#### Abstract

The aim of this research is to prove the difference of ability in arranging

explanation text between the students following the learning using a Role-Audience-

Format-Topic (RAFT) and the students following the learning without RAFT

strategy. Beside, this research is also aimed to test the effectiveness of RAFT strategy

in the learning of arranging explanation text to the students of SMP Negeri 15

Yogyakarta class VII.

The research design used is a quasi experiment with control group pretest-

posttest design. There are two variables in this research, they are independent

research in the form of RAFT strategy and dependent variable in the form of the

ability of arranging explanation text. The population of this research is the students of

SMP Negeri 15 Yogyakarta class VII. The sample is taken by using cluster random

sampling, there is class VII C as the group experiment and VII D as control group.

The data collecting technique is using a test of arranging explanation text. The

difference in the ability in arranging an explanation text between the students

following the learning using RAFT strategy and the students following the learning

without RAFT strategy in SMP Negeri 15 Yogyakarta class VII. The difference can

be known from the result of test-t final score experiment group and control group is

got p as 0,001 so that p < significance level 0,05 means significance. Second, it is

proved that RAFT strategy is effective used in the study of arranging explanation text

to the students of SMP Negeri 15 Yogyakarta class VII. The effectiveness of this

RAFT strategy can be known from the result score of test-t pre-test and post-test
