Abstract:
The objective of this research was to find out the effect of Using Clustering
Technique on the Students’ Achievement in Writing Assisted by T-Card With
Keywords. This research applied experimental research design namely one group
pre-test and post-test. The population of this research was taken from the Eight

technique. The instrument of collecting data is writing test. The data were
analyzed by using t-test formula. The mean of pre-test increases after clustering
technique from 62.05 to 80.45. The value of the effect was 64%. The result of the
data showed that was higher than (7.7>2.03452) with degree of
freedom (df) = n-k. The hypothesis was accepted. It proves that Clustering
Technique significantly effect to the students’ achievement in writing.
