Abstract

Latar belakang masalah dalam penelitian ini adalah keabstrakan matematika yang menyebabkan rendahnya disposisi dalam belajar matematika siswa kelas VIII 1 SMP Negeri 1 Marancar. Keabstrakan ini menyulitkan siswa dalam menyelesaikan masalah matematika sehingga siswa membutuhkan adanya perantara atau media agar materi pelajaran tampak konkrit bagi siswa. Disamping itu dengan penggunaan media powerpoint ini diharapkan dapatmemotivasi siswa agar lebih semangat dan terus belajar. Dalam hal ini adalah tentang penggunaan media powerpoint di SMP Negeri 1Marancar. Penelitian ini bertujuan untuk menganalisis kemampuan disposisi matematis siswa melalui pembelajaran media powerpoint dikelas VIII-1 SMP N.1 Marancar. Penelitian ini merupakan penelitian kualitatif, dengan informan penelitian adalah kelas VIII-1 SMP Negeri 1 Marancar dengan jumlah siswa 21 orang. Kemudian instrumen yang digunakan dalam pengumpulan data ini adalah wawancara dengan siswa dan juga angket. Dalam pelaksanaan penelitian dilakukan sebanyak 2 kali pertemuan. Dari hasil penelitian tersebut didapati angket kemampuan disposisi matematis siswa yang mencapai 80,6 dan angket reson siswa terhadap pelajaran media powerpoint dengan kriteria layak pakai dengan perolehan 76,90%.

Abstract

Penelitian ini bertujuan untuk mengetahui keefektifan model learning cycle 5E terhadap kemampuan komunikasi matematis siswa di SMP Negeri 9 Padangsidimpuan. Jenis penelitian ini adalah penelitian eksperimen dengan design one group pretest posttest. Sampel diperoleh sebanyak 30 siswa yang diambil dengan menggunakan teknik cluster random sampling. Pengumpulan data menggunakan observasi dan tes kemampuan komunikasi yang sebelumnya sudah divalidasi. Analisis data yang digunakan adalah analisis deskriptif dan statistik inferensial. Berdasarkan analisis deskriptif, nilai rata-rata penerapan model learning cycle 5E terhadap kemampuan komunikasi matematis siswa adalah 3,92 (kategori sangat baik), rata-rata kemampuan komunikasi matematis siswa pada materi SPLDV (Sistem Persamaa Linier Dua Variable) sebelum menggunakan model learning cycle 5E adalah 67,05 (kategori cukup) dan setelah menggunakan model learning cycle 5E adalah 79.94 (kategori sedang). Selanjutnya, berdasarkan statistik inferensial dengan menggunakan paired sample test (SPSS 22) diperoleh nilai signifikannya sebesar 0,000 < 0,05, sehingga hipotesis alternatif dalam penelitian ini dapat diterima kebenarannya. Artinya, terdapat pengaruh yang signifikan antara penggunaan model learning cycle 5E terhadap kemampuan komunikasi matematis siswa di SMP Negeri 9 Padangsidimpuan di mana nilai indeks N-gain adalah 0,56 (kategori sedang).

Abstract

Problem solving ability is the most basic ability in mathematics that teacher must train students. Different learning motivation among student can affect students’ ability to solve problems. This study aims to desribe students’ problem solving abilities according to the levels of learning motivation (1) High, (2) Medium (3) Low. The subjects in this study were 24 students of seventh grade students of SMP Negeri 5 Padangsidimpuan. The method uses descriptive qualitative. Data collection techniques use questionnaires, tests, and interviews. The results shows that haigh learning motivation students have problem-solving skills that tended to be good, students are able to fulfill the four problem-solving indicators according to Polya, namely (1) understanding the problem, (2) making plans, (3) carryng out plans, (4) checking back. Medium learning motivation students have medium problem-solving abilities students are able to fulfill two or three indicators, (1) understanding the problem, (2) making plans, (3) some students have problems implementing plans for completion but some of them are able to carry out plans. Low learning motivation students are able to fulfill two indicators, (1) understanding the problem, (2) unable to determine which settlement plan to choose.
