In a family, the presence of parents is very important for the development of a child's personality, because the family is the first and foremost environment that will influence several aspects of child development, including the child's polite attitude. But not all children have complete parents, there are some children who are so unlucky that they only have one parent. But how to educate single parents is not much different from parents who are intact in instilling child courtesy. The cultivation of polite attitudes given by single parents to children is to provide understanding of what is good and bad and to give good examples to their children, so that children are more accustomed to seeing good things and can be imitated by children in everyday life. In this article, we will describe the polite behavior of children seen from the parenting styles applied...

Tujuan penelitian ini adalah untuk menganalisis kemampuan pemecahan masalah matematis siswa ditinjau dari gaya kognitif reflektif dan impulsif. Penelitian ini menggunakan metode pendekatan kualitatif deskriptif. Penelitian ini dilakukan pada kelas 7 di sebuah SMP Negeri di Kudus, Jawa Tengah. Subjek yang diambil yaitu 8 siswa dengan dua siswa bergaya kognitif reflektif, dua siswa bergaya kognitif impulsif, dua siswa bergaya kognitif slow inaccurate, dan dua siswa bergaya kognitif fast accurate. Teknik pengumpulan data yang digunakan adalah tes Matching Familiar Figure Test (MFFT), tes kemampuan pemecahan masalah matematis siswa, dan wawancara. Analisis data yang digunakan adalah reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian yang sudah dilakukan menunjukkan bahwa siswa dengan gaya kognitif reflektif dan fast accurate mampu memenuhi semua indikator kemampuan pemecahan masalah yaitu (memahami masalah, merencanakan masalah, menyelesaikan masalah dan memeriksa kembali) dalam menjawab soal cerita. Siswa dengan gaya kognitif impulsif dan slow inaccurate hanya memenuhi 2 indikator kemampuan pemecahan masalah (memahami masalah dan merencanakan masalah), sedangkan untuk indikator menyelesaikan masalah dan memeriksa kembali subjek tidak dapat menyelesaikan dengan baik dan tidak dapat memberikan kesimpulan yang benar.

Ketidaksenangan tersebut akan memunculkan rasa takut dan cemas ketika belajar matematika. Kecemasan matematika juga dapat muncul karena proses pembelajaran matematika yang kurang menyenangkan. Tujuan penelitian ini yaitu: (1) mengetahui apakah rata-rata kecemasan matematika peserta didik yang diajar dengan pembelajaran probing-prompting bernuansa etnomatematika lebih rendah dari rata-rata kecemasan matematika peserta didik yang diajar dengan pembelajaran ekspositori dan (2) mengetahui penurunan kecemasan matematika peserta didik yang mengikuti pembelajaran probing-prompting bernuansa etnomatematika. Penelitian ini mengacu pada nonequivalent control group design yang merupakan bentuk desain dari kuasi eksperimen. Penelitian ini dilakukan di kelas IV SD NU Nawa Kartika Kudus pada semester genap tahun pelajaran 2016/2017. Teknik pengumpulan data yang digunakan yaitu dengan pemberian angket untuk mengukur kecemasan matematika peserta didik. Teknik analisis data dalam penelitian ini meliputi uji perbedaan rata-rata (uji t) dan uji gain untuk mengetahui penurunan kecemasan matematika peserta didik. Hasil penelitian menunjukkan bahwa rata-rata kecemasan matematika peserta didik yang diajar dengan pembelajaran probing-prompting bernuansa etnomatematika lebih rendah dari rata-rata kecemasan matematika peserta didik yang diajar dengan pembelajaran ekspositori dan kecemasan matematika peserta didik yang mengikuti pembelajaran probing-prompting bernuansa etnomatematika mengalami penurunan sebesar 48% dengan kategori sedang.
