Abstract
Blended learning is a learning method that combines two or more learning method. The objective of this research is to know the improvement of mathematical reasoning ability of student of mathematics prospective teacher, through Blended Learning with Probing-prompting learning strategy. The research method used is quantitative research, and divides participants into two groups. The first group is the experimental class group, it is the group of prospective teachers who get Blended Learning with Probing-Prompting Strategy and the second group is the control group; which is prospective teachers who get conventional learning. The study was conducted on 6th semester prospective teacher students from one university in Bandung, West Java, Indonesia. Based on this research, it is known that: experimental class group; which is the group of prospective teachers who get Blended Learning has improved the ability of mathematical reasoning is better than the control class group. It can be seen from the results of the normalized gain calculation of the experimental class reaches an average of 0.50 while the normalized gain of the control class reaches an average of 0.34. Although both are still in medium category, but based on t-test results between two parties, found that the increase has significant differences.
Highlights
PENDAHULUAN Penalaran dalam matematika merupakan sesuatu yang pokok dan penting, tidak pernah sedikitpun penalaran lepas dari matematika, sehingga dapat dikatakan bahwa penalaran adalah intinya matematika
The objective of this research is to know the improvement of mathematical reasoning ability of student of mathematics prospective teacher, through Blended Learning with Probing-prompting learning strategy
The first group is the experimental class group, it is the group of prospective teachers who get Blended Learning with Probing-Prompting Strategy and the second group is the control group; which is prospective teachers who get conventional learning
Summary
Instrumen penelitian yang disusun terdiri dari: (1) tes kemampuan awal mahasiswa dan tes kemampuan penalaran matematis; (2) angket untuk mengukur kemampuan penalaran mahasiswa;(3) lembar observasi untuk mencatat aktivitas dosen dan mahasiswa ketika pembelajaran; (4) panduan wawancara untuk mengetahui kesulitan mahasiswa yang tidak dapat diketahui dari lembar jawaban mahasiswa. Sedangkan sampel dalam penelitian ini adalah 80 orang mahasiswa yang dipilih secara acak kelas. Teknik pengumpulan data yang digunakan dalam penelitian ini meliputi teknik pengumpulan data kuantitatif dan kualitatif. Pengumpulan data kuantitatif dan kualitatif dilakukan pada waktu yang bersamaan dan bergantian dalam selang waktu yang tidak terlalu lama. Untuk mengukur keberhasilan pembelajaran, kepada subjek penelitian diberikan dua kali tes kemampuan yang sama, yaitu dia awal (pretest) dan di akhir semester (posttest). Data kuantitatif diperoleh dari analisis pretest dan posttest, sedangkan data kualitatif diperoleh dari analisis lembar observasi, wawancara, angket, serta catatan lapangan dan dokumentasi. Peralatan yang digunakan dalam penelitian ini tidak ada yang khusus, hanya berupa koneksi internet untuk kelas Blended Learning Probing-prompting (BLPP). HASIL DAN PEMBAHASAN Analisis data yang dilakukan terhadap hasil penelitian ini adalah analisis terhadap data hasil tes awal, tes akhir, dan skala sikap. Analisis data tes awal pada kelompok eksperimen dan kelompok kontrol dapat dilihat pada Tabel 1 berikut: Tabel 1 Nilai Maksimum, Nilai Minimum, Rata-rata dan Simpangan Baku
