The main objective of this study is to find out whether there is or not a significant difference of student’s vocabulary achievement between students who taught by using Picture Word Inductive Model and those who are taught by using explanation only. The hypothesis of this study is there is a significant difference between the student’s vocabulary achievement between students who taught by using Picture Word Inductive Model and those who are taught by using explanation only.
The researcher used Picture Word Inductive Model in teaching vocabulary at the seventh grade of MTs Sunan Kalijaga Bawang Batang in the academic year of 2010/2011. In this research, the population is the seventh grade of MTs Sunan Kalijaga Bawang Batang in academic year of 2010/ 20011.The number of the population was 182 students. In taking the sample, the writer used cluster random sampling technique.

The average of post- test of experiment class is 77.6 which were higher than the average of post test of the control class 72.6. The t-test result (2.5) was higher than the t- table (1.98). Since the t-test was higher than t- table, the hypothesis is accepted. It means that there is a significant difference in student’s vocabulary achievement between students who taught by using Picture Word Inductive Model and those who are taught by using explanation only.
