PENERAPAN MODEL PEMBELAJARAN GUIDED DISCOVERY UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS SISWA KELAS XI SMA N 9 PEKANBARU DALAM PEMBELAJARAN FISIKA

Abstract

Abstract: This research aimed to know enhancement on critical thinking skills
secondary grades students SMA N 9 Pekanbaru through application guided
discovery learning model in learning physics and to know the difference learning
outcomes between secondary grades students that teached by conventional learning
model with secondary grades students that teached by guided discovery learning
model on spring force matter. This research conducted on SMA N 9 Pekanbaru from
July to December 2015. This type of research is quasi experimental design with
Nonequivalent Control Group Design. Sampling technique of this research used
simple random sampling technic by taking two classes at random from population.
The Samples is sciences two as experiment class and sciences four as control class.
The number of students on experiment class is 29 childrens which consist of 10 boys
and 19 girls.While the number of students on the control class of 30 people consist of
12 boys and 18 girls.Multiple choices questions used for collect data as technique
test. Based on analyze of mean percentage posttest show that mean percentage
experiment class with 71,67 % percentages is different than control class with
59,52 % percentages. Based on analyze with t-test, show that thitung > ttabel then Ho
rejected and Ha accepted with a significance level 5 %. Its show that there are
difference learning outcomes between experiment class and control class.

Keywords: critical thinking skills, guided discovery learning, conventional learning,
spring forces.
