The participants were 90 female elementaryninth-grade high school learners with age around 15, who were divided into the three experimental groups afterensuring their homogeneity by Solution Placement Test. The design of the study was a quasi-experimentalmethod. The scores of the pretest at the outset of the study proved that all the participants equally lacked the ability in written production of simple present tense. All the experimental groups experienced six sessions ofgrammar treatment. The topic of the pre and post test for written production was the same. To investigate thefirst research question of the study, one way ANOVA was conducted.
