THE EFFECT OF COOPERATIVE LEARNING MODEL OF NUMBER HEAD TOGETHER (NHT) TYPE ASSISTED ANIMATION ON STUDENT’S LEARNING OUTCOMES OF X CLASS SMA 2 LINTONGNIHUTA A.Y. 2014/2015
ABSTRACT: Aims of study to
determine the effect of cooperative learning model of NHTtype to learning
outcomes of students in subject matter optical geometry inhigh school N 2
Lintongnihuta A.Y. 2014/2015.Kind of this research is quasiexperimental. The
population in this research were all students of class XSemester II SMA N 2
Lintongnihuta which consists of two classes. Samplingwas done by purposive
research by using two existing classes, namely classX Mia 2 were 26students as
experimental class and the class X Mia 1amounted to 30 students as the control
class. The instrument used is acognitive test in the form of multiple choice
question number 20 and observation sheet of student’s activity. Experimental
class was giventreatment by cooperative learning model of NHT type and grade
control with conventional learning.
Before being given different treatment performed pretest, which is theaverage
value of the experimental class pretest 48.65 with a standarddeviation 11.45
and the average value of the control class pretest 48.67 witha standard
deviation 14.07. Second class pretest data testing showed thatboth classes of
data were normally distributed and homogeneous. The testresults obtained
pretest tcount<ttable (0.0057 <2,14) then H0 is received, itmeans the
ability of students' initial experimental class and control class alike. Then
given treatment that is experimental class with cooperative learning model of
NHT type and grade control with conventional learning models. During
thelearning processinthe experimental classlearning activities of
studentsincreased, the meetingI59.79%, 72.07%meetingIIandIIImeeting
of75.30%.After the study was completed, given postest with an average 66.53 for
experimental class with a standarddeviation 11.64 and 48.66 with the control
class standard deviation 14.07.On testing normality and homogeneity of data
obtained postest that both classes of data were normally distributed and
homogeneous. The data processing postest obtained that tcount= 5.1 and ttable =
2.14, so that t count > t table (5.1> 2.14) then Hareceived means there
is influence of cooperative learning model of NHT type to students learning
outcomes in optic geometry material to X class SMA N 2 Lintongnihuta A.Y.
