Afterwards, they were randomly assigned to two groups of 30, experimental and control group. Participants in experimental group received the AES scoring, and control group, received the human scoring. Statistical analyses of the results reveal that 1) AES tool results in significant improvement of L2 learners writing achievement, 2) Results from questionnaire show that Students ware favor about using AES tool, 3) The results from the current study support the conclusion that the AES tool does not seem to correlate well with human raters in scoring essays.
