THE EFFECT OF GUIDED DISCOVERY LEARNING MODEL ON THE STUDENT’S ACHIEVEMENT IN PHYSICS OF VII GRADE IN SMP N 1 TEBING TINGGI ACADEMIC YEAR 2013/2014

ABSTRACT: The  objective  of  this  research  is  to  know  the  effect  of  using Guided Discovery  learning  model on  the students’ achievement in  physics especially in temperature  topic  at  VII Grade  SMP N  1  Tebing  Tinggi. The research  method is  quasi  experiment.  The  populations are all of VII grade students in semester II that consist of 9 classes SMP N 1 Tebing Tinggi. The samples  of  this  research are two  classes  and  consist  of  70 students, 34 students from  experiment  class  and  36  students from  control  class  and define  by  random sampling. Data  shows  that pre test  mean  value  of experiment class is 42.06 and control class is 40.3. Post test mean value of experiment  class is 70 and  control  class is  65.28. The  data  distribution  of both sample are normal and homogenous. The criteria for hypothesis test is: H0 is  accepted  if -ttable < tcount <  ttable and  H0 is  rejected  if  tcount has  another score, where ttable obtained from list of t distribution. Research result shows that t-test for concept mastery using α = 0.05, obtained tcount = 0.507, where ttable = 1.99. It can be concluded that  the experiment class and control class have  same  ability. The  criteria for  post  test analysis is  :  Ha  is  accepted  if tcount > ttable and Ha is rejected if tcount has another score. Based on research data for α = 0.05, obtained tcount = 1.73, where ttable = 1.67. So, there is effect of Guided Discovery Learning Model  on the Student’s Achievement  in Temperature Topic at VII Grade in SMP N 1 Tebing Tinggi Academic Year 2013/2014. Based  on  observation using  observation  sheet  of  student activity, it can be concluded that the students in  experiment class are more active than control class.
