This study aimed to determine student learning outcomes using the Synectic learning model and learning outcomes using conventional learning models at YAPIM Taruna Dolok Masihul Private High School. The population was all students of class XII SMA which consisted of 2 classes. Samples were taken randomly from 2 classes consisting of the experimental class and the control class. The data observed were chemistry students' learning outcomes, which were collected through a multiple choice test of 20 questions consisting of 5 answer options, which had been tested for validity, reliability, difficulty level and test differentiation. The data obtained were analyzed using the T test, which previously tested the normality and homogeneity of the data. The learning outcomes of the experimental class mean pre-test (27.81 ± 7.21) and post-test mean (76.88 ± 5.70) with an increase in learning outcomes Gain by 68%, while the learning outcomes of the control class average pre-test (22.03 ± 6.70) and the average post-test (70.47 ± 6.00) with an increase in learning outcomes gain by 62%. Hypothesis testing is carried out at the significance level α = 0.05 using one-sided t-test, namely the right side where tcount> ttable (3.05> 1.667139), which means that Ho is rejected and Ha is accepted. By looking at the results of these studies it can be concluded that the chemistry learning outcomes of students who were treated through the application of the Synectic learning model are higher than using conventional teaching.

Permasalahan dalam penelitian ini adalah rendahnya aktivitas dan hasil belajar ekonomi siswa. Tujuan dan penelitian ini adalah untuk mengetahui peningkatan aktivitas dan hasil belajar ekonomi siswa kelas X SMA Negeri 1 Kualuh Hulu dengan penerapan model pembelajaran ARIAS (Assurance, Relevance, Interest, Assessment, and Satisfaction). Teknik pengumpulan data menggunakan tes dan observasi. Tes yang digunakan adalah pilihan berganda diberikan secara individual yang dilaksanakan di setiap akhir siklus. Hasil belajar pada sikius I diperoleh persentase ketuntasan secara klasikal adalah 55%. Pada siklus II persentase ketuntasan secara klasikal sebesar 85% menunjukan terjadi peningkatan ketuntasan secara kiasikal sebesar 30%. Hasil ratarata aktivitas belajar siswa pada siklus I sebanyak 4 orang (10%) siswa untuk kurang aktif, 22 orang (55%) siswa cukup aktif, 6 orang (15%) siswa aktif, 8 orang (20) siswa sangat aktif. Sedangkan Sildus II mengalami peningkatan menjadi 2 orang (5%) siswa cukup aktif, 23 orang ( 57,5%) siswa aktif, 15 siswa (37,5%) siswa sangat aktif, menunjukkan terjadi peningkatan aktivitas hasil belajar 60%. Hal ini menunjukkan bahwa pada siklus II telah diperoleh ketuntasan aktivitas dan hasil belajar ekonomi siswa yang ditunjukkan dengan peningkatan yang signifikan. Berdasarkan uraian diatas disimpulkan bahwa penerapan model pembelajaran ARIAS dapat meningkatkan aktivitas dan hasil belajar ekonomi siswa di kelas X SMA Negeri 1 Kualuh Hulu Tahun Ajaran 2011/2012.

Pembelajaran Matematika di sekolah membutuhkan penggunaan model oleh guru Matematika di Sekolah Dasar. Guru matematika harus terlebih dahulu mengetahui model pembelajaran yang tepat di sekolah dalam proses belajar mengajar. Adanya penggunaan model pembelajaran kooperatif tipe snowball throwing. Guru memegang andil penting supaya proses belajar mengajar menyenangkan, mampu menarik siswa dan aktif sehingga tujuan pembelajaran tercapai. Kata Kunci: Pendidikan, Peserta didik, Guru
