PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER (NHT) TERHADAP HASIL BELAJAR BIOLOGI PADA MATERI SISTEM REGULASI
Abstract: This study aims to
determine: (1) The results of studying biology at the material regulatory
system students taught by cooperative learning model NHT, (2) Results of
studying biology at the material regulatory system students who are taught by
the model of expository, and (3) Effect models NHT cooperative learning for
learning outcomes on material regulatory systems biology class XI IPA at SMAN
11 Medan TP 2015/2016. Research was conducted on students of class XI IPA at
SMAN 11 Medan T.P. 2015/2016. The study population was all students of class XI
of five classes (200 people). The sampling technique used by cluster random
sampling, so this study sample consisted of two classes each class consists of
40 people. Class experiment with applying cooperative learning model Numbered
Heads Together (NHT) and grade control with the application of expository. The
findings show: (1) The results of studying biology at the material regulatory
system students taught by cooperative learning model NHT has an average value
of 81.03 by the tendency of learning outcomes 80% in the high category, (2)
Results of studying biology at material regulatory system that taught students
with expository teaching model has an average value of 71.40 by the tendency of
learning outcomes 72.50% in enough categories, and (3) the influence of
cooperative learning model NHT to the learning outcomes on the material systems
biology regulation of class XI IPA at SMAN 11 Medan TP 2015/2016. This result
is based on the calculation of the difference test average value posttest
experimental class and control class obtained that thitung> ttable ie t =
9.22> t table = 1.667.
