The mean score of posttest was higher than the mean score of pretest (75.76>60.52). The result of statistical analysis the experimental group for level of significance 0.05 with degree of freedom (df) = 24; the probability value was smaller than α 0.00<0.5 and the result of statistical analysis the control class in which the probability value was lower than α .0.00>0.05. As a result, there was a significant difference in writing achievement between the students who are taught by using estafet strategy and those who are taught by non-using estafet strategy.
