Abstract

Tujuan penelitian ini adalah (1) mengetahui apakah terdapat peningkatan hasil belajar kimia siswa kelas x dengan menggunakan model pembelajaran kooperatif tipe numbered head together (NHT). (2) mengetahui berapa besar peningkatan hasil belajar kimia siswa dengan menggunakan model pembelajaran numbered head together (NHT). Model pembelajaran kooperatif tipe numbered head together (NHT) merupakan variabel bebas sedangkan variabel terikatnya adalah hasil belajar siswa. Populasi dalam penelitian ini adalah seluruh siswa SMA N 114 Jakarta Utara yang dibagi dalam 2 kelas dengan total 60 siswa. Sampel dalam penelitian ini diambil dari dua kelas yaitu kelas X-MIA 1 sebagai kelas eksperimen dan kelas X-MIA 2 sebagai kelas kontrol. Teknik pengambilan sampel dilakukan dengan purposive sampling. Instrumem penelitian berupa tes soal. Uji prasyarat analisis menunjukan data terdistribusi normal dan bersifat homogen sehingga uji hipotesis statistik yang digunakan berupa uji parametrik. Uji hipotesis dilakukan pada taraf signifikan 0,05 dengan bantuan SPSS 22 for windows. Hasil penelitian ini memperoleh data pretest dan posttest kelas eksperimen dan kelas kontrol, dimana untuk kelas eksperimen diperoleh thitung sebesar 38.325 dan ttabel α/2 (df=29) maka ttabel = 2.045, maka untuk kelas eksperimen thitung (38.325) > ttabel (2.045) yang artinya Ha diterima (terdapat peningkatan hasil belajar kimia siswa dengan menggunakan model pembelajaran kooperatif tipe) numbered head together (NHT). Dari hasil uji gain diperoleh besar peningkatan hasil belajar dikelas eksperimen berada dalam kategori tinggi dengan rata-rata skor gain 0.78. Kata kunci : Hasil Belajar Kimia, Model Pembelajaran, Numbered Head Together (NHT). / The purpose of this research is (1) to know whether there is improvement of learning result of chemistry of class x student by using cooperative learning model numbered head together (NHT) type. (2) to know how much improvement of student's chemistry learning result by using model numbered head together (NHT). Cooperative learning model type numbered head together (NHT) is an independent variable while the dependent variable is the result of student learning. The population in this study is all students of SMA N 114 North Jakarta which is divided into 2 classes with a total of 60 students. The sample in this research is taken from two classes that is class X-MIA 1 as experiment class and class X-MIA 2 as control class. The sampling technique is done by purposive sampling. Instrumem research in the form of test questions. The prerequisite analysis test shows normal and homogeneous distributed data so that the statistical hypothesis test is used in the form of parametric test. Hypothesis test performed at significant level 0.05 with the help of SPSS 22 for windows. The results of this study obtained pretest and posttest data of experimental class and control class, where for the experimental class obtained tcount of 38.325 and ttable α / 2 (df = 29) then ttable = 2.045, then for experimental class tcount (38.325)> ttable (2.045 ) which means Ha is accepted (there is an increase in students' chemical learning outcomes using cooperative learning model type) numbered head together (NHT). From result of gain test obtained big increase study result class in experiment is in high category with average score gain 0,78. Keywords: Learning Outcomes Chemistry, Learning Model, Numbered Head Together (NHT)
