Abstract


The purposes of this research were to know the effectiveness of mathematics learning with scientific
approach through the cooperative model of type numbered heads together (NHT) in terms of student achievement,
the effectiveness of mathematics learning with scientific approach in terms of student achievement, and to know
which one was more effective between mathematics learning with scientific approach through the cooperative
model of type NHT and with scientific approach without NHT in terms of student achievement. This research used
quasi-experimental with pre-test and post-test control group design. Its population was all students of grade X SMA
Negeri 1 Kalasan. The samples were class X MIA 2 as experiment class which given scientific approach through
the cooperative model of type NHT and class X MIA 1 as control class which given scientific approach. The
instruments used in this research were learning instrument, i.e. lesson plan and student worksheet, pre-test and posttest as test instrument to measure student achievement, and observation sheets as non-test instrument. The
hypotheses testing used were one sample t-test and independent sample t-test. The results indicated that
mathematics learning with scientific approach through the cooperative model of type NHT was effective in terms
of student achievement. Mathematics learning with scientific approach was also effective in terms of student
achievement. But, the post-test result means between the two classes were not significantly different. So, the
mathematics learning with scientific approach through the cooperative model of type NHT was not more effective
than mathematics learning with scientific approach without NHT in terms of student achievement.
