PERBEDAAN KEMAMPUAN MEMECAHKAN MASALAH DAN RETENSI MENGGUNAKAN MODEL PBL (PROBLEM BASED LEARNING) DAN CERAMAH BERVARIASI PADA MATERI KEANEKARAGAMAN HAYATI INDONESIA SISWA KELAS X MIA SMA NEGERI 2 SURAKARTA TAHUN PELAJARAN 2014/2015
ABSTRACT: This research aims
to find out: (1) The difference of
problem solving skill between PBL
model and lectures varies
in the Indonesian biodiversity material of X MIA grade of SMAN
2 Surakarta in academy
year 2014/2015; (2) The
difference of retention between PBL model
and lectures varies in the Indonesian
biodiversity material of X MIA grade of SMAN 2 Surakarta
in academy year 2014/2015. This research was quasi
experiment research with using postest only nonequivalent control group design.
The population of the research was all student of grade X MIA of SMAN
2 Surakarta as much as five grades. The sampling technique of the
research used cluster sampling, therefore
the X MIA 5 grade becomes the
first experimental class and the X MIA 4 grade becomes the second
experimental class. The sampling technique is taken from the test and
non-test. The test is used in order to measure the problem solving skill and retention. Problem
solving test used to measure the problem solving skill. Posttest and retest
used to measure the retention.
Retest have done in two weeks
after the posttest. Non-test is an
observation sheets used to measure syntaxes occurrence, documentation is used
to collect the data in order to gain the equality test. The result of the
hypothesis test by the t test for the
difference of problem solving skill between PBL model and lectures
varies show the signification value in 0,00 (sig.<0,05) and the value of
tcount is 5,654. Problem solving skill with PBL model is better than lectures
varies. The signification value of the
difference of retention
between PBL model and the lectures varies as big as 0,00 (sig.<0,05) and the value of tcount is
5,627. Retention with PBL model
is better than lectures varies. The result of the research summarizes
that there is differences of problem
solving skill between PBL model and the
lectures varies in the Indonesian
biodiversity material of X MIA grade of SMAN 2 Surakarta in academy year
2014/2015 and there is differences of retention between PBL model and lectures varies in the Indonesian
biodiversity material of X MIA grade of SMAN 2 Surakarta in academy year 2014/2015.
