This study observed the amount of writing produced by middle-school students in Korea during time-directed writing tasks. Time-directed writing tasks on familiar topics (e.g., movies, sports) were assigned to first- and second-year middle school students, with time limits of 10, 20, and 30 minutes. There were four significant findings. First, the average of number of Korean characters produced was 261.2 in 10 minutes; 325.5 in 20 minutes; and 571.7 in 30 minutes. The number of t-units was 7.6 in 10 minutes; 10.2 in 20 minutes; and 15.6 in 30 minutes. Second, the amount of writing increased according to the time allowed to the writing task. Third, there was no significant difference in the amount written by first- and second-year students, except when the writing task was limited to 10 minutes. Fourth, the amount of writing was higher among the female students than the male students.
