REPRESENTASI MATEMATIS PESERTA DIDIK MENURUT PANDANGAN BRUNER DALAM MENYELESAIKAN SOAL GEOMETRI DITINJAU DARI KEMAMPUAN MATEMATIKA DAN JENIS KELAMIN
Abstract
Representasi matematis sangat dibutuhkan oleh peserta didik agar dapat dengan mudah
menyampaikan ide-ide dan gagasan dengan menginterpretasikan pemikiran terhadap suatu
masalah matematika. Dalam teori perkembangan kognitif, Bruner membedakan representasi
atas enactive, iconic dan symbolic. Representasi matematis dapat dilatih dan dikembangkan
melalui kebiasaan menyelesikan soal-soal geometri. Selain itu representasi matematis erat
kaitannya dengan kemampuan matematika dan jenis kelamin. Sehingga tujuan penelitian ini
adalah untuk mendeskripsikan representasi matematis peserta didik menurut pandangan Bruner
dalam menyelesaika soal geometri ditinjau dari kemampuan matematika (tinggi, sedang, dan
rendah) dan jenis kelamin (laki-laki dan perempuan) di SMPN 1 Duduk Sampeyan
Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek penelitian adalah 6
peserta didik kelas VIII-H SMPN 1 Duduk Sampeyan. Metode pengumpulan data yang
digunakan adalah metode tes dan wawancara. Instrument yang digunakan dalam penelitian ini
adalah tes kemampuan matematika, tes representasi matematis, dan pedoman wawancara.
Dari hasil analisis data, representasi matematis peserta didik laki-laki yang memiliki
kemampuan matematika tinggi dapat memenuhi ketiga indikator representasi matematis, peserta
didik laki-laki yang memiliki kemampuan matematika sedang dapat memenuhi ketiga indikator
representasi matematis, sedangkan peserta didik laki-laki yang memiliki kemampuan
matematika rendah hanya dapat memenuhi dua indikator representasi matematis. Representasi
matematis peserta didik perempuan yang memiliki kemampuan matematika tinggi dapat
memenuhi ketiga indikator representasi matematis, peserta didik perempuan yang memiliki
kemampuan matematika sedang dapat memenuhi dua indikator representasi matematis,
sedangkan peserta didik perempuan yang memiliki kemampuan matematika rendah tidak dapat
memenuhi ketiga indikator representasi matematis.

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.
