Abstract:
A research on the application of the learning model type Three Stay One Stray
has been conducted by purpose of increasing students achievement in learning
atomic structure and system periodic of element at grade X class of SMAN 1
Tambang. The pretest-posttest experiment group design was used in this research.
Research have done in 18 July until 9 September 2011 at grade X of SMAN 1
Tambang. Instrument of aggregation data was use homogeneity test and test
pretest-posttest. Data was analyzed with t-test at α=0,05. Result showed that the t
value was 2,12 while t-table was 1,67. Therefore, it could be concluded that the
application of the learning model type Three Stay One Stray with was able to
increase students learning achievement in atomic structure and system periodic of
element discussion at X class of SMAN 1 Tambang. The learning model
typeThree Stay One Stray can improve students because they are all active in
learning like group discussion and presentation in class.
