Abstract: This research was aimed to know: the student’s ability at writing news that were taught by using advertisement text, the student’s ability at writing text that were taught by using lecturing method and to find out whether there was significant effect of advertisement text on the student’s ability at writing text. The research methodology of this research was an experimental research which conducted the experiment and control class. The population of the research was the tenth grade students of laboratory islamic school (MAL UIN) Medan in 2015/2016 academic year, the number of students was 46 students consist of two classes. The experiment class (X₂) was 22 students and control class (X₂) 24 students as sample. The researcher gave writing test to collect the data. There were two test; pre-test and post-test. The formula that was used to analyze the data was independent sample t-test. The researcher found that the pre-test mean of experiment class was 60.40 and control class 58.78. Post-test mean of the experiment class was 79.31 and control class was 62.07. It was found that t_observation was 9.70 whereas the t-table was 2.002 for α = 0.05. The t_observation was higher than the t_table (9.70>2.002), so Ha was accepted while H was rejected. It means that there was significant effect of 0 advertisement text on the student’s ability at writing text The data was analyzed by product moment correlation. After analyzing the data, the writer finds that there is a significant correlation between mastering simple present tense and the student’s ability to build up advertisement text. It is known ∑x = (3477), ∑y = (2930),∑x = (280497),∑y = (202000),∑xy = (226460), the coefficient correlation is (0.3026). While rt (0.294) at % It means ro>rt (0.3026>0.294). So, the hypothesis is accepted.
