MENINGKATKAN KEMAMPUAN KOMUNIKASI MATEMATIS MENGGUNAKAN PENDEKATAN PENDIDIKAN MATEMATIKA REALISTIK INDONESIA (PMRI) DI SMK AL KARAMAH
Abstract
Kemampuan komunikasi matematis diperlukan dalam memahami pelajaran yang diberikan oleh guru. Rendahnya kemampuan komunikasi matematis peserta didik SMK Al Karamah Jombang disebabkan karena peserta didik kurang diikutsertakan dalam pembelajaran atau peserta didik jarang diberikan kesempatan untuk bertanya maupun mengungkapakan pendapat. Pendekatan pembelajaran yang digunakan guru selama ini kurang tepat, sehingga kemampuan komunikasi matematis peserta didik belum mampu tersampaikan. Salah satu model pembelajaran yang cocok adalah pendekatan Pendidikan Matematika Realistik Indonesia (PMRI) untuk melihat apakah terdapat perbedaan pembelajaran tersebut dengan model pembelajaran konvensional terhadap peningkatan kemampuan komunikasi matematis ditinjau dari jenis kelamin peserta didik.
Jenis eksperimen yang digunakan dalam penelitian ini adalah Quasi Eksperimen Design menggunakan pretes dan postes. Populasi penelitian ini adalah peserta didik kelas XII SMK Al Karamah Jombang. Sampel yang digunakan sebanyak 1 kelas yang dipilih dengan teknik acak kelas, yaitu kelas XII SMK Al Karamah Jombang dengan pendekatan Pendidikan Matematika Realistik Indonesia (PMRI). Teknik pengumpulan data yang digunakan adalah tes. Analisis data yang digunakan adalah uji Kruskal-Wallis
Menurut hasil penelitian dan pembahasan, perhitungan dengan menggunakan uji Kruskal-Wallis, diperoleh nilai H = 1,233 < 7,815. Sehingga dapat diambil keputusan Ho dari hipotesis ini diterima, dengan kata lain bahwa Ha dari hipotesis yang diajukan ditolak maka dapat disimpulkan bahwa tidak terdapat perbedaan kemampuan komunikasi matematis yang menggunakan pendekatan pembelajaran Pendidikan Matematika Realistik Indonesia (PMRI) SMK Al Karamah Jombang Tahun Ajaran 2019/2020.

Open Data and Software Publishing and Sharing
The journal strives to maximize the replicability of the research published in it. Authors are thus required to share all data, code or protocols underlying the research reported in their articles. Exceptions are permitted but have to be justified in a written public statement accompanying the article.
Datasets and software should be deposited and permanently archived inappropriate, trusted, general, or domain-specific repositories (please consult http://service.re3data.org and/or software repositories such as GitHub, GitLab, Bioinformatics.org, or equivalent). The associated persistent identifiers (e.g. DOI, or others) of the dataset(s) must be included in the data or software resources section of the article. Reference(s) to datasets and software should also be included in the reference list of the article with DOIs (where available). Where no domain-specific data repository exists, authors should deposit their datasets in a general repository such as ZENODO, Dryad, Dataverse, or others.
Small data may also be published as data files or packages supplementary to a research article, however, the authors should prefer in all cases a deposition in data repositories.
