摘要:Journal writing is believed to be a significant tool to promote reflection. Some studies have been carried out to test that, most of which have been solely concerned with the participants’ perceptions, leaving the actual application of reflective practice in EFL teaching practice untouched. Hence, to fill this gap in the literature, the researchers initiated this study. The participants were 24 EFL teacher trainees at a teacher training center in Guilan province. A questionnaire, including closed- and open-ended items, and an observation checklist were utilized. The researchers conducted matched t tests to investigate the possible differences between the perceptions and application of reflective practice before and after treatment. The questionnaire and checklist data were analyzed quantitatively and descriptive analyses were run. A qualitative content analysis was also employed for the open-ended item of the questionnaire. The results indicated that journal writing had a significant effect on promoting reflective practice in teacher trainees. There was also a significant difference between participants’ perceptions and application of reflective practice before and after treatment.
