Abstract

AbstractThis study aims at investigating the effect of youtube tutorial on mental computation flexibility among pre-service teachers. Mental computation might be vied as a relatively new term among students and teachers. Therefore, to introduce it to them need various methods and approaches. This study provided extra online material posted in youtube as a learning resource for pre-service primary teachers. The method used in this study was the pre-experimental research with the type of one-group pretest-posttest design. The population of this study was Indonesian pre-service teachers and the sample was chosen by technique of purposive sampling. The sample was from four universities in Indonesian, three public universities and one private university. The data were collected and analyzed both quantitatively and qualitatively. The quantitative approaches used this study were wilcoxon test and  N-gain value. The result of the study showed that youtube tutorials have a significance impact on the improvement pre-service teachers’ competency of mental computation.

Abstract

Kemampuan representasi siswa masih tergolong rendah, sehingga diperlukan suatu model pembelajaran yang mampu mempengaruhi kemampuan representasi matematis siswa, yaitu model pembelajaran Discovery Learning. Subjek penelitian ini adalah siswa kelas VII-11 MTsN 1 Banda Aceh yang berjumlah 37 orang. Jenis penelitian ini merupakan penelitian deskriptif kuantitatif. Adapun rancangan penelitian yang digunakan adalah One-Shot Case Studi. Instrumen yang digunakan untuk proses pengumpulan data adalah hasil tes kemampuan representasi matematis siswa, lembar observasi kemampuan guru mengajar, lembar observasi aktivitas siswa, dan angket respon siswa. Data yang diperoleh diolah dengan menggunakan persentase dan deskripsi skor rata-rata sehingga diperoleh informasi tentang tes kemampuan representasi matematis siswa, kemampuan guru mengajar, aktivitas siswa, dan respon siswa. Hasil penelitian menunjukkan bahwa pembelajaran dengan model Discovery Learning efektif untuk meningkatkan kemampuan representasi matematis siswa. Hal ini dikarenakan, (1) hasil tes kemampuan representasi matematis siswa tinggi, 2) kemampuan guru mengajar berada pada kategori baik atau sangat baik, (3) aktivitas siswa aktif, dan (4) respon siswa terhadap pembelajaran positif.
