ABSTRACT Name : IsmaHendra Student No :1309200080070 Depertment/Program : English Education/Postgraduate Title : The Use of Information Gap Technique in Teaching SpeakingSkill(An Experimental Study at the Second Year’s Students of SMAN 5 Takengon) Key Words : Information Gap Technique, Teaching Speaking. Students usually get problems in developing speaking skills due to such as lack opportunity to speak, their inhibition or anxiety or lack of motivation. The objectives of the study are: (1) to examine whether there is a significant difference in speaking achievement between the students who are taught by using Information Gap Technique and those who are taught through traditional method, and (2) to explore the students’ response toward the use of Information Gap Technique. This experimental study was conducted to the second year students at SMAN 5 Takengon in the 2016/2017 academic year. There were two classes taken as sample: one as an experimental group and the other was as control group. The sample was taken by using random sampling. The data were analyzed by using t-test through SPSS for speaking test and percentage for questionnaire. The result of finding shows that Information Gap Technique is more effective than traditional method (teacher-centered) to teach speaking; this is proven by the result of t-test, in which the finding shows that t-test of pre-test of experimental and control group was 1.3 (t count t table) which means that there is no significant difference between two scores of both classes. However, t-score for the experimental class and control class is5.1 (t count t table) which indicates that there isa significant difference between experimental and control group post-test. The students have a quite positive response (95.1) to the use of Information Gap Technique to their speaking classroom. It can be concluded that the Information-Gap provides a positive contribution for the development of the students’ speaking performance.
