Peningkatan Kemampuan Pemecahan Masalah Prediksi Soal–soal Ujian Nasional Mata Pelajaran Matematika melalui Pendekatan Jigsaw pada Peserta Didik Kelas IX A SMP Negeri 4 Boyolali Semester Genap Tahun Pelajaran 2012/2013
Abstract
The purpose of this study was to describe the optimization problem solving skills
predictions about national exam mathematics courses through Jigsaw approach at a ninth
grade students of State Junior High School 4 Boyolali. Subject and source of research data
were do students of class IX A. The methods of collecting data were questionnaires, documentation,
and test. Data were
analyzed using a critical and comparative analysis. Indicators
of
success or graduation used criteria 5.5 (scale 4) or 55 (scale 100) and a target
of 100%
completion.
The procedure
used a classroom
action research
study conducted in three
cycles,
the
first
cycle
was
as
initial
condition,
while
the
second
and
third
cycles
were
as
action.
The
results
of research
suggest that: (1) the motivation of participants students in learning mathematics
courses before
cycle can be described increase
in the result,
namely from
before
cycle
to
the
first
cycle,
an
increase
of
before
cycle
is
average
of
56
to
the
first
cycle
of
an
average
of
58
(4%),
of
the
first
cycle
an
average
of
58
the
second
cycle
to
an
average
of
79
of
21
(36%).
Thus,
the higher motivation of learners shows an impact on learning outcomes. While the
mathematics
learning outcomes can be described increase
in the result,
namely from
before
cycle
to
the
first
cycle,
an
increase
of
before
cycle
average
of
45
to
the
first
cycle
an
average
of
59
of
14
(31%),
from
the
first
cycle
an
average
of
59
to
the
second
cycle
mean
average
69
of
10 (17%). Finally it can be said that using jigsaw for optimization problem solving skills
predictions about national exam mathematics courses is recommended.
