Instruments of quantitative research were based on the new instructional model of Cooperative Learning. Ten sample lesson plans were constructed. The target population is Grade Eight students in Yangon Region. Stratified random sampling method was used. Four sample schools were selected by using random sampling method. In each school, students were randomly selected and assigned to two groups. Quasi-experimental designs were applied in the experimental research and it took about ten weeks. Descriptive statistics was used to calculate students’ mean score, standard deviation in narrative and descriptive writing skill of students. Also the percentage of students’ attitude questionnaires were descriptive in data analysis. Furthermore, independent samples t- test and ANCOVA were used to test the significant level. Moreover, Pearson correlation was applied to analyze the correlation of the variables. And, questionnaires for students and teachers were conducted to find out teachers’ and students’ attitudes towards Cooperative Learning Model. The qualitative research was conducted with students’ and teachers’ interview questions for teachers and students. The result of this study shows that there was a significant difference in the writing skill of students between those who are taught by Cooperative Learning Model and those who are not.
