Penelitian ini bertujuan untuk mendeskripsikan tahap berpikir geometri siswa SMP menurut teori Van Hiele ditinjau dari keterampilan geometri. Jenis penelitian adalah deskriptif menggunakan pendekatan kualitatif. Sampel penelitian adalah sembilan siswa kelas VIII dari tiga SMP Negeri Kota Sampit yang dipilih menggunakan teknik stratified proportional random sampling dan dilanjutkan dengan purposive sampling. Data penelitian dikumpulkan melalui wawancara mendalam terhadap subyek setelah diberikan tes keterampilan geometri. Teknik analisis data yang digunakan adalah kualitatif secara interaktif maju berkelanjutan di antara pengumpulan data, reduksi data, penyajian data, triangulasi data, dan penarikan kesimpulan. Hasil penelitian mengungkapkan bahwa: (1) keterampilan geometri siswa beragam pada tiap …

This longitudinal study examined the relationship between executive function (EF) and mathematics with rural and urban preschool children. A panel of direct and indirect EF measures were used to compare how well individual measures, as well as analytic approaches, predicted both numeracy and geometry skill. One hundred eighteen children, ages 39 to 68 months, were given EF and mathematics assessments twice, approximately six months apart, concurrent to their teachers completing an indirect assessment of EF for each child. Results suggest: (1) the child’s age determines if a panel of direct EF measures is a better predictor of numeracy and geometry …
