The Comparison between Predict Observe Explain (POE) and Think Pair Share (TPS) Learning Model on Students Learning Achievement, Activity, and Critical Thinking Skill on Human Circulatory System

This research aims to investigate the comparison of
student learning achievement, critical thinking skill and activity
between Predict Observe Explain and Think Pair Share learning
model on the topic human circulatory system. This study was a
quasi experimental research with equivalent post test control
group design. The population of this study was 184 eleventh
grade students of SMA Negeri 2 Balige. There were 2 classes
chosen as the sample by applying cluster random sampling
technique. One class was taught by Predict-Observe-Explain
(POE) model while another one class was taught by TPS (Think
Pair Share) model. Instruments test used consist of cognitive test
in the multiple choice and essay test, critical thinking test in the
essay form and observation sheet for activity. Based on data
analysis, the average value of posttest in POE group higher than
TPS group. While based on t-test analysis, there was no a
significant difference of student learning achievement between
POE with TPS learning model. Then, there was significant
difference of students critical thinking skill that taught by POE
learning model. The observation results show that student
activity in both research classes is significantly different. The
students in POE class were more active than students in TPS
class. That means students activity in POE class is higher than
students activity in TPS class
