PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE STUDENT TEAM ACHIEVEMENT DIVISIONS (STAD) UNTUK MENINGKATKAN HASIL BELAJAR MATEMATIKA SISWA PADA MATERI LINGKARAN DI KELAS VIII MTS S MIFTAHUSSALAM MEDAN TAHUN PELAJARAN 2015/2016
Abstract: The problem in this
study is less the maximum result of students' mathematics learning in class
VIII-3 MTs Miftahussalam Medan. Thisis evident from the test results
pre-action, observation and interviewresearchers who demonstrate a lack of
understanding of the students to learn math so that the necessary efforts and
modeles teachers use learning modeles. This study aims to increase the
students' mathematics learning in class VIII-3 MTs Miftahussalam Medan using
cooperative learning model Student Team Achievement Divisions (STAD). This classroom
action research conducted through two cycles that includesplanning,
implementation, observation and reflection. To know the results of students'
mathematics learning, the researchers used the test results to learn math
student individually. That is the subject of this research is class VIII-3 MTs
Miftahussalam Terrain totaling 40 students consisting of 19 male students and
21 female students. Before administering the actions, the percentage of
classical completeness of the test scores of students seen pre-action on
previous material still relevant and classical completeness of students
obtained 15% (6 students) with an average of 25.625. After administering the
act of teaching through cooperative learning model Student Team Achievement
Divisions (STAD), the test results of students' mathematics learning in the
first cycle, the percentage of classical completeness acquired 60.00% (24
students) with an average of 65.125.Meanwhile, after repairs from the first
cycle to the second cycle, the test math achievement test in the second cycle,
the percentage of classical completeness acquired 87.50% (35 students) with an
average grade 79.625. So from the condition before being given corrective
action until the cycle is obtained an increase of 72.5%. From the results of
this class action, the researchers concluded their mathematics learning outcome
of students with cooperative learning model Student Team Achievement Divisions
(STAD) in the class VIII-3 MTs Miftahussalam Medan.
