标题：EFEKTIVITAS PEMBELAJARAN DBL BERBASIS IDENTIFIKASI DAN ANALISIS KEBUTUHAN ALAT PERAGA DI KELAS VIII TERHADAP KEMAMPUAN PENALARAN PADA MATERI GEOMETRI
摘要：Penelitian ini bertujuan untuk mengetahui: (1) rata-rata kemampuan penalaran perta didik kelas VIII menggunakan model DBL dengan alat peraga manipulatif mencapai KKM;(2) rata-rata kemampuan penalaran peserta didik kelas VIII menggunakan model DBL dengan alat peraga manipulatif lebih baik daripada model ekspositori pada materi limas.Populasi penelitian ini adalah seluruh peserta didik kelas VIII SMP Negeri 22 Semarang tahun pelajaran 2014⁄2015.Dengan teknik cluster random sampling,terpilih sampel yaitu peserta didik kelas VIII A sebagai kelas eksperimen dan kelas VIII D sebagai kelas kontrol.Metode pengumpulan data meliputi: observasi,tes dan dokumentasi.Analisis data yang digunakan adalah uji normalitas,uji homogenitas,uji prporsi dan uji beda ratarata.Hasil penelitian menunjukkan bahwa: (1) rata-rata kemampuan penalaran peserta didik kelas VIII menggunakan model DBL dengan alat peraga manipulatif mencapai KKM;(2) rata-rata kemampuan penalaran peserta didik kelas VIII menggunakan model DBL dengan alat peraga manipulatif lebih baik model ekspositori.
其他摘要：This study have two purposes namely they were to determine: (1) the average of mathematical reasoning ability of the eighth grade students used DBL model based on manipulative teaching aids achieved the minimum passing grade criteria,(2) the average of mathematical reasoning ability of the eighth grade students used DBL model based on manipulative teaching aids was better than in the expository model.The population of this research was the eighth grade students of State Junior High School 22 Semarang in academic year 2014/2015.The sampling technique that was used was cluster random sampling technique,the samples that were chosen were class VIII A as an experimental class and VIII D as a control class.The research methods that were used were observation,test method,and documentation.The data analysis that was used was normality test,homogenity test,proportional test,and mean differential test.The result of this research showed that: (1) the average of mathematical reasoning ability of the eighth grade students used DBL model using manipulative teaching aids achieved the minimum passing grade criteria,(2) the average of mathematical reasoning ability of the eighth grade students used DBL model.using manipulative teaching aids was better than the average of mathematical reasoning ability of the students in the expository model.
