Finally, 10 respondents were interviewed to generate their perceptions on the utilisation of this technique as implicit WCF in their writing tasks.Results. The results showed that the students had achieved a slightly significant improvement in their essay writing skills after the treatment, and they perceived positively the utilisation of the lecturer's indication of errors as implicit WCF in their essay writing tasks.
