The main purpose of the study is to measure the effect of using pictures toward the vocabulary achievement at the seventh grade students of MtsDarul Amin Palangka Raya. The type of study was quasi-experimental especially non-randomized control group, pre-test post-test design and the writer used quantitative approach in finding out to answer the problem, the data collecting technique used test and documentation.
There were two classes of study namely VII-B as experimental group and VII-A as control group with the total number students which VII-B the total students are 22 and VII-A class the total students are 22. The sample of study is determined using cluster sampling technique. Both groups were given pre-test before treatment. Then, the students of experiment group was taught by using pictures and control group was taught without using pictures. Finally, the writer gave post-test to both groups. The normality of the test was pre test and post test of the experiment group in Kolmogorov-Smirnov was higher than level of significance alpha used or r = 0.714> 0.05 (Pre Test) and r = 0.148> 0.05 (Post Test) so that the distributions are normal. The homogeneity (probably value/critical value) from pre test and post test of the experiment group on homogeneity of variances in sig column is known that p-value is 0,566. The data in this study fulfilled homogeneity since the r value is higher 0,556> 0.05.
In the result of hypothesis was using calculation of T-test with SPSS 18.0. The result of t-test with SPSS 18.0 calculation found the calculated value (tobseved) was greater than ttable) at 1% and 5% significance level or 2.02 2.71. it was interpreted than alternative hypothesis (ha) stated that students taught vocabulary using pictures media gain better score than the student taught vocabulary without using pictures media was accepted and the null hypothesis (h0) students taught vocabulary using pictures media does not gain better score than the students taught vocabulary without using pictures media was rejected. It meant that using pictures in teaching gives effect on the students’ vocabularies at the seventh grade of MTs Darul Amin Palangka Raya.
