Instrumen dalam penelitian ini terrdiri dari tes dan wawancara, tes kesalahan berupa uraian soal cerita, dan wawancara dilakukan kepada 4 siswa yang banyak melakukan kesalahan. Data dianalisis dengan deskriptif yaitu menggambarkan tentang suatu subjektif. Dari hasil tes kesalahan yang dilakukan oleh siswa berdasarkan indikator polya dengan kesalahan diantaranya yaitu kesalahan memahami soal dengan sebesar 98,8%, kesalahan menyusun rencana sebesar 86,6%, kesalahan melaksanakan rencana sebesar 63 %, kesalahan memeriksa kembali solusi yang diperoleh sebesar 88,3%. Faktor penyebab siswa melakukan kesalahan dalam menyelesaikan soal aritmetika sosial berbentuk cerita adalah karena siswa tidak memahami masalah pada soal, karena kebiasaan siswa tidak menulis apa yang ditanya dan diketahui pada soal, karena siswa tidak dapat menyusun informasi dari soal untuk merubah kedalam model matematika, karena siswa tidak mengetahui rumus yang digunakan dalam soal, karena siswa bingung untuk melakukan langkah-langkah penyelesaian, dan kurang teliti dalam melakukan perhitungan jawaban pada soal, karena kebiasaan siswa setelah menyelesaikan jawaban tidak memeriksa kembali hasil yang diperoleh, dan tidak menarik kesimpulan pada soal, Hasil penelitian ini menunjukan bahwa masih banyak kesalahan yang dilakukan oleh siswa dalam menyelesaikan soal aritmetika sosial berbentuk cerita.\u0000Kata kunci : analisis, kesalahan, aritmetika, sosial\u0000Abstract\u0000This study aims to describe the types of errors made by students, and to find out what causes students to make mistakes in solving story problems on the subject of social arithmetic.

Improvement of student learning outcomes can be seen from the average test scores of learning and training results of students cycle I to cycle III, namely 59.24; 70,41; 80,76 with the percentage of classical learning completeness from cycle I to cycle III which is 36%; 56%; 80%.Keywords: Learning Activity, Learning outcomes,  Realistics Mathematics Education (RME).","PeriodicalId":135040,"journal":{"name":"Jurnal Math-UMB.EDU","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125868583","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}

Oleh karena itu diperlukan alternatif model pembelajaran yang tepat untuk meningkatkan aktivitas, pola berpikir kritis dan kreatif serta hasil belajar matematika siswa. Salah satu alternatifnya adalah pembelajaran melalui pembelajaran kooperatif tipe STAD. Tujuan penelitian ini adalah untuk mendeskripsikan penerapan pembelajaran kooperatif tipe STAD yang dapat meningkatkan hasil belajar siswa dan mendeskripsikan tanggapan siswa dalam penerapan pembelajaran kooperatif tipe STAD. Penelitian ini menggunakan desain penelitian tindakan kelas. Teknik pengumpulan data yang digunakan adalah observasi, angket, dan tes. Setelah dilakukan analisis data diperoleh kesimpulan bahwa: 1) Penerapan pembelajaran melalui pembelajaran kooperatif tipe STAD ( Student Team Achievement Division ) yang dilakukan dalam penelitian ini efektif, karena dapat meningkatkan hasil belajar siswa pada mata pelajaran matematika, mata pelajaran penerapan trigonometri pada siswa kelas X IPA6 yang berjumlah 40 orang. Hal ini terlihat pada persentase hasil aktivitas siswa pada pembelajaran tindakan I mencapai 86,36% dan pada tindakan II mencapai 89,09% dengan predikat sangat baik, dan nilai rata-rata hasil tes akhir tindakan I mencapai 67,3% dan pada Tindakan II mencapai 72,25% dengan persentase nilai rata-rata yang ditetapkan sebesar 65% yang berarti telah mencapai kriteria keberhasilan. 2) Berdasarkan hasil angket respon siswa diketahui bahwa respon siswa terhadap pembelajaran penerapan trigonometri melalui pembelajaran kooperatif tipe STAD sangat positif.Kata kunci: hasil belajar, penerapan trigonometri, kooperatif, STAD. AbstractThe average result of student tests on the material for applying trigonometry is low, namely 52 and this does not reach the KKM at SMA Negeri 22 Palembang, which is 6. Therefore, an alternative learning model is needed. appropriate for increasing activity, critical and creative thinking patterns as well as student mathematics learning outcomes. One alternative is learning through cooperative learning type STAD . The purpose of this study is to describe the application of cooperative learning type STAD which can improve student learning outcomes.and describe student responses in the application of cooperative learning type STAD to improve learning outcomes. This study used a classroom action research design. Data collection techniques used were observation, questionnaires, and tests. After data analysis was carried out , it was concluded that: 1) The application of learning through cooperative learning type STAD ( Student Team Achievement Division ) which was carried out in this study was effective, because it can improve student learning outcomes in mathematics, the subject of the application of trigonometry in class X IPA6, amounting to 40 people. This can be seen in the percentage of student activity resul","PeriodicalId":135040,"journal":{"name":"Jurnal Math-UMB.EDU","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117202259","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}
