EKSPERIMENTASI MODEL PEMBELAJARAN GROUP INVESTIGATION (GI) DAN THINK TALK WRITE (TTW) DENGAN PENDEKATAN PENDIDIKAN MATEMATIKA REALISTIK PADA MATERI RELASI DAN FUNGSI DITINJAU DARI KREATIVITAS BELAJAR SISWA KELAS VIII SEMESTER 1 SMP N DI KABUPATEN SRAGEN
Abstract: The objectives of
this research were to find out: (1) which students had the better mathematics
learning achievement, those treated with direct learning, those with GI with
PMR or those with TTW with PMR approach, (2) which students had the better
mathematics learning achievement, those with high or medium or low learning
creativity, (3) in each learning creativity, which students had the better
mathematics learning achievement, those treated with direct learning, those
with GI with PMR or those with TTW with PMR approach, and (4) in each learning
model, which students had the better mathematics learning achievement, those
with high or medium or low learning creativity. This research was a quasi
experimental research employing 2 independent variables (learning model and
learning creativity) and 1 dependent variable (mathematics learning
achievement). The population of research was all of the VIII graders of Public
Junior High Schools in the school year of 2013/2014. The sampling technique
used was Stratified Cluster Random Sampling. The sample students consisted of
three schools: SMP Negeri 1, SMP Negeri 6 and SMP Negeri 2 Karangmalang Sragen.
The proposed hypotheses of the research were tested by using the two-way
analysis of variance (ANAVA) with unbalanced cells with the factorial design of
3 x 3. The results of research were as follows: (1) the students treated with
direct learning model had learning achievement as good as those with GI
learning model with PMR approach, those with TTW learning model with PMR
approach had learning achievement better than those with direct learning, while
those with TTW with PMR had learning achievement as good as those with GI
learning model with PMR approach, (2) the students with high learning
creativity had learning achievement as good as those with medium one, those
with high and medium learning creativity had learning achievement better than
those with low one, (3) in each learning creativity level, the students treated
with direct learning model had learning achievement as same as those with GI learning
model with PMR approach, those with TTW learning model with PMR approach had
learning achievement better than those with direct learning, and those with TTW
with PMR had learning achievement as same as those with GI learning model with
PMR approach, (4) in each learning model, the students with high learning
creativity had learning achievement as same as those with medium one, those
with high and medium learning creativity had learning achievement better than
those with low one.
