Muhammadiyah 4 Kebomas yang terdiri dari dua kelas yaitu kelas VII A yang terdiri dari 30
peserta didik dan kelas VII B yang terdiri dari 29 peserta didik. instrumen penelitian yang
digunakan yaitu tes kemampuan pemecahan masalah matematika berbentuk soal uraian.
Berdasarkan analisis data menggunakan uji t dua sampel independen (Independent Sample t
Test) diperoleh nilai sig = 0,033 < 0,05 , maka H0 ditolak sehingga dapat disimpulkan nilai
posttest kelas eksperimen lebih besar dari pada nilai posttest kelas kontrol, artinya ada pengaruh

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.
