Abstract :
The research was intended to know the effectiveness of Word Find Puzzle in the
students? vocabulary mastery which was observed and analyzed from students of
tenth grade at SMA Baitul Aziz Bandar Klippa. The method utilized was
quatitative research by using the experimental research design. The population of
this study was tenth grade students of SMA Baitul Aziz Bandar Klippa. In taking
the sample of this research, the researcher took some students in each classes as the
sample utilized and divided into 2 classes, experimental and control. There were 34
students in the experimental and 26 students in control. The researcher treated by
using the Word Find Puzzle in the experimental class and treated by using lecturing

control class the score increase 59,23 between pre-test and post-test, but in
experimental class the score increase about 68,85. By calculated by utilized SPSS
V24, The researchers concluded that there was a significant effect of the application
of the Word Find Puzzle learning approach on learning outcomes, it can be seen
from the results of the analysis that this is indicated by the results of hypothesis
testing which indicate that the Sig. (2 - tailed) <0.05 (0.000 <0.05) and the value of
t_ (count)> t table (6.365> 1.992). Then in post test the researcher found that the
value of Sig. (2tailed) is 0,923. It is bigger than 0,05 (0,923>0,05) Sig. in T-Test
(2tailed) is 0,002. It was less than 0,05 (0,002>0,05), so the researcher found a
significant different between the experiment class and control class. In other words,
