THE EFFECT OF GUIDED DISCOVERY LEARNING MODEL ON STUDENT’S ACHIEVEMENT AT CHARACTERISTICS OF WAVE TOPIC IN SMA N 1 MEDAN CLASS XI ACADEMIC YEAR 2014/2015
ABSTRACT: The aim of this
research was to find the effect of guided discovery learning model on student’s
achievement at characteristics of wave topic in SMA N 1Medan class XI academic
year 2014/2015. The research method was quasiexperiment. The populations were
all 2nd grade students odd semester consist of 13 classes in SMA N 1 Medan. The

results that were obtained: post-test mean value of the experiment class was
75.94 and 75.02 for control class. Standard deviation for two classes was 14.94
and 12.48. Normality of the test result from the both samples was normal and homogeneous.
So, there was the significant effect of using guided discoverylearning model.
It can conclude that studying with guided discovery learning model was higher
