Pengaruh Strategi Pembelajaran Berbasis Proyek dan Kooperatif Tipe Group Investigation (GI) terhadap Kemampuan Berpikir Tingkat Tinggi SMA
Abstract: This research is
aimed to study the effect of project based , cooperative type GI and
conventional learning strategies on higher order thinking ability of graders XI
SMAN 2 Pematangsiantar. This quasi experiment was implemented as pre test and
post test control group design. The population was all grades XI MIA SMAN 2 Pematangsiantar
in Academic Year 2014/2015, consisted of seven classes. As many as three
clasess XI 4 (PjBL), XI 5 (GI) dan XI 7 (conventional) were chosen as samples
by cluster random sampling technique. Research instruments was higher order
thinking ability (Cognitive test C 4 -C 6 ). The parametric assumptions showed
that the data were normally distributed and homogenous. The Anacova and Tukey’s
test, were used for hypothesis testing by using SPSS v.19 statistical software.
The result showed that project based learning, cooperative type GI and
convensional learning strategies significantly affect student higher order
thinking ability (F=14.24;P=0.000). Students who were taught by project based
learning strategies (77,88 ± 7,35) had significantly different higher order
thinking ability compared with those who were taught with cooperative type GI
(71,10 ± 6,95) (P=0.001) and conventional learning strategies (68,05 ± 10,38)
(P=0.000) even thought cooperative type GI learning strategies wasn’t
significantly different compared with conventional learning strategies
(P=0.237). Based on the result of research can be concluded that students
higher order thinking ability on project based learning had higher than
cooperative type GI and conventional learning strategies.
