THE EFFECT OF GUIDED DISCOVERY LEARNING MODEL TO STUDENTS LEARNINGACHIEVEMENT IN STATIC FLUID TOPIC AT CLASS X1 SMA N 1 SERDANG BEDAGAI ACADEMIC YEAR 2015/2016

The objectives of this research are: (1) to know the student’s learning
outcomes in physics subject after taught by Guided Discovery Learning Model,
(2) to know the student’s learning achievement in physics subject after taught by
Conventional Learning, (3) to know the effect of Guided Discovery Learning
Model on student’s learning achievement of Static Fluid in Class XI SMA N 1
Serdang Bedagai Academic Year 2015/2016. The research method was quasi
experimental. The research subject were populations were all XI IPA semester II
SMA N 1 Serdang Bedagai that consist of 2 classes. Each class consist 25
students, XIIPA2 as experiment class, XIIPA1 as control class.
From data analyze results were obtained: pre-test mean value of
experiment class was 21.19 and 18.68 for control class and then post-test mean
value of the experiment class was 64.96 and 56.52 was the mean value for control
class. Standard deviation in pre-test was 3.02 in experiment class and 2.97 in
control class and standard deviation in post-test for two classes were 8.59 and
7.54. Both samples was normal distribution and homogenous. Hypothesis test for
post-test using t-test one side, the criteria is : Ha is accepted if tcount > ttable and is
rejected if tcount has another score. From the calculation of t-test one side obtained
tcount = 3.89, where ttable = 2.012, tcount > ttable. So, there is effect of Guided
Discovery Learning Model on Student’s Learning achievement in Static Fluid in
Class XI SMA N 1 Serdang Bedagai.
Linear equation has a value that increases slope. If seen from the graph,
the value of a at ypost=0.833x+54.05 bigger than the value of a at
ypre=0.405x+15.85. However, from the graph it appears that the value apost > apre,
which indicates that the activity is affect the value of learning outcomes
