The data in this study was the scores of writing the observation report. Those data are gathered by using performance text as the instrument. Then, after collecting the data, they were analyzed. The results of data analysis are that : (1)The level of skill in writing the observation report text before using the STAD type modul berbasis STAD-based cooperative learning modul obtained an average score of 65,24. it means that the scores are in the level 55-65% mastery with “Enough (C)” qualification. (2) the level of skill in writing the observation report text after using the STAD type modul based STAD-based cooperative model gained an average score of 72,62, which was at the 65-75% mastery level in More than Enough (Ldc) qualifications. (3) It can be concluded that the STAD type modul berbasis STAD-based cooperative model influences the writing skills of observation reports text with t count> t table, namely (3.41> 1.67).
