Abstract

Vocabulary learning is an important life-long experience. English learner will be difficult to create a text and learn the language without knowing its meaning. In this study the researcher tries to use interactive multimedia to teach vocabulary. The objectives of this study are (1) to find out the students’ vocabulary mastery taught with interactive multimedia, (2) To find out the students’ vocabulary mastery taught without interactive multimedia, (3) to find out whether there is significant difference or not in vocabulary mastery between students taught with interactive multimedia and those taught without interactive multimedia. The population of this study is the eighth grade students of MTs Nurul Huda Raji. The total population is 117 students. The writer took two classes as the subjects of the study. The classes are, VIII A, VIII B. They are divided into experimental class (VIII A) and control class (VIII B). Each class consists of 40 students. A test as the instrument was used to collect the data. The research was started by conducting the try out test measuring the validity, reliability, discrimination power and level of difficulty of the test. The data were computed and it was found out that 30 items were valid. Then the valid items were used for the pre-test and posttest of vocabulary item tests in experimental and control class. The average score of the pre-test of the experimental class was 17.10 and control class was 18.53. The students in the experimental class were then taught using interactive multimedia while the students in control class were taught without using interactive multimedia. After that they got the post test. the results of experimental group score increase by 4.90 (17.10 to 22.00), while the control group score improves by 1.62 (18.5 to 20.15). It means, there is a 10,93% improvement difference in the two groups. The posttest scores of experiment and control group then were calculated using t-test to know whether there was significant difference between the experimental class and control class. The t-test was 3.527 and t-table was 2.042. The data shows that t-test was higher than t-table. It means that there was significant difference between the experimental class and the control class.
