THE DIFFERENCE OF STUDENT’S LEARNING OUTCOME U S I N G I N Q U I R Y B A S E D L E A R N I N G A N D D I R E C T INSTRUCTION MODEL IN DYNAMIC ELECTRICITYAT GRADE X SMA N 11 MEDAN A.Y 2015/2016

This research had been doing at grade X SMA Negeri 11 Medan academic
year 2015/2016. The purpose of this research was to find out the average mark of
student learning outcomes of using Inquiry Based Learning Model and Direct
Instruction Model in dynamic electricity and to find out the significan difference
of student’s learning outcomes using inquiry based learning model and direct
instructional model in dynamic electricity. The research method was quasi
experimental. The population were all students at X class consist of 10 classes.
The sample of this research conduct two classes and consist of 40 students, here
class X3 as experiment class and class X5 as control class and define by random
cluster sampling. The results that were obtained: post-test mean value of the
experimental class was 63.92 and 53.30 was the mean value for control class.
Standard deviation for two classes were 8.72 and 12.43. Normality test result from
the both samples was normal and homogenous, the testing criterion was accept H0
if -2.024< t’ <2.024 and refuse Ho in other condition. Here, H0 was refused
because t’ is 3.130 and Ha was accepted. So it can be concluded that there was
significant difference of student’s learning outcomes using inquiry based learning
model and direct instructional model in dynamic electricity
