Abstract:
This research aims to improve mathematics learning outcomes VIII
a
grade students at SMP N 2 Cerenti second semester of academic year 2011/2012
to implement cooperative learning model two stay two stray. This study is a class
action consisting of two cycles. Data collected in this study is a teacher and
student activity data and student learning outcomes data. Teacher andstudent
activity data collected through observation techniques using observation sheets,
while the student learning outcomes data gathered through the test (repeat daily)
use problems. Results showed that the teacher in the learning activities are more
appropriate to the lesson plan, as well as with student activities that can be seen
from the first cycle is the percentage of students who achieve KKM 15% of the 20
students, then increased in the second cycle with 70% percentage of completeness,
when seen from the results of learning, there is a decrease in the first cycle, the
percentage of students at mastery base score is 55%, then on the second cycle
after the given measure student mastery percentage increased to 70%. So it can be
concluded that by implementing cooperative learning model TSTS can improve
student learning outcomes.
