population consisted of all seventh-grade students at SMP Negeri 3 Pagaralam, with the research sample consisting of grade VII.A students chosen at random. Quantitative descriptive analysis was used to analyze the data. The examination of student activities in three meetings yielded an average of 82.6 percent, which is considered good, while the analysis of student learning outcomes yielded an average of 82.6 percent, which is also considered good. which is in the good group, whereas the total study of student learning outcomes, which includes the good category, is 87 percent. Also in the good category are the findings of the study of student replies with an average of 4.According to the findings of the research and data analysis, every area of student learning activities, including student actions during learning, student learning outcomes, and student replies after participating in learning, fulfilled good criteria. It may be concluded that employing the Reciprocal Teaching paradigm to learn mathematics is effective.Keywords: Effectiveness, Reciprocal Teaching, and Learning Outcomes","PeriodicalId":135040,"journal":{"name":"Jurnal Math-UMB.EDU","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123238707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
