The purpose of this study is to verify the efficiency of VanPatten’s (1996) Processing Instruction model in the teaching of English relative clauses in two different groups of participants: an intervention group and a traditional group. These two groups of students were enrolled in a BA in ELT. This study was conducted online due to the pandemic of Covid-19, where a pre-test and a post-test were administered to the intervention group, and only the post-test was administered to the traditional group. The statistical analysis shows a significant difference between the intervention group scores on the pre-test and post-test as well as a significant difference between the traditional group and intervention group. For the qualitative part of the study, the intervention group completed a feedback questionnaire, and the results show that most students consider that employing this model for language teaching is an effective approach in the teaching of relative clauses.
