Hasil penelitian menunjukkan bahwa siswa mengalami kesulitan yang pada proses matematisasi horizontal dan vertikal dalam menyelesaikan soal cerita materi bangun ruang sisi datar. Kesulitan pada proses matematisasi horizontal adalah tidak mampu mengidentifikasi konsep matematika yang relevan dan tidak membuat model matematika. Kesulitan pada proses matematisasi vertikal adalah tidak menggunakan representasi matematis dan tidak melakukan matematika formal. ABSTRACT Learning difficulties can occur because students view mathematics as a scary and difficult topic. One of the topic that are difficult for students to understand is a geometry flat side, because studying it requires a high level of concentration and accuracy. In solving the problem of building a geometry flat side, it is necessary to take advantage of real problems in everyday life so that students are able to understand in a structured manner. Mathematization process is a process to mathematical a problem or to model the problem mathematically and to build a mathematical concept from the problem. This study aims to describe the difficulties of students in the process of mathematizing word problem on the geometry flat side. The research subjects, which consisted of 4 students of class VIII G, were students who had received learning topic of geometry flat side. The type of research used is descriptive qualitative. The research procedure carried out in this study went through three stages including (1) The preparation stage. (2) Implementation phase (3) Data analysis phase. The results showed that students experienced difficulties in the horizontal and vertical mathematization process in solving word problems on the geometry flat side. The difficulty in the horizontal mathematization process is not being able to identify relevant mathematical concepts and not making mathematical models. The difficulty in the vertical mathematization process is not using mathematical representations and not doing formal mathematics.","PeriodicalId":316436,"journal":{"name":"Wilangan: Jurnal Inovasi dan Riset Pendidikan Matematika","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123658400","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}

Berdasarkan hasil wawancara terhadap pendidik mata pelajaran di sekolah didapat fakta bahwa pendidik dalam mengembangkan lembar kerja masih sedikit dan tidak menuntut kemampuan pemahaman konsep matematis peserta didik. Oleh karena itu perlu adanya bahan ajar berupa LKPD untuk pendidik matematika dan peserta didik. Dengan demikian tujuan penelitian ini adalah mengembangkan bahan ajar untuk pengembangan lembar kerja peserta didik. Penelitian pengembangan ini menggunakan metode pengembangan yang diadaptasi dari Sugiyono (2015). 7 tahapan utama dilakukan dalam penelitian ini. Empat orang uji ahli dari dua orang uji ahli matematika, uji ahli pendidikan, dan uji ahli media telah melaksanakan pengujian terhadap LKPD yang dikembangkan. Berdasarkan uji ahli pendidikan, bahan ajar LKPD tersebut dinilai sangat valid dengan persentase 90%. Untuk uji ahli pendidikan, persentase yang didapat sebesar 85,8% dengan kriteria sangat valid. Sedangkan untuk uji ahli media mendapatkan persentase sebesar 85,3% dengan kriteria sangat valid. LKPD tersebut juga diujicobakan kepada 10-20 orang peserta didik SMP kelas VIII. Hasil respon peserta didik berdasarkan angket terbuka dan tertutup terhadap LKPD dengan materi sistem persamaan linear dua variabel tersebut yaitu sebesar 87,71% dengan kriteria sangat valid dan menarik. Berdasarkan hasil tersebut, LKPD dengan Problem Based Learning terhadap kemampuan pemahaman konsep matematis sudah layak digunakan sebagai salah satu referensi dalam pembelajaran yang telah sesuai dengan Kurikulum 2013 serta mampu mengasah kemampuan pemahaman konsep matematis.","PeriodicalId":316436,"journal":{"name":"Wilangan: Jurnal Inovasi dan Riset Pendidikan Matematika","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134105179","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}
