Havinginsufficient mastery in vocabulary causes difficulties for students to communicatetheir ideas both orally and in written forms. Moreover, the students also haveproblems in understanding the written and spoken ideas in terms of reading andlistening. Because of the importance of vocabulary, it requires teaching andlearning process with a suitable media that invites students‟ participation. WattpadApplication is a media - based IT offers relax and pleasant atmosphere that cansupport students learning. The study was done to verify whether or not the use ofWattpad was effective to teach students‟ vocabulary mastery.The formulation of the research problem was “Is there any significantdifference vocabulary mastery of the students‟ taught by using WattpadApplication and those taught by using a conventional method?”.Research method: 1) the research design of this study was Quasiexperimental with quantitative approach, 2) the population of this study was firstgrade students of SMAN 1 Karangan Trenggalek, 3) the samples were X IPA 2class consisted of 36 students and X IPA 4 class consisted of 36 students whichwere selected by using purposive sampling, 4) the research instrument was test, 5)the data analysis was using independent T-test.The finding showed that Wattpad Application was effective to improvevocabulary mastery of the students in experiment group. The effectiveness of theWattpad Application can be shown in the following descriptions: 1) the meanscore of experimental group in pre-test was 50.56, and after being taught usingWattpad Application the mean score of post-test was 77.36. The difference gainedof the mean score was 26.8. 2). Meanwhile the mean score of control group inpre-test 43.75, and after being taught using conventional the mean score of posttest was 59.17. The difference gained of the mean score was 15.42. From thedifference the gained mean score between pretest and post-test of the two groups,it revealed that the experimental group got better improvement of the mean score.3) the result of computing the mean score of post-test of the two groups usingindependence t-test at significance level of 0.05 showed that the significancevalues (sig-2 tailed) was 0.00 smaller than 0.05 (0.00 < 0.05). The result indicatedthat there was significant different mean score in vocabulary of the experimentalgroup taught using Wattpad Application and those taught by using conventionalmethod. Consequently, Null hypothesis saying that there is significant differencemean score in vocabulary of the students taught by using Wattpad Application andthose taught by using a conventional method at the first grade of SMAN 1Karangan was rejected and Alternative hypothesis saying that there is nosignificant difference mean score in vocabulary of the students taught byusing Wattpad Application and those taught by using a conventional method at thefirst grade of SMAN 1 Karangan was accepted. Thus, ONLINE WattpadApplication was effective media to teach students‟ vocabulary.
