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. This
is evident from the test results pre-action, observation and interview
researchers 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 includes
planning, 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.
