Abstract :
This study was conducted based on the consideration that 5E model has
never been applied at SMK Bahrul Ulum, and the school was new established in
2008 ,and there is no specific subject for vocabulary in senior high school. The
students have difficulty to speak English well, after the researcher interviewed the
teacher.
This study is aimed to finding the significant effect of 5E (engage, explore,
explain, elaborate, evaluate) model to improve vocabulary at tenth grade of senior
high school SMK Bahrul Ulum Menganti Gresik. To achieve this purpose, the
researcher applied quasi-experimental pre-test and post-test design.
The design of this study is quasi experiment with non randomized pre-test
and post-test. In order to know the effect of 5E model,the researcher was carried
out at SMK Bahrul Ulum Mnganti Gresik from April 20th 2012 to May 7th 2012.
The sample was taken from best classes which have the best English score at final
test in first semester of SMK Bahrul Ulum Menganti Gresik tenth grade at SMK
