Abstract

WWE-pigai is a kind of upgraded automated writing evaluation (AWE) system and there are 444,877,400 essays submitted and corrected on this platform. Some previous research on AWE system indicates that students do not tend to utilize AWE feedback to revise essays and improve writing abilities. The major objective of this study is to investigate Chinese EFL college students’ writing through the comparison of WWE-pigai and traditional writing method. The study lasts two terms and 120 Chinese colleges students participate in the research. The findings reveal that WWE-pigai can motivate EFL students to revise and resubmit their essays more than ten times, improve the scores, increase students’ grammar accuracy and vocabulary richness. The surface-level spelling errors (including punctuation mark misuse) are the most common for freshmen. WWE-pigai is not very effective to correct certain grammatical errors besides spelling and conjugation errors. For certain grammatical errors that the students cannot correct by themselves, the assistance of EFL teachers is necessary. We argue that the results reached through this study can offer useful implications for the usage of EFL writing strategies.
