This Classroom Action Research (CAR) aims to increase motivation and interest in learning mathematics in class XI IPS 3 of SMA Negeri 2 Merauke by using a variety of learning media. The subjects in this study were 30 students of class XI IPS 3, 17 male students and 13 female students. The cycleof CAR uses the Kemmis & Mc Taggart model with stages of planning, implementation, observation, and observation. Pre-cycle data shows that students' motivation and interest in learning mathematics are in the low category. The study was conducted in 2 cycles with 4 meeting for each cycles. Based on the results of student observation activities indicate that student activities have increased in learning process of cycle I and cycle II. The average percentage of student learning activity in the first cycle reached 57%, and increased in the second cycle, amount 83%. Increased percentage of student’s learning activity in cycle I and cycle II by 26%. Student learning motivation in the good category experienced an increase from pre-cycle with a percentage of 37.16%, 62.72% in the first cycle, and 90.12% in the second cycle. Student’s interest in the good category also increased from pre-cycle with a percentage of 35.34%, in the first cycle 58.55%, and in the second cycle increased to 93.55%. Based on the results of this study it can be concluded that by using a variety of learning media can increase motivation and interest in learning mathematics in class XI IPS 3 of SMA Negeri 2 Merauke. With the motivation and interest in learning students towards mathematics, it is expected that students themselves will be able to more easily understand mathematics and mathematics no longer be a frightening subject for students. Keywords: variations in learning media, motivation, interests.
Tujuan dilaksanakannya penelitian ini adalah mengetahui peningkatan kemandirian belajar mahasiswa melaui implementasi blended learning. Subjek dalam penelitian ini adalah mahasiswa Jurusan Pendidikan Matematika Universitas Musamus yang mengambil mata kuliah persamaan diferensial sebanyak 32 mahasiswa. Penelitian tindakan kelas ini menggunakan siklus penelitian Tindakan kelas Kemmis & Mc Taggart yang dilakukan sebanyak 2 siklus. Teknik pengumpulan data yang digunakan berupa dokumentasi dan observasi. Berdasarkan analisis data yang diperoleh, implementasi blended learning mampu meningkatkan kemandirian mahasiswa terbukti dari hasil yang diperoleh terjadi peningkatan jumlah mahasiswa yang memiliki kemandirian belajar. Data kemandirian belajar pra siklus menunjukkan bahwa sebesar 21,35% mahasiswa memiliki aspek kemandirian belajar, setelah implementasi blended learning didapat hasil pada siklus 1 meningkat menjadi 49,38% mahasiswa, dan mengkat lagi pada siklus 2 menjadi 78,75% mahasiswa. Dengan implementasi blended learning juga mampu meningkatkan prestasi belajar mahasiswa yang ditunjukan dari data prestasi mahasiswa. Pada siklus 1, jumlah mahasiswa yang lulus sebesar 46,88%, dan meningkat pada implementasi siklus 2 menjadi 71,88%.
Penelitian ini merupakan penelitian eksperimen dengan menggunakan desain one group pretest-posttest design. Tujuan penelitian adalah untuk mengetahui pengaruh penggunaan Software Geogebra pada proses pembelajaran terhadap kemampuan pemecahan masalah siswa kelas VIII. Subjek penelitian ini adalah siswa kelas VIII B SMP Negeri 2 Merauke yang berjumlah 25 orang. Teknik sampling yang digunakan menggunakan cluster random sampling. Materi pelajaran yang diberikan adalah materi pelajaran pada semester ganjil yaitu persamaan garis lurus. Hasil penelitian diperoleh bahwa kemampuan pemecahan masalah matematika siswa kelas VIII SMP Negeri 2 Merauke sesudah penggunaan software geogebra lebih baik dari sebelum penggunaan software geogebra. Pengaruh tersebut ditunjukkan dari perolehan rata-rata nilai pretest lebih tinggi dari rata-rata nilai posttest, dengan peningkatan prestasi belajar matematika siswa berada pada kategori “sedang” yaitu 0,534. Dengan demikian, terdapat pengaruh kemampuan pemecahan masalah matematika siswa kelas VIII B SMP Negeri 2 Merauke setelah dilakukan pembelajaran menggunakan software geogebra
This research aims to describe students' errors based on the Newman procedure in solving narrative questions on whole number reviewed from cognitive style and its causing factors. This was a descriptive qualitative research with the students of fourth grade of SD Negeri 1 Merauke of 2017/2018 served as the subject of the research. The data collection techniques used were subjective tests, interviews and documentation. Data analysis was done by data reduction, data presentation, and conclusion drawing. Based on the results of the research, students with FD cognitive style made reading error, comprehension error, transformation error, process skill error and encoding error. While the FI student made a mistake in the form of process skill error and encoding error. The causes of errors experienced by students include confusion regarding the completion steps, lack of mastery of the material, limited time to work, and not being accustomed to writing the final answer or drawing conclusions.
