One group was excluded from the four groups by administering unified principles. After the pre-test, the participants were divided into four groups. Three groups instructed through a paragraph writing development syllabus (16 sessions). However, the experimental group was tested through unified materials development. The collected data were analyzed using ANOVA procedures. The study also tried to show ways of clarifying the stages in writers’ thinking under characteristics of paragraph writing development. To analyze the test hypothesis, covariance analysis was used. The results of both tests of the group instructed through unified materials development indicated that there was significant positive correlation among post-test scores of learners.
